Be careful of shoulder injuries

As an older guy with plenty of life experiance and injuries, watch out for shoulder injuries. At one point in my life I was training hard towards a goal and doing hundreds of pushups a day. I injured my rotator cuff. The lesson learned for me is never go deep. If you go too low with your pishup to the point where your upper arm (Humorous) goes beyond paralell to the floor, you are straining your shoulder. It's kind of counter intuitive but the same goes for bench press. Just keep your upper arm paralell with the floor and next to your body, never behind you. keep your elbow pointing at your feet and never let your elbow point any farther rearward than that. Good luck!
