I asked this question on the injury/rehab board but didn't know if it would be more appropriate here. Either way, I'm sure some of you guys can shed some light on this. My question is...
Is it just as easy to tear a muscle doing light weight/high reps as opposed to heavy weight/low reps?
As some of you know I completely tore my pectoralis muscle in late March and had it surgically repaired May 9. My Doctor said that when I go back to lifting in August I should never do heavy weight on the bench press ever again. He said I'm more likely to retair this if I do heavy weight/low reps (>6). He recomended I do light weight/high reps (12-15) that way it has less of a chance at retairing and he said that rep scheme is good at building muscle, increasing muscular endurance, and would be good for strengthening my surgically repaired pectoralis muscle/tendon.
My question is, is my Doctor wrong? Is it just as easy to tear a muscle doing light weight/high reps as opposed to heavy weight/low reps?
One more question, can I build big strong muscles doing reps of 12-15 for all my lifts? Or do I have to go heavy (>6 reps) to acheive this?
