The vastus medialis is involved in leg extensions.
The primary function of the knee extension muscle is to straighten the leg by extending the knee joint.
The leg extension exercise primarily targets the quadriceps muscle group in the front of the thigh.
Leg extension exercises focus on quadriceps.
The gluteus maximus is engaged eccentrically during hip extension when walking up stairs. This means the muscle is lengthening under tension to control the movement of the lower body and support the upward motion of the leg against gravity.
the quadriceps
Rectus femoris+ anterior thigh; quadriceps+ extension of leg at knee Vastus lateralis+ lateral anterior thigh; quadriceps+ extension of leg at knee Vastus Medialis+ medial anterior thigh; quadriceps+ extension of leg at knee Vastus intermedius+ deep anterior thigh; quadriceps+ extension of leg at knee Sartorius (*) parallel strap-like muscle that crosses thigh flexion of knee forward Biceps femoris* posterior thigh; hamstring* flexion of leg at knee Semitendinosus* posterior thigh; hamstring* flexion of leg at knee Semimembranosus* posterior thigh; hamstring* flexion of leg at knee
The neutralizer muscle of the leg extension is primarily the hamstring group, particularly the biceps femoris, semitendinosus, and semimembranosus. These muscles help to stabilize the knee and prevent excessive extension during the leg extension exercise, ensuring proper movement mechanics and joint safety. By counteracting the action of the quadriceps, they maintain balance and control throughout the motion.
Flexing the thigh, extending the leg, adducts leg
The leg curl and leg extension exercises strengthens two muscle groups. The two muscle groups are the hamstring muscles and the quads or quadricep muscles.

There are 3 types of muscle contraction in the leg extention and they are Concentric, Isometric, and Eccentric contractions.
Your leg muscles work together to help you walk up stairs.
