Like peanut butter to jelly, like ham to hamburger… the kipping pull up is to CrossFit
From the CrossFit Journal on Kipping pull ups, “Kipping comes in a myriad of styles, and each athlete has a signature kip, but in its most elegant form the kip is a transference of movement first generated in the horizontal plane, where it comes cheap and easy, to the vertical plane, where momentum and a perfectly timed pull from the back launch the athlete forcefully upward. “
CrossFit games competitor Jason Khalipa explains the kipping pull up.
