Lying Leg Extension
Lying Leg Extension Exercise Description
Lying Leg Extension is a supine, bodyweight core exercise that trains lumbopelvic control while the legs move. The abdominal wall (rectus abdominis and obliques) works isometrically to resist lumbar extension as the hip flexors (primarily iliopsoas and rectus femoris) extend the legs away from the torso. The goal is maintaining a quiet pelvis and neutral spine—no arching—through a controlled range that you can stabilize. This “long‑lever” position increases the demand on the anterior core, making precise bracing and breathing essential. Use a smooth tempo and stop the descent of your legs the moment your low back wants to lift from the floor.

How To Do The Lying Leg Extension Exercise
‘- Lie on your back with head and spine neutral; arms by your sides, palms down for light support.
– Bring hips and knees to 90/90 (tabletop), shins parallel to the floor.
– Brace gently as if preparing for a cough; keep lower ribs down and pelvis steady.
– Inhale to prepare; exhale as you slowly extend both knees and lower the legs on a shallow diagonal.
– Stop before your low back lifts or your pelvis tilts—range is dictated by your ability to maintain control.
– Pause briefly while staying braced; keep shoulders relaxed and neck neutral.
– Inhale as you return the legs to tabletop with the same control.
– Keep knees softly extended (not locked) and movement smooth—no swinging or momentum.
– If control is lost, reduce the lowering range or extend one leg at a time while the other remains in tabletop.
– Finish by bending knees and setting feet down under control.
Lying Leg Extension Tips
‘- Start lying on your back with your head and spine neutral, arms by your sides and palms down for light support.
– Set your hips and knees to a 90/90 tabletop position with shins parallel to the floor before you begin moving.
– Gently brace “as if preparing for a cough” to keep your lower ribs down and your pelvis steady.
– Exhale as you slowly extend both knees and lower your legs on a shallow diagonal.
– Stop lowering the legs the moment your low back wants to lift or your pelvis starts to tilt.
– Keep your pelvis quiet and your spine neutral—no arching—as the legs move.
– Pause briefly in the extended position while staying braced, with shoulders relaxed and neck neutral.
– Inhale as you return your legs to tabletop with the same smooth, controlled tempo.
– Keep your knees softly extended (not locked) and avoid swinging or using momentum.
– If you lose control, reduce how far you lower your legs or switch to extending one leg at a time while the other stays in tabletop.
Lying Leg Extension Beginner Introduction
Lying Leg Extension is a floor-based core movement performed on the back, using only bodyweight. The legs act as a long lever, reaching away from the torso while the midsection stays steady. The abs and side abs stay engaged without shortening or crunching, while the hip flexors and the front of the thighs guide the legs through a small, deliberate arc. Throughout the motion, the aim is a calm, stable pelvis and a spine that does not lift or arch, so the work stays centered in the core rather than shifting into the lower back.
This exercise highlights slow, precise control instead of speed or big ranges of motion. Breathing patterns are coordinated with the leg motion, promoting strong bracing without unnecessary tension in the neck or shoulders. The movement can be tailored by adjusting how far the legs travel, with many people limiting the drop to the point where the low back can still stay connected to the floor. A variation with one leg extending while the other remains bent is sometimes used when a lighter challenge or extra stability is desired.
