Tomorrow I'm going to add additional training to what I'm doing with boxing. I've designed a program that gives me benefits for fat-burning, cardio, increased muscle, and imbalance correction. It's very tough to do all those at once so there are focuses for sure. While I always want to increase muscle mass I'm doing it in functional sort of way. At the onset of a program and coming off a multi-year injury, just about anything I do will lead to a muscle mass increase as long as my nutrition and recovery is adequate. I'm only going to do a few sets of everything, at moderate intensity, to see how things hold up. Over a few weeks I'll ramp it up as I'm able. My real goal here is to achieve a sustainable level of health. That includes a reality bodyfat %, good eating habits, and a level of cardiovascular fitness. One very important component of this is boxing, and I'll do those workouts in addition to these other sessions.
