I went out a made a short video of some of the stuff I trained today and was wondering if you guys could help.  I recently got climbups down with somewhat okay form.  After 2 years of thinking it was a strength issue, it turned out to be form.  I know my upper body isn't terribly strong, 3 bouts of tendinitis in my shoulder in the past 3 years from other sports took away a lot of strength, but anyone can make excuses I guess.  1:27-1:41 is where a couple climbups are.  Besides the need for some more conditioning, some of the stuff I've noticed is my left leg tends to flail/kick out awkwardly and I sink down a little when my hands first land on top.  Oh, and on the last one my feet aren't staggered as much as they should be, but I think I actually got a little more of a push than on the others.  Anything you guys can offer to help my tall lanky self look less awkward would be very appreciated.

rail precisions were pretty tight... you stuck them too    As for climb up, really think explosive... no real need to hang in cat position... just continue movement.

nice video! im lovin the vide.  two big problems i saw  your pulling your body into and over the wall (this usually means you lack lat strength and explosive pulling strength in general) and your feet are too far under your body ( if you raise them up a bit, especially your top foot, you get more traction on the wall because more surface of your foot is on the wall).    all you need to do is raise those feet and work on your pull-ups with a full range of motion all the way down and all the way up with focus on pulling up as fast as possible and lowering down nice and controlled. this will give you the strenght to pop up and away from the wall    i <3 climb-ups

Just in case you haven't seen this yet, this video helped me in the past.

Climbups and 180s and MUG

Chris covered most of the basics: Pull your chest up, not in; keep your feet high; and working on explosive strength with full ROM.

Another thing that I might add is that you  should actually use your left leg to engage in the climb.  Rather than letting your foot flail behind you, try to step into the wall to get some extra power.  If you watch Teige's technique, you'll see that he actually takes a step onto the wall to get extra power during both his climb ups and his 180s.  This should give you a bit more push, but you'll have to play with it until it feels right.

Thanks for the tip!  But I do think whether you top out with both feet on the wall or with one foot while swinging the other through is all based on preference and the situation. They're both similar speed wise.  The only advantage I can really see to both feet is if you were to precision directly after your climbup.  I can do both, but I definitely feel like I think about it a lot less when I do the one foot thing.  I do have to keep drilling the other one though, so thanks for the reminder.

As for the arms being unequal, I'm not sure what you're referring to.  At the end of the climbing part I went one arm at a time because I'm not a huge fan of heights and that felt a lot safer, but during the part where I was drilling just the climbups I didn't think I was, was I?  It's hard to tell from the video, but I didn't feel like I was.

repetition isn't always the answer.  on something as technical as climbups repetition may only inforce bad technique.  it is sometimes best to break it up into sections and strengthen them one at a time before repeating the whole thing over and over.
