If you are a beginner and want to build as much muscle mass as possible in the shortest possible time, I suggest you train 5 days per week. You start with a 2-day split routine and work yourself up to a 5-day split program as your body gets in better condition. Use each split routine for a minimum of 4 to 6 months before you move to the next split level.
If you have never trained with weights before, I suggest you start the first 6 months with a 2-day split routine in which you train half of your muscles during the first workout and the other muscles in the second workout. You should do a couple of basic exercises for each muscle group and perform 3 sets per exercise. The first set should be a warm-up set for which you use light weights and do about 20 repetitions. Each rep should be performed slowly (about 3 seconds) and you should focus on your technique. For the 2 next working sets you use heavier weights so that you can perform about 10 quality reps per set using perfect form. Each workout should take less than 80 minutes to complete.
After about 6 months using the 2-day split your body should be ready for a 3-day split routine. By splitting your training over 3 workout days, you have some extra time to add a couple of exercises or to do an extra set for a few exercises. Do for each exercise at least 3 working sets of 8 to 12 quality reps per set. Each workout should take maximum 70 minutes to complete.
After about 6 months using the 3-day split your body should be ready for a 4-day split routine. By splitting your training routine over 4 workout days, you have some extra time to add a couple of exercises or to do an extra set for a few exercises. Do for each exercise 3 or 4 working sets of 8 to 12 quality reps per set. Each workout should take about 60 minutes to complete.
After about 6 months using the 4-day split your body should be ready for a 5-day split routine in which each muscle group is trained exactly once per week. By splitting your training over 5 workout days per week, you can train each muscle with maximum intensity and provide them enough time to completely recover and grow before their next training. Do for each exercise 4 working sets of 8 to 12 quality reps to failure. Each workout should take maximum 60 minutes to complete.
