Hey,
Quick comment/question. Lets pick three exercises that primarily work the chest...Flat bench press, incline bench dumbbells, and dips (leaning forward, of course). Each of these hit a slightly different angle and I think work well together.
Now, the question: Would it be better to do all 3 of these in one workout (3x1), or would it be better to do one of these exercises (i.e. bench press) until chest is completely cooked, then do exercise #2 NEXT WEEK (i.e. incline dumbbells) and so on. (1x3)
The reason I ask is because I see a lot of routines that have people running all around the place doing 3, 4, & 5 exercises in one workout for one muscle group. My theory is that if you do a really good job on the first 1 or 2 exercises, the later ones for the same muscle group in the same workout are going to be weak.
Now of course with the many-exercise-per-workout method, you could rotate the order of exercises week to week so you start with different ones (i.e. bench, incline, dips week 1...incline, dips, bench week 2...dips, bench, incline week 3...) so that no one exercise gets all the beginning energy.
Do the workouts of 3, 4, and 5+ exercises for a single muscle group have any synergistic effect I might be missing? I hope I did alright explaining here.
