I am curious how much weight everyone lifts when it comes to shoulder excerises. I do alot of dumbell exercises for my shoulders and find that I get tendonitis when I do too much weight. I wonder if I am over ambitious with my lifts. I do arnold presses, db press, military, bent over flies, and shrugs but the only two exercises that hurt are the two presses. I do 3 sets of 6-8 with 55 lbs dumbells. My shoulders are my weakest link and have given me problems for some time. I am 5'8" and 185 lbs so, I'm not the biggest guy but when I look at Ironman or Muscle Mag, the bodybuilders are usually only pressing with 40's or 45's. Let me know what you all suggest.
