I recently read a thread on this site that extolled the virtues of the proper pushup form. It led me to wonder about the "kipping" I see on alot of the exercise demo's. Does performing the kip do something else besides allowing the participant to complete more repetitions? Isn't the dead hang pullup the "proper form?" thanks.

This has been covered in much depth here on the boards.

From the FAQ: 2.14
http://www.crossfit.com/cf-info/faq.html#Exercises13

"There are a TON of discussions about this on the boards. Try searching for kipping and kipping pull-up via the search function. There is also an entire Crossfit journal dedicated to the kipping pullup. "if you'll read this thread on the kipping pull-up I think you'll come to see the move in a different light. It's a long read (10 pages or so) but well worth the effort. I've never seen more thoughtful or complete analysis on the movement anywhere: http://www.crossfit.com/cgi-bin/disc...=22&post=34589
NOTE:Greg's famous quote, "We do your stuff nearly as well as you do, you can't do ours very well at all, and we do everything that we both don't do much better than you can. Not very humble, I know, but true." first appeared in that thread, Here.

"Short version: Kipping allows more work to be done in less time, thus increasing power output. It is also a full-body coordination movement when performed correctly, which applies more functionally to real-life application of pulling skills. Last, but not least, the hip motion of an effective kip mirrors the motion of the olympic lifts/kettlebell swings, adding to it's function as a posterior-chain developer."

Do some box jumps, 20-30 inches high. Pay careful attention to how you move.


As you jump, you're going to swing your arms, unless you actively fight it. The momentum from the arm swing takes some of the weight off the legs when you push off to jump. In this, you do the same amount of work, because you move your bodyweight the same height upward. However, you spread the load out, allowing you to jump up faster and with a higher turn-over, increasing your power output.


If you use your arms to help you jump, why not use your legs to help you pull?
