Lying Straight Leg Marches
Lying Straight Leg Marches Exercise Description
Lying Straight Leg Marches are a supine, bodyweight variation of alternating straight‑leg raises that trains hip flexion while your trunk stays stable. The primary movers are the hip flexors (iliopsoas and rectus femoris), with the quadriceps maintaining knee extension; the anterior core (rectus abdominis, obliques, and transverse abdominis) resists pelvic tilt and lumbar extension. The goal is controlled hip flexion without your lower back arching or your pelvis rocking, reinforcing lumbo‑pelvic stability. This makes it a useful drill for learning to brace the trunk while one leg moves, a fundamental pattern for many athletic and daily tasks. Use a comfortable range of motion—stop the lift when your pelvis wants to move or your hamstrings limit further motion.

How To Do The Lying Straight Leg Marches Exercise
‘- Lie on your back with legs straight, feet hip‑width, arms by your sides, palms down.
– Set a light abdominal brace: ribs down, pelvis neutral, and lower back maintaining its natural curve (avoid arching).
– Dorsiflex both ankles. Keep knees extended but not locked.
– Without shifting your pelvis, slowly raise the right leg until you feel hamstring tension or notice your spine/pelvis wanting to move—pause briefly.
– Lower the leg under control to the start position; keep both legs quiet (no bouncing or swinging).
– Repeat with the left leg, alternating sides with the same controlled tempo.
– Breathe: exhale through the lift; inhale as you lower.
– Keep your head and shoulders relaxed; avoid jutting the chin or flaring the ribs.
– Quality checks: pelvis stays level, lower back does not arch, toes point up, and both knees remain straight.
– Modify as needed: bend the non‑moving knee with the foot planted to increase trunk stability, or reduce the lift height; use a slight knee bend on the lifting leg if hamstring flexibility limits range.
Lying Straight Leg Marches Tips
‘- Set a light abdominal brace with ribs down and pelvis neutral before you start moving.
– Maintain your lower back’s natural curve and avoid letting it arch as the leg lifts.
– Dorsiflex both ankles so your toes point up throughout the movement.
– Keep your knees extended but not locked while you march.
– Lift the leg only until you feel hamstring tension or your pelvis/spine wants to move, then stop.
– Move the lifting leg slowly and lower it under control, avoiding any bouncing or swinging.
– Exhale as you lift the leg; inhale as you lower it back down.
– Keep your head and shoulders relaxed, avoiding chin jutting or rib flaring.
– Watch that your pelvis stays level and quiet, with both knees remaining straight.
– If your trunk is unstable, bend the non‑moving knee with the foot planted or reduce the lift height; if hamstrings are tight, use a slight knee bend on the lifting leg.
Lying Straight Leg Marches Beginner Introduction
Lying Straight Leg Marches are a bodyweight floor exercise performed while lying on your back, with one leg lifting at a time in a straight position. The movement centers on bending at the hip while the rest of the body stays as still as possible, so the work shifts toward the hip flexors and front thighs. The abs and side abs support the front of the torso, helping the lower back and hips stay steady as each leg rises and lowers in turn.
This drill emphasizes control more than height or speed. The intention is smooth, deliberate leg motion while the pelvis and lower spine remain quiet, building a strong link between the hips and core that carries over to walking, running, and many athletic movements that involve one leg at a time. A calm breathing pattern and relaxed upper body encourage better trunk bracing. Range of motion often depends on hamstring flexibility and how well the pelvis stays stable, so the lift height naturally adjusts to the person performing it.
