I agree. going heavy is not good. I suffered a light tear in my inner left peck awhile back (about 5 months ago) and I took a few months off(about 2). When I started back up I did just push-ups for about a month, then slowly incorporated heavyer weight into the process. Im now just starting to get back into the 100lb dumbbell range for 3sets/10reps 2-3x's a week(I currently weigh 160lbs). But Ive allso been shoveling in 10-15grams of creatine the past 7 months(which I think helped me recover & get my strength up quicker).
