You don't want to work out the same muscle group every day. Also workouts can involve not only primary muscle group but secondary muscle groups, i.e. bench press works chest but secondary muscles affected are front deltoids (shoulder) and triceps.
When I use to work out (I am not an expert, certified, maybe certifiable) I would try to work out 5 days a week. Week 1 I would work certain muscle groups M, W, F and different groups on T, Th. Week 2 muscle gourps I did last T, Th would be M, W, F and switch week 1 M, W, F, muscles to T, Th. example:
Week 1
M, W, F
*chest, shoulders, triceps, Abs
T, Th
* back, biceps, legs, Abs
Week 2
M, W, F
* back, biceps, legs, abs
T, Th
* chest, shoulders, triceps, abs
Anybody that is more up to date can probably help out more. I am surprised more peolpe have not responeded yet.
