Which of the following best describes the primary focus of a push-up?

The primary focus of a push-up is to lower the body to the ground while keeping it in a straight line. This movement primarily targets the chest, shoulders, and triceps while also engaging the core and stabilizing muscles. Maintaining a straight line from head to heels is crucial, as it ensures proper form and maximizes the effectiveness of the exercise. When performed correctly, the push-up effectively strengthens the upper body and core, providing a solid foundation for overall functional strength and fitness.

In contrast, using a wide grip can change the emphasis on certain muscles but is not the primary focus of the push-up itself. Rapidly bending the elbows might compromise form and lead to injury rather than effectively working the intended muscle groups. Relying solely on leg strength during a push-up does not align with the primary mechanics of the movement; it is an upper body exercise that requires arm and core engagement rather than focusing on leg strength.
