As some of you probably know from previous thread I can't lift at the moment so I'm going to do cardio sessions and abs until my injury is better. I started today doing cardio first thing in morning on empty stomach. My question is would it be ok to do cardio in the evening as well. What I mean is by doing 2 cardio sessions is it going to eat away more muscle while I can't lift and would you all stick to just in the morning instead of at night. Also to keep muscle from losing by doing cardio and the catobolic break down is it better to do it at lower intensities for longer periods of time, also what supplements helps for anti-catabolic break down besides calcium and vitamin C. THanks as always
