1) Soreness is not a sign of a good workout so you're not necessarily doing anything wrong. 2) I have no way to tell you if you're doing something wrong without knowing your diet/workout plan/how much you're lifting/why you're spending 2 hours a day in the gym. 3) If you're genuinely interested in getting in shape I can hook you up w/ a diet & workout plan for cheap. @ Priest, you're not in air performing your katas. You're on the ground where there is a stronger body weight resistance thanks to gravity than there is in the water. Why you ask? Because your body is submerged in water and thus part of the resistance is suspended. This would not be the case however if you're in a very shallow body of water. (That would be the only scenario in which anything you're claiming would make sense). Regardless of which, it's the summer who wouldn't want to be in the water.
