Thoughts while Pedaling... learning without pain

How do you feel when you learned something new? Feels pretty good doesn't it… Well what I’m about to tell you felt better than good and Actually saved my shoulders and my rotator cuff… I was doing my 20 push-ups just a warm-up at the gym and a gentleman came up to me and said you are going to destroy your your shoulder, now please pass this one to your kids... Never do a push-up all the way to the ground only do a 90° angle with your arm to your back shoulder Even doing 20 push-ups can dislocate your shoulder if you are off by one measurement And I have to admit I have been having some shoulder soreness after going all the way to the floor.
