What Are Leg Curl Exercises?

Leg curls are an isolation exercise that specifically targets the hamstring muscles. These muscles are crucial for various daily activities like walking, running, jumping, and climbing stairs. Strengthening your hamstrings can help improve your athletic performance and protect you from injuries.

Muscles Involved in a Leg Curl Exercise

A leg curl is sometimes called a hamstring curl because it works the hamstring muscle. Even though the term “hamstring” actually refers to a collection of muscles in the rear of the upper leg:

  • The biceps femoris, or outside hamstring, facilitates external rotation of the lower leg, hip extension, and knee flexion.
  • The semitendinosus, also known as the inner hamstring, facilitates hip extension, medial rotation of the lower leg, and knee flexion.
  • The semimembranosus, which is positioned in between the other two hamstring muscles, facilitates internal rotation of the lower leg during knee flexion as well as hip extension.

The leg curl exercise activates the muscles in the thigh and shin areas in addition to the glute and calf muscles. Thus, leg curls are an effective technique to strengthen your entire lower body.

Performing Leg Curls Exercises with Proper Form

  1. To correctly position yourself for leg curls, ensure your torso is flat against the bench and your legs are extended under the lever pad. The lever pad should be situated just above your heels.
  2. For stability during the exercise, it’s important to grab onto the machine handles.
  3. When you’re ready to begin the leg curl exercises, slowly curl up your legs as far as possible, taking care not to lift your thighs off the bench. Be sure to squeeze your hamstrings at the peak of the movement.
  4. Finally, return the weight to its starting position by slowly lowering your legs. Be sure to fully extend your legs during this phase of the exercise.

Why Vary Leg Curl Exercises?

You might be asking yourself why you would want to switch up your hamstring curl if it has all these advantages. The fact that each version will target the muscle differently is one explanation.

It works the same muscle in the biceps as a bicep curl or hammer curl. The short head of the bicep is more effectively activated by the bicep curl, though. The long head of the bicep is more effectively activated by the hammer curl.

It’s also possible that you don’t have access to a particular leg curl machine, therefore switch up this exercise. Not every gym has every kind of curling equipment made. Some just have equipment for seated leg curls. Some simply have tools for the laying leg curl. There are also gyms without any curling machines at all.

You can work your legs hard in all of these scenarios if you know the various variables. For example, you are aware of how to swap out a curling machine for a barbell. You can also perform the leg curl without using any weight at all.

Stability Ball Hamstring Curl: This is a great home variation. Lay on your back with your feet on a stability ball. Lift your hips and roll the ball towards you by curling your legs.

Resistance Band Leg Curl: This can be done at home or in the gym. Secure a resistance band around a stable post, lie down on your stomach, and loop the band around your ankles. Curl your legs towards your buttocks.

Common Mistakes While Doing Leg Curl Exercises

  1. Using Too Much Weight: This can result in poor form and potential injury. Start with a manageable weight and gradually increase as your strength improves.
  2. Rushing Through the Exercise: Slow, controlled movements are key to maximising muscle engagement and preventing injury.
  3. Not Fully Extending the Legs: Make sure to fully extend your legs in the downward phase of the exercise for a full range of motion.
  4. Lifting Your Torso Off the Bench: Keep your torso flat against the bench throughout the exercise.

Leg Curl Exercises Benefits

Leg Curl Exercises Benefits
  1. Hamstring Strength: The primary benefit of leg curls is that they target your hamstring muscles located at the back of your thighs. With consistent training, your hamstrings will grow stronger, enhancing your ability to perform movements that require lower body strength, such as running, jumping, or even simple tasks like climbing stairs.
  2. Improved Muscle Balance: Our bodies work best when our muscles are evenly balanced. However, it’s common for the quadriceps (muscles on the front of the thigh) to be stronger than the hamstrings. This imbalance can lead to strain and potential injury. Leg curls help to strengthen the hamstrings and restore balance between these opposing muscle groups, reducing the risk of injury.
  3. Better Posture: Strong hamstrings play a crucial role in maintaining good posture. They support the pelvis and enable proper spinal alignment. By strengthening your hamstrings with leg curls, you can improve your overall posture, which can alleviate common issues such as lower back pain.
  4. Increased Flexibility: Performing leg curls regularly can enhance your flexibility, particularly in the knee joint and hamstring muscles. This increased range of motion can improve your performance in other exercises and physical activities and reduce the risk of strains or tears.
  5. Aesthetic Appeal: If aesthetic improvement is one of your fitness goals, leg curls can help you achieve more toned and defined legs. As an isolation exercise, leg curls target the hamstring muscles effectively, contributing to a more sculpted appearance over time.
  6. Injury Prevention: Hamstring injuries are common, especially among athletes who participate in sports that involve sprinting or sudden stops and starts. By strengthening the hamstrings, leg curls can provide a protective effect and decrease the likelihood of such injuries.
