Seated vs. Lying Leg Curl Benches: What’s the Difference?

Blog Article

If you’ve ever walked into a gym and noticed both a seated leg curl machine and a lying leg curl bench, you might have wondered: “Aren’t they doing the same thing?” While both machines train your hamstrings, the difference in body position changes how and where the muscles are activated — which can impact your results.

In this article, we’ll break down the differences between seated and lying leg curl benches, so you can choose the best option for your goals, training level, and body type.

 First, What Do Leg Curl Benches Target?

Both types of leg curl machines focus primarily on the hamstrings — the muscles along the back of your thigh. These muscles are responsible for knee flexion and hip extension, making them crucial for:

• 
  

  Sprinting and running

  
  


• 
  

  Jumping and explosive movements

  
  


• 
  

  Injury prevention (especially ACL tears)

  
  


• 
  

  Squat and deadlift strength

  
  

Leg curls isolate the hamstrings by flexing the knee without significant involvement from the hips — and the position you’re in affects how well that happens.

 Seated Leg Curl Bench: The Breakdown

 Body Position:

You sit upright with your legs extended in front of you, then curl your legs downward against resistance.

 Benefits:

• 
  

  Greater hamstring stretch at the start of the movement, which can lead to more effective muscle activation.

  
  


• 
  

  Keeps the hips fixed in a flexed position, emphasizing the lower portion of the hamstring (closer to the knee).

  
  


• 
  

  Often better for taller lifters or those with tight hips, as it's more comfortable.

  
  

 Drawbacks:

• 
  

  Slightly more stress on the lower back if posture isn’t maintained.

  
  


• 
  

  May feel awkward for beginners at first due to the seated setup.

  
  

Best for:

• 
  

  Muscle growth and hypertrophy

  
  


• 
  

  Improving knee flexion strength

  
  


• 
  

  Lifters who prefer controlled, seated positions

 Lying Leg Curl Bench: The Breakdown

 Body Position:

You lie face down on a bench with your legs extended, then curl your feet toward your glutes.

 Benefits:

• 
  

  A classic hamstring isolation exercise, great for targeting the middle of the hamstring.

  
  


• 
  

  Involves some hip extension stability, adding a slight glute and core challenge.

  
  


• 
  

  May feel more intuitive for beginners.

  
  

 Drawbacks:

• 
  

  Less hamstring stretch at the start compared to the seated version.

  
  


• 
  

  Not ideal for people with lower back issues or tight hips.

  
  

Best for:

• 
  

  General strength training

  
  


• 
  

  Athletes looking for functional hamstring work

  
  


• 
  

  Lifters with good mobility and back control

 Which One Should You Use?

Use the seated leg curl bench if you:

• 
  

  Want to maximize muscle growth through greater stretch

  
  


• 
  

  Have tight hips or back issues

  
  


• 
  

  Need better isolation of the lower hamstrings

  
  

Use the lying leg curl bench if you:

• 
  

  Are an athlete or runner looking for balanced strength

  
  


• 
  

  Prefer a compact setup

  
  


• 
  

  Want to strengthen core and hip stability at the same time

  
  

???? Best strategy: If your gym has both machines, alternate between them every few workouts. This ensures you train the hamstrings through different angles and stretch patterns for complete development.

 Final Thoughts

Both seated and lying leg curl benches are excellent tools for building strong, injury-resistant hamstrings. The main difference lies in your position — seated gives you more stretch and isolation, while lying offers a classic hamstring challenge with a different range of motion.
