[Exercise] Kipping pull-up [Notes] 
A somewhat controversial exercise the kipping pull-up variation is a CrossFit favourite and involves the use of the legs to help with the movement, in contrast to a strict pull-up where the lower body remains engaged and static. The legs are swung backwards to build momentum, and forcefully swung forward while pulling the body up with the arms.
