The sliding leg curl on floor with towel is a bodyweight exercise that targets the gluteus maximus and hamstrings through an active hip-extension and knee-flexion pattern, with the gastrocnemius and soleus contributing as synergists. Placing your feet on a folded towel on a smooth floor creates the sliding resistance that challenges your posterior chain through a full range of motion. It suits lifters who want to train the hamstrings and glutes with no equipment beyond a towel.
How to do the Sliding Leg Curl on Floor with Towel
- 1Lay a folded towel on a smooth, low-friction floor surface. Lie flat on your back with your arms at your sides, palms pressing into the floor for stability.
- 2Place both heels on the center of the towel with your legs extended and your feet hip-width apart. Keep your toes pulled up toward your shins.
- 3Brace your core, squeeze your glutes, and drive your hips off the floor until your body forms a straight line from shoulders to heels.
- 4Keeping your hips elevated and glutes engaged, dig your heels into the towel and slide your feet toward your hips by flexing your knees. Your hips should rise slightly higher as your knees bend.
- 5Continue curling until your knees are bent to roughly 90 degrees and your feet are directly under or just past your knees.
- 6Pause for one count at the top, maintaining full glute contraction and a neutral spine.
- 7Slowly slide your heels back out along the floor, extending your legs under control until they are nearly straight. Do not let your hips drop during the return.
- 8Complete all reps, then lower your hips to the floor in a controlled manner to finish the set.
Form tips
- Press your arms and palms firmly into the floor throughout the movement — this helps stabilize your torso and prevents your hips from rotating.
- Lead the curl with your heels, not your toes. Actively digging your heels into the towel increases hamstring activation on both the pull and the slide-out phases.
- Control the eccentric (slide-out) phase by counting two to three seconds — this is where the hamstrings do the most work and where most of the strength adaptation occurs.
- Keep your knees tracking directly over your second toe during the curl; letting them cave inward reduces hamstring tension and stresses the knees.
- If your hips sag mid-set, reglue your glutes before each rep rather than grinding through with poor position — the exercise loses its effect as soon as your hips drop.
Common mistakes
- Letting the hips drop during the slide-out phase, which removes tension from the hamstrings and shifts load to the lower back.
- Rushing the eccentric by snapping the feet back out instead of controlling the slide, cutting the time under tension in half and reducing strength gains.
- Pushing through the toes rather than digging through the heels, which shifts the workload from the hamstrings to the calves and reduces glute engagement.
- Hyperextending the lower back at the top position to fake more hip height, which compresses the lumbar spine instead of loading the glutes and hamstrings.
- Starting with hips too low at setup so the body is never in a full bridge position, which limits the range of motion and reduces the challenge on the posterior chain.
Frequently asked questions
What muscles does the sliding leg curl on floor with towel work?
The primary muscles are the gluteus maximus and hamstrings. The gastrocnemius and soleus contribute as synergists by helping flex the knee and stabilize the ankle throughout the movement.
What type of floor works best for the sliding leg curl?
A smooth hardwood, laminate, or tile floor provides the least friction and gives the towel a consistent slide. Carpet creates too much drag and makes it difficult to control the movement.
How is the sliding leg curl different from a regular glute bridge?
A glute bridge holds a static hip-extended position and primarily loads the glutes. The sliding leg curl adds a knee-flexion phase, which recruits the hamstrings through a longer range of motion and increases the eccentric demand on both the hamstrings and glutes.
Can beginners do this exercise?
Yes, but the eccentric slide-out is challenging for beginners. Start with a shorter range of motion — curling only partway — and focus on keeping the hips up. Build to a full range over several sessions before adding reps.
How many reps and sets should I do?
Two to four sets of eight to twelve reps is a practical starting range for strength and hypertrophy. Because there is no external load, prioritizing slow eccentrics and pausing at the top of each rep increases the difficulty without needing more reps.
