How to do better pushups
Position your arms correctly.
No matter your push-up style, start by placing your hands shoulder width apart. Stack your joints for the best stability.

(b). Position your torso so that your heels are parallel but slightly bent over the outside of your feet, or you may be rocking a bit more than they should be. As you do so, get into a squatting position.;
(c). Place your palms on your restive wall or a wall. In order to put up the challenge, you'll want to increase your body's non-restive ability.;
(d). Your hands should line up under your elbows and your elbows should be underneath your shoulders. Stacking your joints helps to prevent damaged rotator cuffs and other injuries.;
