I started a new work out program to get rid of my moobs, I started doing 10 push-ups (I hate the burning soreness I get when I jump in whole hog) and added 1 push up each day after that. I'm up to 30 push-ups now and my shoulders are getting really sore. My right shoulder was injured when I slipped and fell on some ice a few years ago, if it was sore I wouldn't be too concerned, but my left shoulder is the one that is sore and it's never been injured. It's a joint pain, it hurts when I push on something in certain directions with moderate force, again this is not muscle soreness from exercise, it's joint pain. I'm 32 years old, 6'2 about 170lbs, I am fairly active, I exercise for 4-5 hours per week, but most of my activity is walking/hiking or cycling. I have a history of joint and bone problems on my mother's side, I'm concerned that I may be predisposed to the same problems my mother has, although her problems didn't start until she was into her late 40's. I'd rather have soft, sexy moobs than live with pain in my shoulders for the rest of my life, but if there's something I can do differently in my exercise and not have pain or moobs I'd rather go that route. Is there something wrong with my technique when I do push-ups? I spread my hands about twice my shoulder width on the floor and lower my body until my elbows form a right angle, then push up, it's how I was taught to do push-ups in junior high school.
