Most Chinese styles use a relaxed approach to power development. We try to keep unnecessary muscles from being involved in the technique, in order to avoid inhibiting the prime movers behind a certain technique from doing their job. Essentially, a straight punch is a tricepsdriven technique and the Chinese style of punching allows the triceps to do its job without the inhibition of significant biceps involvement in this punch..I noticed recently that Morkel was bowling at 137142 (didn't bowl a ball faster than 142 in the couple of tests he played against Pakistan) Mike Hazelman was calling him "Really rapid" and repeatedly saying stuff like "That's like a bolt of lightning" at balls registering between 135 and 138kph which is what the vast majority of Morkel's balls were according to the speed gun there. Not sure speed is as important as people make out. Otherwise Irfan and Tate would be the best test bowlers today and McGrath would have been a trundler at best.
