Slider Leg Curl
How to Do a Slider Leg Curl
Lie on your back with a slider under each heel and the knees slightly bent.
Place the arms on the floor for balance, brace the core, and keep the spine neutral.
Press through the heels and raise the hips so the body forms a controlled line from shoulders toward knees.
Slowly slide the heels away from the body, extending the knees while resisting the movement with the hamstrings.
Go only as far as you can control without the lower back arching or the hips dropping uncontrollably.
Pull the heels back toward the glutes by flexing the knees and squeezing the hamstrings while raising or maintaining the hips.
Pause briefly near the top, then repeat with the same slow, controlled slider path.
Form Check & Technique
DO THIS (Technique Tips)
- Use a smooth, predictable surface.
- Keep pressure through the heels.
- Brace the core before sliding.
- Control the outward eccentric.
- Keep hip motion deliberate rather than uncontrolled.
- Use eccentric-only reps as a regression.
- Progress to single-leg curls gradually.
AVOID THIS (Common Mistakes)
- Letting the Hips Collapse — Fix: maintain glute tension and only use the range you can control.
- Overarching the Lower Back — Fix: brace the core and keep the spine neutral as the hips rise.
- Pushing Through the Toes — Fix: keep pressure through the heels as recommended by Muscle & Fitness.
- Sliding Too Fast — Fix: slow both the outward and inward phases to keep the hamstrings working.
- Using a Surface With Unpredictable Friction — Fix: test sliders or towels before the set and clear the floor.
- Jumping to Single-Leg Reps Too Soon — Fix: master bilateral or eccentric-only work first.
About Slider Leg Curl
The slider leg curl is a floor-based hamstring exercise performed with sliding discs, furniture sliders, or towels on a smooth surface. From a supine position, you slide the heels away and back while controlling the hips, which trains the hamstrings through knee flexion and eccentric knee extension while the glutes and core stabilize the pelvis.
Slider Leg Curl Muscles Worked
The hamstrings flex the knees to pull the heels back and work eccentrically as the legs slide away.
- The glutes help maintain hip extension, while the core stabilizes the pelvis and spine.
- The calves can assist depending on ankle position and how force is applied through the heels.
Sets & Reps Guidance
Technique / Learning
Technique: 2–4 sets of 5–8 eccentric-only or short-range repetitions.
Strength Focus
Strength: 3–4 sets of 6–10 controlled reps, or lower-rep single-leg variations once bilateral work is easy.
Muscle Growth (Hypertrophy)
Muscle growth: 3–4 sets of 8–15 slow repetitions with consistent hamstring tension.
General training baseline. Need.fit automatically adjusts exact sets, reps, and working weight based on your individual fitness level, recovery, and progress over time.

Lying Leg Curl
Machine knee-flexion exercise with easy external-load progression.
Glute-Ham Raise
GHD-based hamstring exercise combining knee flexion and hip mechanics.
Barbell Back Squat

Romanian Deadlift
Learn Romanian deadlift form, muscles worked, hip-hinge and bar-path cues, proper depth, common mistakes, RDL vs deadlift differences, and sets and reps.
Slider Leg Curl vs Swiss Ball Leg Curl
Both combine hamstring knee flexion with hip and trunk control.
- Sliders move along the floor and create resistance through friction, while a Swiss ball adds a larger instability challenge.
- The best choice depends on your floor surface, equipment, and ability to keep the hips controlled.
Slider Leg Curl as a Nordic Curl Regression
Fitness Drum describes sliding curls as a beginner-friendly alternative to Nordic curls. Sliders let you control the lever and range more easily, making them useful before progressing to the much larger bodyweight demand of a Nordic.
Eccentric-Only Slider Curl
If pulling the heels back is too difficult, bridge up with the knees bent and slowly slide the legs outward for several seconds.
- Lower the hips, reset the feet, and repeat.
- This lets you train the eccentric phase before you can complete full repetitions.
Should Your Hips Stay High?
Muscle & Fitness recommends keeping the hips up and the spine neutral.
- Some sliding-curl styles allow the hips to lower somewhat as the legs extend and then rise again as the heels return.
- Whichever style you use, avoid uncontrolled sagging or lumbar hyperextension.
Can You Use Towels Instead of Sliders?
Yes.
- Towels can work well on smooth hardwood or tile, while plastic furniture sliders or similar discs can work on carpet.
- The surface changes the friction, so test the movement with a small range before doing a full set.
Single-Leg Slider Curl Progression
Once bilateral repetitions are controlled, perform the curl with one heel on a slider and the other leg lifted. The unilateral version significantly increases hamstring and pelvic-stability demands, so reduce the range or use eccentric-only reps at first.
How to Program Slider Leg Curls
Use them as a home hamstring exercise, an accessory after hip hinges, or a bridge between machine curls and harder bodyweight exercises. Slow repetitions generally provide a better training stimulus than rushing for high rep counts.
