“Just pushing your body weight is super effective,” Romero says. The exercise is perfect for those looking to strengthen their upper body in a simple way. Beginners like it because it’s fairly easy to learn, but also easy to mess up. Don’t do it if you have shoulder or wrist injuries. Hands should be placed close to the sides of the body (shoulder-width distance apart) and directly below the shoulder, with fingertips pointing forward. Engage the core by squeezing the abs and glutes.
