One caution, Smileless - I don't know if you knew this, but if you're doing weight training, you should not be exercising the same muscles two days in a row. Weight training causes tiny tears in the muscle, which are then repaired and the muscle increases in size. This is quite normal. But it takes a couple of days to do that. You can train with weights several days a week, just not the same muscles two days in a row. I used to follow an exercise regime that had me working out 5 days a week. Four days of weight training (one day chest, triceps, and squats, the next day back, biceps, and lunges; also had some abs work thrown in each day) and a day of cardio.
