Hamstring curls are an exercise designed to strengthen the muscles at the back of the thigh, known as the hamstrings. This exercise can be performed using various equipment, such as a leg curl machine, resistance bands, or even body weight. The movement involves bending the knee to bring the heel toward the buttocks, effectively targeting the hamstring muscles. Incorporating hamstring curls into a fitness routine can improve overall leg strength, enhance athletic performance, and reduce the risk of injuries. Proper form is essential to maximize benefits and minimize strain on the knees and lower back during the exercise.
