I’ve been working on dips for a while, but not with great consistency until just the past three or four months.
For a long time I was doing bench dips (where you put your hands behind you on a bench, stretch your legs out in front of you with your heels on the floor, and then push with your hands to raise your hips up to the level of the bench), to try to get my triceps strong enough to do real dips. In the fitness room there are some bars that can be put on the squat rack so you can do bar dips. I wasn’t really strong enough to do a good bar dip, but I’d sometimes do partials or negatives.
For parkour, you want to do wall dips, but I don’t know of any good chest-high walls in Savoy, so I haven’t practiced those in a long time.
Since I got my gymnastic rings around the end of March, I’ve been working pretty steadily on ring dips. (Which are much harder, because while pushing yourself up you also have to be able to stabilize your body.)
I’ve been following pretty much the usual progression—working on just a ring support (where you hold yourself in the top position for a dip), on negative dips (where you just lower yourself), and on partial dips (where you lower yourself only part of the way down, and then back up).
I’ve been gradually increasing the range of my partials, and a few days ago I thought I was doing a full, proper dip. I wasn’t really sure though—there aren’t any mirrors out under the sycamore tree where I hang my rings. So today I got Jackie to come and video me, so I could watch what I was doing:
I think those first two—especially the second—are legit dips. (The third, of course, is just a negative.)
