When you say 4-6 sets per muscle, how did that work? The back is considered a muscle group yet has much more going on than biceps or triceps. You have back erectors, muscles to pull the arm back (upper back) and pull elbows down (lats, the "width" muscles.) I like to do deads, something for upper back, then something for lats/width. Should each get its own 4-6 or is that to be the total back workout? Thanks.
I think it's not how many. I think it's the last three.
1. Your brain telling you there isn't much left in the bucket.
2. You ask your brain am I really done or can I do one more?
3 You do one last rep and trully fail the muscle.
This sends a message " I'm asking more of you than you can provide", a message of change.
Arnold was quoted saying that he "willed" his muscles to grow. Mike Mentzer said he would visualize his worst enemy holding a loaded gun to his head, at the end of a set, and that if he didn't get a few more reps he'd pull the trigger.
These sayings have always stuck with me and come to mind whenever I'm about to end the set. This mind F'ing yourself actually works.
Big difference between maintaining a physique and adding quality muscle every year.
