Which is a better way to exercise?
I have been reading a lot about building mucsle and losing fat. On the one hand I have read to only work 1 muscle one day a week, ie abs/legs day1, shoulders/chest/triceps, day 2, biceps/traps/back day 3, Days being MON WED and FRI. This also includes eating right and eating more calories in a day than I expend inorder to build a lot of muscle. On the other hand I have read to work out MON WED and FRI, but do the same exercise each day so each day I would work legs/abs/biceps/triceps/shoulders/back, the exercise of which could take 1.5-2.5 hours. The first exercise plan has to take less than an hour each day. As I read if after 45min of working out the muscles have been fully stimulated and any longer working out will only decrease the work you have already done. I guess my real questions are is it better to work only a mucsle only once a week or more than once, should the work out be less than and hour or is more okay, and should I eat less or more calories than I expend.
What is the best way to build muscle and either lose or replace the fat?
I have also heard of doing 5 days of exercise where MON WED FRI are weight training,splitting up the muscle groups to only exercise a specific muscle once a week and then on TUES and THURS do cardio like an hour of running or an hour of rowing.
