Dumbbell Lying Leg Curl
Dumbbell Lying Leg Curl Exercise Description
The dumbbell lying leg curl trains knee flexion with free weights while you lie prone on a flat bench. Primary movers are the hamstrings (biceps femoris, semitendinosus, semimembranosus). The gastrocnemius can assist, and the glutes, deep abdominals, and spinal extensors stabilize the pelvis and lumbar spine. Because the hamstrings cross the knee (and two heads cross the hip), keeping the hips quiet and the spine neutral helps direct the work to the target muscles. Plantarflexing the ankles (toes pointed) shortens the gastrocnemius, which can reduce calf contribution and emphasize hamstrings. The movement should occur at the knees with the thighs supported, avoiding hip lift, lumbar extension, or knee flare. Control matters—use a smooth curl up and a deliberate return to full extension without locking out or dropping the weight.

How To Do The Dumbbell Lying Leg Curl Exercise
‘- Place a dumbbell upright at the end of a flat bench.
– Lie prone with your thighs on the bench and knees just beyond the edge so they can bend freely.
– Grip the bench, brace your midline, and set a neutral head, neck, and spine.
– Secure the dumbbell between your feet/arches; press the inner edges of your feet together to hold it.
– Keep legs straight but not hyperextended; ankles neutral or slightly plantarflexed.
– Curl the dumbbell by flexing your knees, keeping thighs pressed to the bench and pelvis still.
– Stop before your hips lift or your low back arches; pause with heels moving toward the glutes.
– Lower under control to near full knee extension without resting the dumbbell on the floor.
– Keep knees hip-width and tracking straight; avoid outward flare or inward collapse.
– To finish, lower the dumbbell to the floor gently before releasing your feet (or have a spotter assist).
Dumbbell Lying Leg Curl Tips
‘- Lie with your thighs fully supported on the bench and your knees just beyond the edge so they can bend freely.
– Brace your midline and keep your head, neck, and spine neutral to stabilize the pelvis and lumbar spine.
– Squeeze the inner edges of your feet together to secure the dumbbell between your feet/arches.
– Keep your legs straight but not hyperextended before you start curling the weight.
– Slightly plantarflex (point) your ankles if you want to reduce calf involvement and emphasize the hamstrings.
– Curl the dumbbell by flexing only at the knees, keeping your thighs pressed into the bench and your pelvis still.
– Stop the curl before your hips lift or your low back arches, with your heels moving toward your glutes.
– Lower the dumbbell under control to near full knee extension without resting it on the floor or locking out.
– Maintain hip-width spacing with your knees and track them straight, avoiding outward flare or inward collapse.
– At the end, gently lower the dumbbell to the floor before releasing your feet (or have a spotter assist).
Dumbbell Lying Leg Curl Beginner Introduction
The dumbbell lying leg curl is a free-weight exercise performed face-down on a flat bench, with the weight held between the feet. The movement centers on bending the knees against resistance while the upper legs rest on the bench, turning this into a targeted drill for the hamstrings along the back of the thighs. The calves can share some of the work, while the glutes, abs, and lower back contribute by steadying the hips and trunk so the motion stays concentrated at the knees.
A key theme in this curl is controlled, deliberate movement rather than swinging the weight. The bench supports the thighs while the knees travel through a comfortable bending and straightening path, and the pelvis and lower spine remain stable rather than lifting or arching. Pointed ankles change how much the calves participate, shifting more effort into the hamstrings. Consistent spacing of the knees and smooth transitions between the bent and straight positions highlight alignment, body awareness, and tension through the full range of motion.
