I have a schedule on my refrigerator of what muscle groups I'm training each day. My workouts cover two body parts except for legs, which get a complete training session dedicated to them. But I continue to wonder if I'm giving too much rest to each group. adding in a session for ab work, cardio, and some exercises that are not the basics, what I call "secondary, very specific" (like forearm work and inner-outer quad work) . Each muscle group gets about 5 days rest before I hit it again. I'm feeling good and in good overall shape, but am beginning to think it's too many days before I hit a muscle group again, and could probably get away with 4 days rest for a muscle group.
Guys--your thoughts and experiences, please...
