Shaun is the Man !! My favorite trainer buddy fixed my busted collarboneShaun is the Man My favorite trainer buddy fixed my busted collarbone by having me do every angle of pushup ever I had to work from sternum to armpit and I finally got that right shoulder of mine to quit slipping out and being dislocated (old downhill racing injury) SO girls and Women should do pushups You won't go down a bra size if you keep eating deserts.. I went down a cup size but I don't care I'm the strongest I have ever been and I hope this busted collarbone never gets broken again. But if it does I know what to do.... http://www.health.com/fitness/this-50-push-up-challenge-will-transform-your-body-in-30-days https://www.amazon.com/Push-up-Progression-Workout-Stronger-Core/dp/1619841843
