Which muscles are considered the primary muscles involved during a lunge?

During a lunge, the primary muscles that are engaged include the gluteal group and the quadriceps, making the chosen answer correct.

When performing a lunge, the gluteal muscles are crucial for extending the hip as you push off from the ground and return to the starting position. The quadriceps are vital for extending the knee of the front leg, providing stability and strength as the body lowers and rises.

While other muscles may contribute to the movement—such as the adductors helping to stabilize the legs or providing additional support in maintaining balance—the main function of the lunge primarily revolves around the hip and knee extension, which are driven by the gluteal and quadricep muscles.

This option is particularly insightful because it highlights the importance of both muscle groups in achieving the goals of the exercise effectively.
