Martial Arts training can manifest itself into almost any fashion. It can be stretching movements to power building exercises. The one thing I have never seen in martial arts is the use of a sledgehammer. This video uses a sledgehammer to build forearm strength for different uses in Kung Fu. Some of these exercises look great and some look down right dangerous. Please proceed with some caution for all you adventurous individuals but do incorporate some of the concepts into what you do. We can all benefit from stronger forearms.
