What Is Seated Leg Curl Hamstring Exercise?

The Seated Leg Curl is a targeted resistance exercise designed to strengthen the hamstrings, the muscles located on the back of the thighs. Typically performed using a leg curl machine, this exercise involves sitting on the machine with the back against a pad and the legs extended. The movement consists of bending the knees and bringing the lower legs toward the buttocks against resistance, engaging the hamstrings in a controlled manner. This exercise effectively isolates the hamstrings, promoting muscle development, strength, and flexibility in the posterior thigh muscles. It is a valuable addition to lower body workout routines and is particularly beneficial for individuals aiming to enhance the strength and stability of their hamstrings. Proper form and adjustment of the machine are essential for maximizing effectiveness and minimizing the risk of injury.

What Muscle Groups Are Targeted?

The Seated Leg Curl primarily targets the muscles of the hamstrings, which are a group of muscles located on the back of the thigh. The main muscles worked during the Seated Leg Curl include:

1. Biceps Femoris:
   • The biceps femoris is one of the major muscles of the hamstrings. It has two heads and is responsible for knee flexion.
2. Semitendinosus:
   • This muscle is one of the hamstring muscles and contributes to knee flexion and hip extension.
3. Semimembranosus:
   • Another hamstring muscle, the semimembranosus, assists in knee flexion and hip extension.

In addition to the hamstrings, the Seated Leg Curl also engages some secondary muscles, including:

• Gastrocnemius:
  • The gastrocnemius, part of the calf muscles, is involved to a lesser extent during knee flexion.
• Popliteus:
  • The popliteus is a small muscle behind the knee joint, assisting in unlocking the knee during the initial phase of flexion.

While the primary focus is on the hamstrings, the exercise involves the coordination of various muscles to perform the controlled movement of knee flexion against resistance. This makes it an effective isolation exercise for strengthening the hamstrings.
