Back in 2020 I bought a set of gymnastic rings, and used them for pull ups, dips, and inverted rows during the period that fitness rooms were closed due to the pandemic. More recently, I’ve been doing a lot of club and kettlebell swinging—using equipment that was unavailable during the pandemic, but that I’ve purchased since.

I like the club and kettlebell stuff. However, probably because I’m not programming the workouts as well as I might, I don’t seem to be making progress. In fact, in some ways I’m backsliding. So, now that the weather supports getting outdoors and putting my rings up again, I’m going to do more of those workouts.

Today I did a circuit with three rounds of:

  • Jump rope (x110, x120, x120 jumps)
  • Dips (sets of 1 full dip + 5 negative dips)
  • Wall sit (1 set of 30″ left/right legs, 2 sets of 45″ two-leg)
  • Inverted rows (x7, x9, x9)
  • 3-way core (30″ each of hollowbody hold, inverted plank, shoulder taps)

This picture has nothing to do with my workout. I took it while walking the dog at dawn.

Based on the ideas that I talked about in Training for everything, here’s my latest cut at a personal exercise program. (My first cut was derailed by circumstances, and then I adopted a dog which derailed everything except dog walking. Then I got West Nile fever.) See my no-longer-particularly-recent Starting to rough up a new training plan for more information about the specific exercises and how I organize them into sets, reps, and progressions.

I have a set of exercises that I want to do, ideally twice a week each:

  • Kettlebell swings
  • Kettlebell clean & press
  • 1-handed heavy club swinging
  • Bodyweight gymnastic rings circuit
  • Run

That’s five things, so if I did each twice, and gave everything its own day, I’d have to have a 10-day week. That isn’t impossible. In fact, I’ve seriously considered planning my workouts in a longer cycle than weekly in the past, it but is unhandy in various ways. Fortunately, I think I can double-up several of these exercises in a way that will let me fit them into 7-day week.

The 1-handed club swinging isn’t particularly intense cardiovascularly, so I’m thinking I can combine it with the clean & press. The KB swings is intense cardiovascularly, but because it’s very different, I’m thinking I can combine it with the gymnastic rings bodyweight circuit, doing the KB swings as a “finisher” after the rings workout.

My HEMA (sword fighting) practice is three times a week, and I can’t adjust that schedule, except by skipping workouts, so I have to work that in when it actually happens.

A heavy club,  a fencing mask, two pairs of fencing gloves, two translations of Meyer's text of sword fighting, a kettlebell, and a sword

Of course I also want to get one day a week of complete rest. I’d normally make that Sunday, but there’s a HEMA practice session on Sunday so it’ll have to be on Saturday instead.

So here’s a quick stab at a possible weekly plan:

DayMorningMiddayEvening
SundayRings circuit / KB SwingsHEMA
Monday1-H Heavy Club / KB C&P
TuesdaySprintsHEMA
WednesdayRings circuit / KB Swings
Thursday1-H Heavy Club / KB C&PHEMA
FridayLong run
SaturdayRest

I’ve omitted a “warm-up” block, because I already do my morning exercises, my ridiculously long warm-up routine, nearly every day. I’ve also omitted my dog walking, which averages something over 6 miles a day.

I’m pretty happy with this. It has my HEMA practice sessions in at the correct times; it leaves open the time slots where I have Esperanto, and meeting friends for lunch; it has a full rest day.

I don’t show it here, but I’ll definitely do a de-load week every 5 or 6 weeks.

I should be very clear that, at this point, this is entirely aspirational. I’ve been doing each of these workouts individually, but the only combined workouts I’ve tried so far are the heavy club swinging and the clean&press workouts. I’ve also been taking more than one rest day per week. But the progress I want seems to depend on doing something like this workout schedule, so I’m going to give it a try.

I’ll report back regarding my success or failure.

During the pandemic I followed something of a training plan—a mostly bodyweight exercise plan with minimal equipment beyond a pair of gymnastic rings, based largely on Anthony Arvanitakis’s Bodyweight Muscle books and YouTube channel.

Post-pandemic (once my local fitness room reopened, and exercise equipment became available again), more activities became possible. As they did, I added some in. With extra stuff to fit in, I let the program go. Instead I began exercising more intuitively—simply trying to fit in my strength training and my running as best I could. Each day I’d decide what to do influenced by how I felt, and what I’d done (or hadn’t done) the previous day or two, trying to cover all the bases, while allowing adequate time for recovery.

It has worked pretty well, but not as well as I was doing with an actual program. However, I don’t want to go back to the bodyweight rings program, because I feel like I’m getting real benefits out of the kettlebell and heavy club activities. So, I’m working on roughing up a training program that includes all the stuff I want to do.

Goals

It probably doesn’t make any sense to talk about the activities I do without thinking about the goals I’m trying to achieve.

Of course, I want to feel fit and healthy.

In the spirit of Peter Attia’s Centenarian Decathlon, I want to not only be capable of all the activities of daily living, but have enough reserve capacity now that I’ll still be able to do those things when I’m eighty, ninety, or (as I like to joke, except I’m totally serious) eleventy-one.

Among those things are the obvious—be able to hike a few miles on a rugged trail, climb a steep hill or several flights of stairs, carry a heavy bag of groceries home, put a suitcase in the overhead compartment, get down on the floor and back up again, etc. Besides those, I also want to be able to do well at longsword, which requires the ability to stand and walk in a low lunge, hold the sword with my arms at full extension (both forward and over my head), etc.

Fitness Activities

I figure the first step is just to document the activities that I think will support these goals, so that I know what I want to fit into the week. Here’s my first pass at a list. (Note that I already do an extensive warm-up every day, because it makes me move and feel better all day, whether I do a workout or not. I also walk my dog, and she rather insists on at least 6 miles a day.)

HEMA practice

My group has 2-hour meetings three times a week. They’re mostly skills training, so not too intense, although now that I’m approved for sparring the intensity has gone up.

Running

I want to go for two runs per week. One is a “long” run, in the 6–10 mile range (although I may want to work up to half-marathon length). The other is a “fast” run, which might include sprints, hill sprints, or just a hard run in the 3–4 mile range.

Kettlebell swings

This is primarily to work the muscles of my posterior chain, which needs a regular workout to keep me functioning well. In particular, I learned the hard way what happens if I don’t work my glutes. Currently I’m doing a heavy/light cycle, where I alternate between swinging an 18 kg (40 lb) kettlebell and a 24 kg (53 lb) kettlebell.

For the light kettlebell I’ve worked up to 10×19 swings emom. For the heavy kettlebell I’ve worked up to 10×12 swings emom. I try to add one swing per set every week.

Somewhere around sets of 25, I’d no longer get any break at the end of a minute. I don’t yet know if that’ll mean I’ll be able to do 250 straight swings.

Heavy club swinging

This is one of my newer additions, and I have already seen it do great things for rotational strength, plus grip, arm, shoulder, and core strength. As the weight has gone up, it has started hitting the legs as well.

I do three exercises (outside circle, shield cast, inside circle) in sets of 5 left and 5 right, and I work up from 5 sets on each side, adding one set every workout or two, until I get to 10 or 12 sets on each side, and then go up in weight. I’m up 8 sets with a 13.75 pound club. Soon I’ll go up to 15 lbs.

Kettlebell clean and press

This one seems especially useful for longsword, where you often need to hold the sword over your head, with your arms near full extension.

I do these as a reverse ladder, starting with 4 reps on the left and 4 reps on the right, then 3, then 2, then 1 rep on each side. Then I take a short break and repeat for some number of sets. Each workout (or every other workout) I add one set.

I just did 7 sets. I’ll work up to 10 or 12, then either increase the weight or else start the reverse ladder at 5 reps left and right, and go back to workouts of 4 or 5 sets.

Gymnastic rings circuit

Versions of this were my main workout all through the pandemic, when fitness rooms were closed and kettlebells impossible to come by. These were push/pull/legs workouts preceded by a starter and then ended with a core exercise. I had at least a couple variations of each exercise, so the starter was often jumping rope, but sometimes some sort of quadruped movement, push generally alternated between dips and some version of a push up, pull alternated between pull ups and inverted rows, legs was often air squats, but sometimes hindu squats or lunges or wall sits, and core was often hollowbody hold, but sometimes planks or reverse planks or V-ups.

I’d set the number of reps of each exercise at what I thought I could carry through for 3 rounds, and the 3rd round I’d aim to push to technical failure.

Toward a schedule

Putting all these things into a weekly schedule has proven to be difficult.

Me standing in zornhut

One issue is that my HEMA practice sessions occur at specific times, so there’s a certain lack of flexibility in the schedule there.

Besides that, there’s simply more stuff I want to do than fits easily into a week.

One solution to that would be to abandon the idea that “weekly” is the right structure. I could fit things into, let’s say, a 9-day cycle—but there are enough inconveniences with that, that every time I’ve considered it before, I’ve ended up sticking with weekly.

I’m pretty close to having a first cut at a weekly schedule ready to post. Look for it here in a day or two. (Update: It took much more than a day or two, but you can now see my Personal exercise program for winter 2023-2024.)

Rings on a pull up bar, weights, yoga mat, etc.

I originally got gymnastic rings 18 months ago, when Winfield Village closed its fitness room due to the pandemic.

It’s a great fitness room, and I’d really enjoyed using it for workouts over the previous six years or so, but once I started doing my workouts outdoors with gymnastic rings, I found that I liked that even better, so I carried on with my outdoor workouts even after the fitness room reopened this spring.

These last couple of weeks, the weather is no longer as nice as it has been since early April, so I’ve started experimenting with ways to move my workouts back indoors, without losing the extra fun I’ve been having with gymnastic rings.

Last week I did an indoor workout that was very similar to what I’d been doing a couple of years ago. Today I tried to something more like my outdoor workouts—specifically, by bringing my rings along, and putting them up on the chin-up bar.

I did my usual morning exercises before heading over. Once I was in the fitness room, I put my rings up at the right height for dips or inverted rows, and did just a bit of additional warming up, doing some straight-elbow rows and straight-elbow push ups.

That done, I proceeded into my circuit, which consisted of the following for three rounds:

  • Skater hops x 35
  • Dips x 3 full dips + 4 negative dips
  • Goblet squats 35 lbs x 12
  • Inverted rows x 12
  • Hollowbody holds 60″ first two rounds, then 30″ for last round
  • Prone angels 2.2 lbs x 12

I still had a little energy after three rounds of that, so I did two rounds of a little mini-circuit to hit my deltoids, biceps, triceps, and forearms:

  • Zottman curls 15 lbs x 12
  • Dumbbell runners 15 lbs x 12 each side with one foot forward, then x 12 each side with the other foot forward

The whole workout took just over one hour, and left me feeling pleasantly tired, without making me feel so worn out as to imperil the run I have planned for tomorrow.

This year was obviously strange in all sorts of ways, so I figure it’s not so strange that my movement practice got strange.

One thing that seems very strange to me is that I reverted to doing a lot of exercise, after having made a big deal the past few years of scorning exercise in favor of movement. I wrote a whole post on this recently (Exercise, movement, training), so I won’t repeat all that stuff here, except to say that the pandemic response provided me with a lot of opportunities to exercise, while restricting my opportunities to move and to train.

Exercise

Around the beginning of the year I had a realization that what had held me back from achieving my fitness goals was not (as I had been supposing) a lack of intensity, but rather a lack of consistency. I responded by getting very serious of getting my workouts in, and was pretty pleased about having established a proper workout habit when just a few weeks later the pandemic led to our local fitness room being closed. I found this momentarily daunting.

As I’ve mentioned elsewhere, it was around this time I saw this hilarious tweet:

To which my response was “Challenge accepted!”

Resistance exercise

The biggest problem with losing access to the fitness room was losing access to the pull-up bar. I looked around for alternatives, found that gymnastic rings were available and affordable, and I ordered a pair.

Easily the best purchase I made last year.

The addition of gymnastic rings made for a big change in my exercise regimen. I use them for three exercises: pull ups, inverted rows, and dips. I had worked pretty hard on pull ups before, but upon getting the rings I redoubled my efforts. As far as inverted rows and dips, I had played around with both, but now I got serious.

I round out my upper-body exercises with push ups.

For lower-body exercises I experimented with a variety of possibilities: squats of various types, kettlebell swings, burpees, lunges, etc.

One milestone was achieving my first pull-up. Another was the first time I did two pull-ups. Later I manged (a couple of times) to do three pull-ups!

I just wrote about how kettlebell swings taught me something about the value of doing lots of reps. Based on that, for my indoor workouts (where it’s not handy to set up my rings), I’ve started doing more exercises for high reps. Not enough data yet to know how that’s going to work, but it seems like a valuable experiment.

Running

For a long time—at least many months, maybe more than a year—I’d had a sore foot that got worse when I ran. I repeatedly cut back or eliminated runs, had my foot get better, and then had it start hurting again as soon as I started running again. This past summer I finally took a full month off from running, which seems to have been what my foot needed.

I’ve very gradually resumed running. For some weeks I kept my runs down around just one a week and just 2–2.5 miles. Then up to a 3–3.5 miles. I did one 4 mile run, which didn’t seem to cause any problems, but then I did a run of nearly 5 miles, which did make my foot sore the next day. I took a break until the pain was completely gone and eased back to 3–3.5 miles, and all seems well.

I’ve just started doing two runs per week, a “long” run (slightly over 3 miles) and a “fast” run (where I hold the distance down under 3 miles, but include a few 10-second sprints around the mid-point of the run). That felt really good the last time I did it. (My running gait seems to improve when I run fast.)

Kettlebell swings

I’ve talked at some length about my adventures in getting a kettlebell during a pandemic, and about my experience with kettlebell swings producing unexpected hypertrophy, so I won’t repeat that here. I’ll just say that cold weather—and especially ice on the patio—have kept me from doing much kettlebell swinging in the second half of December. But literally every day I look out on the patio to see if it is clear of ice, and get out and do some swinging when it seems safe.

Jump rope

I added a jump rope to my exercise equipment a while ago, and back in March and April did enough rope skipping to recover the ability to do it. (That is, I could jump rope for 30 or 40 seconds with zero or one misses.) The problem was that jumping rope hurt my sore foot just like running did. I prefer running, so when I had to set limits on those exercises to protect my feet, I ended up mostly running, as long as the weather was nice.

As the weather turned chilly in the fall, and especially when we started having days when there was an occasional short period adequate weather, but not the sort of reliable block of nice weather that makes me think I can fit in a good long run, I started thinking that an occasional bout of jumping rope might be a great way to squeeze in a quick, intense workout during even quite a brief period of nice weather on an otherwise nasty day.

To make full use of such periods, I paid up for a weighted jump rope. I have to say I’m pretty happy with it. It’s very much the opposite of my old jump rope, which was just a plastic-coated wire—very light and very fast—marketed to martial artists and cross-fit types. Pretty good for getting lighter on your feet, and adequate for a lower-body workout, but not much for the upper body. The weighted jump rope (even the lightest one, at just ¼ lb) definitely turns the jump rope exercise into an upper-body exercise as well.

I haven’t had the weighted jump rope long enough to form a definite opinion about it, but after just a couple of sessions, I’m pretty pleased, and if the weather cooperates, I’m hoping to get multiple HIIT jump rope workouts in over the course of the winter.

Non-exercise movement

My main non-exercise movement is and always has been walking, but I’ve done very little this past year. This was half due to the pandemic, and half due to Jackie having a sore hip that makes it hard for her to walk fast or for long distances. (I’ve been taking Jackie to physical therapy, and she’s getting better. We’ve been doing walks in the woods south of the Arboretum, and that’s going very well.)

With fewer and shorter walks with Jackie, and with walking for transportation almost eliminated by the pandemic, my non-exercise walking has dwindled pretty severely.

Ditto for my non-exercise running.

Parkour

I have very much had my eye on parkour as the thing I want to get back to this summer. Since I have made great progress on strength training specifically with an eye toward parkour, I’m very hopeful.

I’ve been doing just a bit of training, even without being able to get together with other traceurs.

The most active member of the campus parkour group turns out to have moved to Colorado. I’ve been in touch with him, and he seems to mean to spend at least some time here this summer, so hopefully I can put together some sort of training with him. In the meantime, I ordered one of his t-shirts, so I’ll have something to wear.

Taiji

Like everything else, the taiji classes I used to teach at the Savoy Rec Center had to be abruptly canceled back in March.

During the spring I led a few group practice sessions via Zoom. They’re better than nothing, and at least keep the group connected.

Once the lock-down restrictions in Illinois eased up a bit in April, my group started meeting in the park, and we continued to meet through the summer. Once the weather turned, I resumed the on-line practice sessions.

Unlike a lot of my students, who don’t feel like they can do the taiji practice without someone to lead them, I can actually do a full practice session entirely on my own. And I occasionally do. But without the group being there, it’s hard to get motivated.

Still, I almost always include some qigong as part of my morning exercises, do the once-a-week group practice session, and occasionally do the full 48-movement form (if only to make sure I don’t forget how to do it).

Looking ahead

Looking ahead, of course, is all about the end to the pandemic, something that I have high hopes for. If I can get vaccinated by June, let’s say, then by July maybe I can resume normal activity (while wearing a mask and maintaining social distance, of course, but actually interacting with people other than just Jackie).

Normal would include hiking in the woods, and maybe visiting some natural areas within a few hours drive. (We’ve pretty much completely avoided going anywhere so far that we couldn’t go, hike, and return without having to use a restroom.)

Normal would include practicing parkour with the campus group.

Normal would include resuming teaching taiji in the fall.

I had scheduled a visit to Urbana Boulders to do some wall climbing right when the lockdown started, so that fell by the wayside. I had actually started taking an aikido class when we had to stop because of the pandemic. Either one of those things might happen, once the pandemic ends.

Basically, I have high hopes for 2021.

A few years ago I made a shift in my thinking about fitness—a shift from trying to get enough exercise to trying to fill my days with movement. I haven’t changed my mind about that being the right way to go, but this year, especially since the pandemic started, has seen me step back into exercise mode.

I still think movement trumps exercise. But during a pandemic the advantages of exercise have aligned better with my needs and my circumstances. (I’ve written previously about how our fitness room was closed and how I switched to working out with gymnastics rings instead.)

I have to say that it has turned out pretty well for me this year.

One thing about exercise is that it gives you a bunch of metrics you can track, and on the metrics I’ve done pretty well. At the beginning of the year I could do 3 pushups and now I can do 4 sets of 12. At the beginning of the year I could do zero pull ups, and now I can do a set of 3 followed by 2 sets of 2.

Having the metrics is great for someone like me who’s a big ol’ nerd about tracking that sort of data, but it’s not just a matter of numbers. Those bigger numbers correspond to real-world capabilities. I’m definitely stronger than I was at the beginning of the year, in all kinds of ways. I’m also leaner. (I have more muscle, plus I let myself lose about 5 pounds in a so-far vain effort to be able to see the abs I’ve built.)

A lot of my fitness goals are related to attaining and maintaining specific capabilities. I want to be able to:

  • Pick something heavy up off the ground
  • Take something heavy off a high shelf and lower it safely
  • Clamber on top of a wall
  • Jump down from a wall
  • Jump over a ditch
  • Run away from danger (or toward someone in need of help)

That’s not a comprehensive list; merely a brief sketch of the sort of things I want to be able to do.

Even a quick glance makes it clear that many of them are skill-based activities. I’ve worked on some of them before (click through the parkour tag to see six or seven years worth of reports about my efforts in those directions), but I felt that my efforts were limited by a lack of strength. That probably wasn’t even really true—parkour is scalable—but to the extent that it was true, it’s much less true now.

The way to get better at a skill-based activity is to practice it. And most of that practice should not be practicing whole activities, but rather individual pieces of them.

There’s a word that means practicing all the individual bits that go together to make a larger move: training—something that’s been really hard to do during the pandemic.

The real reason I’ve switched to exercise is that during the pandemic, although I’ve been able to move, my opportunities to train have been limited.

I’m hoping to spend the summer training. I’m thinking parkour, but if I can’t get it together to do that, maybe I’ll go with rock climbing. (Indoor climbing would be a great winter activity, if the vaccines roll out fast enough that I feel like it’s already safe to engage in indoor activity before summer weather. But there’s no rule against indoor climbing during the summer either.)

It’s possible to do parkour training during the winter, as long as it isn’t too icy. I tend not to get out in the cold or wet to do so, but I’m working on overcoming that—with some success: I’ve been doing pretty well at getting out for runs, even during chilly/damp fall weather. But I’m at the point where I could really use some instruction in parkour, and that’s out-of-bounds during the pandemic.

In the meantime, I’ll go on doing my exercise, figuring it’s the best way to get myself ready for training, once circumstances align.

I did an experiment a couple of days ago: I tested a combined workout that doubled up two pairs of exercises that I’d been doing separately. Up to now I’ve been doing four sessions each week: two where I do pull ups & pushups, and then two where I do dips & inverted rows. (Together with a leg exercise and a core exercise each workout.)

That was working very well, but it meant 4 upper-body strength sessions each week, which is a lot. Throw in a couple of lower-body strength sessions as well (such as hill sprints or kettlebell swings), plus a rest day, and I didn’t have a day to do anything else. This sort of volume has been well for me so far, but I think I may have reached a limit, and would benefit from a cycle of deeper recovery than just a week of lighter workouts: Except for “de-load” weeks in mid-March and mid-June, I’ve been averaging close to 5 workouts a week since the end of January. I’m thinking I want to take it down a notch.

With that in mind, I’ve been thinking about how I want to structure my training through the fall and winter. One obvious change was to go from four days of upper-body strength training per week to just three. The problem was that I didn’t see an easy way to evenly cover the range of pushing and pulling exercises at a reasonable volume with just three workouts a week, except by doing both pairs in each workout.

Hence my experiment, in which I did just that.

It was not a complete success. I managed to crank my way through the workout, but it was very long and tough. I don’t think I could keep it up three times a week for months.

Happily, while describing my difficulties to my friend Chuck, I had a brainstorm: I could do threes workouts per week—two of them just like what I’ve been doing (one with pull-ups & push-ups, and then another with inverted rows & dips), and then do just one combined workout. That keeps my workouts even, as far as covering all four exercises twice each week, without being quite so overwhelming as trying to do the combined workout three times a week.

With just three upper-body strength workouts per week, I have four days for other stuff, and I can mix and match as I choose. I can do the hill sprints that Anthony Arvanitakis recommends, or I can do kettlebell swings. (Either of those makes a good HIIT workout.) I can go for a run. I can go for a hike. I can do my animal moves. In particular, I can do two rest days, if that seems like a good idea. (Which I think it probably does. At least my Oura ring thinks so.)

This all got started back in February, when I figured out that I was lacking in consistency. (Previously I’d imagined that the problem was a lack of intensity.) Targeting 5 workouts a week has meant that, even when I miss one, I get in more than when I was targeting 3 workouts a week—even if I didn‘t miss one.

I don’t want to give up the consistency, I just want to take the volume down a notch. Hence the struggle. But I think now I’ve got a plan.

Gymnastic rings hanging from branch of sycamore tree, with a yoga mat in the foreground.

One side benefit to all the ring training I’ve been doing has been increased grip strength.

It hadn’t occurred to me in advance that this would happen, but it shouldn’t have been a surprise. Most people have poor grip strength (unless they either do manual labor, or else hang by their hands for some reason). Because most people start from a very low base, increased grip strength is easy to achieve.

Hanging exercises are a great idea for everyone. I encourage my taiji students to consider doing some sort of hanging exercise. They’re mostly seniors, so I admonish them not to actually hang by their hands without carefully working up to it, but just grasping something over your head, and then bending your knees to put a little weight on your hands will do a world of good for your shoulders. It will also start building grip strength. (In class I always joke that developing the ability to hang by your hands can save your life, if you unexpectedly find yourself in an action movie.)

I recently discovered that my grip strength had gone up in a way that was a little problematic: I was giving a dish rag a good squeeze, and found that it made my hand a little creaky: My grip strength was higher than it had been—enough higher to be out of balance with the strength of the joints and tendons in my hands.

There are two issues there. One is that grip strength for hanging from (or supporting yourself on) gymnastic rings covers a very narrow range of motion for the hands—the rings are just one diameter all the way around, and they don’t get smaller if you squeeze them, so you’re training your hands to be very strong in that one single position. The other is that muscles get stronger much faster than tendons do, so in a few weeks you can make your muscles strong enough that they can strain your tendons, while it takes months to make your tendons strong enough to stand up to the maximum force those muscles can exert.

After my experience with the dish rag, I got out my Power Putty. (It’s a brand of stuff like Silly Putty, but sold in a range of different stiffnesses. It’s marketed in the less-stiff versions to people who need physical therapy for some grip issue, and then in the more-stiff versions for people who want to build strongman-like grip strength.) I was a little surprised to find that the stuff I have—medium-firm—feels scarcely firm at all any more.

That’s okay. I’ve learned enough in the 20 years since I bought that stuff that I certainly don’t feel the need to get Power Putty in different stiffnesses.

The way to build further grip strength is to grip real-world things of a variety of sizes and textures. Squeezing dish rags is a great way to start. Hanging from tree branches (instead of just gymnastic rings) would be good too. Brachiating across monkey bars of various sizes will also be good. I’ve seen tricks for working on grip, such as putting a towel over a pull-up bar (or through a gymnastic ring) so that one hand is gripping the towel instead of the bar or ring.

Grip strength is strongly correlated with greater life expectancy (and superior health status in numerous other ways). This has to be one of the clearest cases ever where “training to the test” is useless—increasing your grip strength will not make you live longer—but living your life in a way that builds your grip strength is probably a great way to be stronger, healthier, more capable, and more comfortable as you age.

I think I’ll actually be using my Power Putty. It’s not really stiff enough to build my grip strength, but it’ll probably be just right to work on the tendons and joints in my hands. They mostly need time to get stronger to match the strength of my gripping muscles, but working them through a full range of motion will also help, and medium-stiff Power Putty will be great for that.
