Question

During a push-up, why does changing the hand position relative to the torso fundamentally shift the mechanical force applied to the chest and triceps?

Accepted Answer

Push-ups work your muscles by changing the angle of your joints. When you change where your hands sit on the floor, you change the path your elbows follow as you move. Imagine your arm is like a lever, which is just a bar that helps you lift things. If you place your hands wide apart, your elbows point out to the sides. This puts the most stress on your chest muscles because they have to work harder to pull your arms back toward your center. Think of this like trying to do a heavy bench press. When you move your hands closer together, your elbows stay tucked near your ribs. This forces your triceps, the muscles on the back of your upper arms, to do more of the heavy lifting. The movement becomes more like a push where your triceps handle the brunt of the work. By shifting your hands, you change the mechanical leverage, which is the amount of work each muscle group must provide to move your body weight against gravity.
