Question: 1 / 445

Which muscle is considered the prime mover in a push-up?

Pectoralis minor

Pectoralis major

The pectoralis major is considered the prime mover in a push-up because it is primarily responsible for the movement of the upper arm during the exercise. As you perform a push-up, the pectoralis major contracts to bring your body up from the ground, effectively pushing against gravity. This muscle is large and powerful, which allows it to generate the force required to lift the body.

While the other muscles listed play supporting roles in a push-up, none are the primary movers. The pectoralis minor assists to some extent, but it is the major muscle that primarily drives the movement. The rhomboids help to stabilize the shoulder blades, and the rectus abdominis contributes to core stability, engaging to keep the body in a straight plank position. However, it's the strong contraction of the pectoralis major that facilitates the actual pushing action of a push-up.
