Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.
The Self Assisted Inverse Leg Curl (on Floor) is a targeted isolation upper legs movement designed to train the Hamstrings with direct engagement of the Calves.
Open-chain single-joint knee flexion isolating the biceps femoris, semitendinosus, and semimembranosus with minimal spinal fatigue. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
Doing this hamstring curl on the floor rather than a padded platform changes the friction and support under the knees, which usually makes it feel harder to control the descent. It's still fundamentally the same eccentric-loading pattern — kneeling, falling forward, catching yourself with the arms as the hamstrings resist. Anchor the ankles securely; without that, the movement doesn't work at all.
How to Do the Self Assisted Inverse Leg Curl (on Floor)
- Lie face-up on the floor with your legs straight and your arms resting at your sides.
- Bend your knees and plant your feet flat on the floor, hip-width apart.
- Raise your hips off the floor by engaging your glutes and hamstrings.
- Slowly drag your feet toward your glutes while keeping your hips raised.
- Pause briefly at the top, then slowly straighten your legs back out.
- Bring your hips back down to the floor.
- Continue for the set reps, taking care to lower with control and reset your posture between each rep.
Recommended Sets & Reps by Training Goal
65–75% 1RM · 60s rest
50–60% 1RM · 30–45s rest
Controlled 3s eccentric · 60s rest
Biomechanical & Joint Load Cues
Open-chain single-joint knee flexion isolating the biceps femoris, semitendinosus, and semimembranosus with minimal spinal fatigue.
Common Mechanical Mistakes & Form Errors to Avoid
- Lifting Hips Off the Pad: Allowing hips to rise into anterior pelvic tilt during lying curls shifts tension off the hamstrings onto the lower back.
- Pointed Toes (Plantarflexion): Pointing toes excessively recruits the gastrocnemius (calf) to assist the curl rather than isolating the hamstrings.
- Shortchanging the Bottom Stretch: Reversing the movement before reaching full knee extension misses the high-hypertrophy lengthened position.
Proper Breathing Patterns & Core Engagement
Inhale as legs extend to full stretch; exhale as heels curl tightly toward glutes.

Injury Modification & Joint Safety
Ensure knee joint axis aligns precisely with the machine pivot point to prevent shear stress on cruciate ligaments. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Upper Legs exercises category.
Muscles Worked
The Self Assisted Inverse Leg Curl (on Floor) primarily targets the Hamstrings, with Glutes as the primary synergist muscle group, along with the Calves.

FAQ
- What muscles does the Self Assisted Inverse Leg Curl (on Floor) work?
- The Self Assisted Inverse Leg Curl (on Floor) primarily targets the hamstrings as the primary agonist. Synergist assistance is provided by the glutes along with the calves. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Self Assisted Inverse Leg Curl (on Floor)?
- The Self Assisted Inverse Leg Curl (on Floor) is performed using no equipment — just body weight. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Self Assisted Inverse Leg Curl (on Floor)?
- The most frequent error is lifting hips off the pad: Allowing hips to rise into anterior pelvic tilt during lying curls shifts tension off the hamstrings onto the lower back.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Self Assisted Inverse Leg Curl (on Floor)?
- For muscle growth and density, execute 3 to 4 working sets of 10 to 15 controlled repetitions with 60 seconds rest, emphasizing a deep stretch and deliberate peak contraction on every rep.
- What's a good alternative to the Self Assisted Inverse Leg Curl (on Floor)?
- If you don't have access to the space or setup it needs, the Barbell Good Morning targets the same hamstrings using barbell instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
