The leg extension exercise primarily targets the quadriceps muscle group in the front of the thigh.
Leg extension exercises focus on quadriceps.

The primary function of the knee extension muscle is to straighten the leg by extending the knee joint.
The vastus medialis is involved in leg extensions.
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.
A fixator for a leg extension exercise is a piece of equipment that helps stabilize and secure the leg during the movement, typically found in a leg extension machine. It is designed to isolate the quadriceps muscles by restricting movement in the hip and knee joints, allowing for more targeted muscle engagement and better form. Fixators can help enhance the effectiveness and safety of leg extension exercises by providing proper support for the legs.
The concentric part of a leg extension occurs when the quadriceps muscles contract to lift the lower leg away from the starting position, straightening the knee. This phase involves actively shortening the muscle fibers as resistance is overcome, typically when the weight is being pushed upward. It is essential for building strength and muscle mass in the quadriceps.

The main difference between a sissy squat and a leg extension exercise is the muscle groups they target. Sissy squats primarily work the quadriceps and engage the core for stability, while leg extensions isolate the quadriceps without engaging other muscle groups as much. Additionally, sissy squats require more balance and coordination compared to leg extensions.
