Leg Curl Exercise Guide for Strong Hamstrings

The leg curl is an isolation exercise that primarily targets the hamstring muscles located at the back of the thighs. It is commonly performed using a lying leg curl machine, seated leg curl machine, or standing leg curl machine. This exercise focuses on controlled knee flexion to strengthen and shape the hamstrings.

How to Perform the Leg Curl (Step-by-Step Technique)

1. Machine Setup

Adjust the machine so the ankle pad rests just above your heels. Ensure your knees align with the pivot point of the machine for safe and effective movement.

2. Starting Position

Lie face down or sit upright depending on the machine type. Grip the handles firmly, keep your core engaged, and maintain a neutral spine.

3. Curling Movement

Exhale and slowly curl your legs upward by bending at the knees. Focus on squeezing your hamstrings at the top of the movement.

4. Controlled Return

Inhale and lower the weight slowly back to the starting position. Avoid locking out your knees to maintain constant muscle tension.

5. Breathing and Tempo

Use a controlled tempo with smooth breathing to maximize muscle activation and reduce injury risk.
