What’s up with all this kipping nonsense?
In general, we are not as concerned with developing specific muscles as much as we are with developing efficiency in specific movements. A kipping pull-up might be easier on the bicep than a strict pull-up, but we’re not necessarily concerned with isolating development of the bicep. Instead, we are concerned with developing one’s ability to pull to a particular point. From this perspective, we believe that the kip has its place in number of different movements. That said, we also believe that the kip is an advanced movement and should be developed only after developing the strict version of the given movement.
