"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."
