The quadriceps, or front thighs, serve to straighten the leg at the knee. This group is worked when straightening the leg at the knee.

Quad Exercises

Squats, leg presses, and leg extensions are by far the most common workouts used to develop the quadriceps. All of these exercises are usually weighted, as the quadriceps are exceptionally strong (relative to other voluntary muscles such as the arms). The motion for them involves repeatedly bending the knees in unison to the torso and realigning them.

The squat is done from a standing position, where weight is applied to the back at the shoulders. The torso is lowered to the knees and uses a standing motion to straighten them back.
