Question: 1 / 400

Which muscles are used to globally stabilize the humerus during the bench press?

Triceps brachii and biceps brachii

Latissimus dorsi and deltoid

The latissimus dorsi and deltoid play significant roles in stabilizing the humerus during the bench press, which involves pressing movements that require a stable shoulder joint.

The latissimus dorsi, a large muscle of the back, aids in stabilizing the shoulder by anchoring the humerus to the scapula. Its involvement ensures that the upper body remains stable, allowing for effective force transfer during the pressing motion. The deltoid, which covers the shoulder, contributes to the abduction and stabilization of the arm, particularly during the lifting motion involved in the bench press.

Together, these muscles help maintain the proper positioning of the humerus in the shoulder socket, reducing the risk of injury and ensuring optimal performance during the exercise. This stabilization is crucial, as any instability can lead to improper mechanics and potential injury while pushing heavy weights.
