If your goal is to build bigger hamstrings, use the seated leg curl machine instead of the lying (prone) one.
Key Takeaways
- More Muscle Growth: Seated leg curls build more muscle size than lying leg curls. This is because sitting down puts the main hamstring muscles into a deeper stretch while you work them.
- Equal Muscle Damage: Muscle damage is normal during lifting exercises; more damage = more time needed to recover. Whether itâs seated or prone leg curls, seated produces more muscle growth, but the damage is about the same as prone, so recovery time is about the same.
Coach Julioâs Recommendation đ€: Stick to the seated leg curl if you want to grow hamstring size.
