Advantages of both? Disadvantages? The place I box at right now is only an hour long class, 4-5 times a week. Its taught by an ex-pro, but all it is is just working combos on focus mitts. However, I've been using this preciously short time to get in sparring rounds instead. Gonna need to setup something in my garage if I want to train any harder. Plan on putting in a heavy bag, speed bad, and double end bag.
