Quadriceps
Squats are one of the best, if not the best, exercises you can do. This is because they work so many muscles, while forcing you to stabilize and balance your body under a heavy load. The primary muscles involved are the quadriceps, hamstrings, glutes, and adductors.
No, the hamstring is posterior to the quadriceps.
hamstrings and the quadriceps
Hamstrings and Quadriceps.
The hamstrings straighten the knee, while the quadriceps (on the front of your thighs) bend it.
In the thigh, the quadriceps and hamstrings work in opposition to bend and straighten the knee. The quadriceps, located at the front of the thigh, contract to extend the knee, while the hamstrings, located at the back, contract to flex the knee. This coordinated action allows for smooth movement, with the quadriceps providing stability and strength during extension and the hamstrings facilitating bending. Together, they ensure efficient knee function during activities like walking, running, and jumping.
The quadriceps are primarily innervated by the femoral nerve, which provides motor function to this muscle group. In contrast, the hamstrings are predominantly innervated by the sciatic nerve, specifically its tibial and common fibular branches. These nerves play crucial roles in the extension of the knee (quadriceps) and the flexion of the knee and extension of the hip (hamstrings).

When performing the lateral step-up, you will be using the quadriceps and knees, glutes and hips, and hamstrings. Most of the lower body will benefit from this exercise.
Your quadriceps, hamstrings, calf muscles, hip flexors, lower back, lower abdominals, and your glutes are worked doing lunges. Your quadriceps, hamstrings, and glutes are the main muscles worked, the rest are secondary.
It helps exercise the quadriceps (top of thighs) and hamstrings (back of thighs).
