In the world of martial arts, there are countless legends about past masters and their feats of internal strength. These legends run from the believable (poking a hole through a wall with just a finger), to the eyebrow-raising (killing a horse with a gentle pat on the back), to the hard-to-swallow (striking someone from 30 feet using only Qi). There are endless debates about internal strength. Some people believe in it, some people don’t, and some are on the fence.
