The quadriceps include four muscles that run from the femur down to the tibia and fibula, or the leg bones. The quadriceps are knee extensors so they straighten your knees. Squats target the quadriceps when you raise your torso up.
Standing Phase: Muscle Activation. Muscles activated in the standing phase of the squat are the same muscles that are used in the lowering phase. However, during the standing phase of the squat, these muscles shorten as they contract, producing a concentric contraction.s you lower into a squat, these muscles contract as they lengthen to control your speed. The knee extensors -- rectus femoris, vastus medialis, vastus intermedius and vastus lateralis -- contract as they lengthen to control your knees as they bend.
