RE: If you have to do strength training and aerobics back to back, of which do you find the best results?(I've heard many different things on this-has Cathe provided feedback on this yet?)
I prefer cardio first because otherwise you need to do a cardio warm up, then weights, then back to cardio which takes more time.
Also, I find cardio (with videos) more fun, and I just don't enjoy it if I am tired from weights, especially if I did weights for legs.
