What I mean by the title is, which muscle's should you work out with other muscle's. For example, is it a good idea to work out the bicep and tricep on the same day (same workout) or perhaps do bicep and back on same day, etc. All this based on working out 5 days a week. Main muscle's/groups I am concerned about is: bicep, tricep, upper and lower back, abs, forearm, legs - both quads and calves.
The point of this is I am trying to make a new plan and I know I've heard that it is better to work some muscle groups out on the same workout and your workout will be more efficient. By this I am also going by only working out maybe 2-4 muscle's in one workout lasting from 1 hour to hour and a half.
