The suspension leg curl is a bodyweight hamstring exercise performed lying on your back with your heels loaded into the foot cradles of a suspension trainer. It targets the hamstrings through a full curl motion while the gastrocnemius assists, and the bridged hip position adds a demanding core and glute stability component throughout the set.
Cómo hacer el Suspension Leg Curl
- 1Set the suspension trainer so the foot cradles hang about 6–12 inches off the floor. Lie on your back beneath the anchor point and place both heels inside the foot cradles.
- 2Extend your legs fully so your body forms a straight line from shoulders to heels, with your arms flat on the floor beside you for support.
- 3Press your heels down into the cradles and drive your hips up until your body is in a straight bridge position — shoulders, hips, and heels aligned.
- 4Keeping your hips raised throughout, curl your heels toward your glutes by bending at the knees.
- 5Continue curling until your knees are fully bent and your heels are close to your hips.
- 6Slowly extend your legs back to the starting straight position, resisting gravity the entire way.
- 7Complete all reps without letting your hips sag back to the floor between repetitions.
Consejos de técnica
- Keep your hips fully extended and level during the curl — letting them drop shifts load away from the hamstrings and strains the lower back.
- Move slowly on the way down; the eccentric phase is where most of the hamstring development happens.
- If the full movement is too difficult, shorten the range of motion or lower the cradle height slightly, and build up to full-depth curls as your hamstrings get stronger.
- Keep your arms flat on the floor and avoid pushing into the ground — use them only for light balance, not to offload the work.
Errores comunes
- Letting the hips sag during the curl, which removes tension from the hamstrings and places stress on the lumbar spine.
- Rushing the return phase by letting gravity snap the legs straight, which wastes the eccentric loading and increases injury risk.
- Using the arms to push off the floor, which artificially unloads the hamstrings and reduces the training stimulus.
- Setting the cradles too high, causing an unstable angle that makes it nearly impossible to maintain a neutral hip bridge.
Preguntas frecuentes
What muscles does the suspension leg curl work?
The suspension leg curl primarily targets the hamstrings. The gastrocnemius (calf) acts as a synergist, and the glutes and core muscles work isometrically to keep the hips bridged throughout the movement.
How is the suspension leg curl different from a lying leg curl machine?
Unlike a machine, the suspension version requires you to stabilize your hips and core throughout every rep, making it a more demanding full-body movement. It also allows a greater range of functional hamstring loading with no equipment other than a suspension trainer.
How do I make the suspension leg curl easier or harder?
To make it easier, keep your arms pressed lightly into the floor or lower the cradle height slightly. To increase difficulty, cross your arms over your chest, elevate your shoulders on a bench, or perform single-leg curls.
How many reps should I do?
For most people, 3–4 sets of 8–12 controlled reps is an effective starting range. Because the exercise is highly dependent on stability, prioritize quality over rep count and stop a set if your hips begin to drop.
