The human body is a complex masterpiece of muscles and joints, each playing a crucial role in everyday movement. Among these vital components, the hamstrings stand out as a group of three muscles located on the back of the thighs, often overlooked and underappreciated. Yet, these mighty muscles are indispensable in numerous day-to-day activities, from walking and climbing stairs to bending over and lifting objects. 

Since your hamstrings are involved in so much, hamstring weakness can affect a lot of different daily activities and make you more prone to injury or knee pain. The good news: There’s plenty you can do to strengthen your hamstrings, such as hamstring curls (sometimes called leg curls). Keep reading to learn more about how hamstring curls can benefit you, and how you can incorporate them into your routine.

What Is a Hamstring Curl?

A hamstring curl is a strengthening exercise that involves bending your knee from a standing position so your heel moves toward your butt as it lifts your lower leg. Hamstring curls can be done on exercise machines, but they’re also easy to do on your own at home, without any equipment.

What Muscles Does the Hamstring Curl Work?

You guessed it. Hamstring curls are an isolation exercise that primarily work your hamstrings, which activate as you lift your heel up to your butt. This helps with knee flexion (bending) in everyday life, as well as hip extension (opening your hips up). Along with building leg strength, hamstring curls can improve balance and stability. 

Hamstring Curl Benefits

By building strength in your hamstrings, this simple-but-powerful exercise can benefit you in several ways, including: 

• Improving balance and mobility 

• Improving leg stability, which can reduce the risk of injuries, especially in the knees and lower back 

• Improving overall knee health by balancing strength in the quadriceps (front thigh muscles) and hamstrings

• Supporting your lower back and alleviating back discomfort in daily activities

• Making it easier to walk, run, climb stairs, and stand up from a seated position
