Is there such I thing? I don't recall ever hearing about it. Is there some sort of minimum reps/set scheme you could devise to maintain size and strength? Right now I work out 45-60 minutes about 'two days on, one day off', or so. But in the summer time I will most definitely be busier. Not only that but I wouldn't mind if I could somehow get away with 30 minutes lifting, 30 minutes cardio while still preserving my muscle and strength. Anybody know what would help? Maybe some good full body routines? Or splitting my body upper and lower half?
