Your floor is not a gym bench. A hard floor forces your shoulders to absorb all the shock with zero shock absorption. Pro tip: Do push-ups on a yoga mat or even a folded towel. It’s like putting a pillow under a baby crying in a car seat—it doesn’t fix the problem, but everyone feels better.
Also, surprising fact #2: Your wrist angle matters more than you think. If your wrists are bent back like a flamingo’s leg, it locks up your forearm muscles, which in turn pulls on your shoulder. Try making fists or using push-up handles. Your wrist will whisper sweet nothings of relief.
