Which muscle group is primarily engaged during a squat?

The primary muscle group engaged during a squat is the quadriceps. These muscles, located at the front of the thigh, play a crucial role in extending the knee joint as you rise from the squatting position. When you perform a squat, the quadriceps are heavily recruited to lift the body back to a standing position after lowering into the squat.

While the other muscle groups contribute to the overall movement—hamstrings assist in stabilizing the hips and knees, the glutes help in hip extension, and the calves support stability and balance—the primary focus during a squat is indeed the quadriceps. This exercise is particularly effective at targeting and strengthening the quadriceps, making them the most engaged muscle group throughout the movement.
