Question: 1 / 400

Which major muscle groups are primarily involved in a squat?

Quadriceps, hamstrings, gluteus maximus, and calves

The primary muscle groups involved in a squat include the quadriceps, hamstrings, gluteus maximus, and calves. This exercise primarily targets the lower body, making it an effective way to build strength and stability.

The quadriceps are located at the front of the thigh and are responsible for extending the knee, which is a key movement in the squat. The hamstrings, positioned at the back of the thigh, assist in knee flexion and hip extension, complementing the actions of the quadriceps. The gluteus maximus, being the largest muscle in the body, plays a crucial role in hip extension and maintaining proper posture during the squat.

Additionally, the calves contribute to stabilization and help with plantar flexion during the lift. Engaging these muscle groups effectively promotes overall strength development in the lower body, making option A the correct response.
