Hi, I've been reading a bit about weight training recently - so depending on how much you stress your muscles and their size, you can expect to rest longer the bigger they are etc. How does weight tranining fit into the equation with respect to "normal" training, when you hear athletes doing workout 5-6 times (maybe more) a week 2-3 times a day. How do they workout so much and avoid overtraining? I'm interested in this because I do weight training every 2nd day and my program only takes 40-50 min. The rest of the time I do nothing... Did I miss something? Thanks Oh I do play tennis 2-3 times a week for 1-2 hours, but from next month I won't be able to, so I really want to do some more workout... Actually let me formulate an easy question: "Can I do cardio (or just practice tennis) when i'm resting/recovering from weight training?"
