Which muscle group is primarily targeted during the Leg Press Standing exercise?

The Leg Press Standing exercise primarily targets the quadriceps, which are the muscles located on the front of the thigh. When executing this exercise, the primary movement involves extending the knee, which is primarily accomplished by the quadriceps.

While other muscle groups, such as the hamstrings, calves, and glutes, may be engaged to some extent during the exercise, the most significant work and emphasis are placed on the quadriceps. The hamstrings are involved in stabilizing the movement and assisting with hip extension, but they do not play as dominant a role as the quadriceps. The calves are involved in ankle stabilization, and the glutes contribute to hip stability and extension, yet they are secondary to the primary action of knee extension. Therefore, the correct association with the Leg Press Standing exercise focuses on the quadriceps as the primary targeted muscle group.
