My muscles can handle the heavy weight but it doesn't look like my joints can... I was going for 405 on bench again and hurt something in my right shoulder. its about impossible to do flat bench or military presses.. dumbells hurt but not as bad as using a bar...... im getting ready to go to the doc. wish me luck. a buddy of mine had this same thing happen about a year ago and still can't flat bench to this day!
