Lying Straight Leg Marches
Lying Straight Leg Marches Exercise Description
Lying Straight Leg Marches are a supine core stability drill that trains you to keep the trunk and pelvis steady while the hips move. The movement emphasizes anti-extension control of the lumbopelvic region, with the abdominal wall (rectus abdominis, transverse abdominis, and the internal/external obliques) working isometrically to maintain a neutral spine. The hips move through alternating straight‑leg flexion, primarily using the iliopsoas and rectus femoris, while the quadriceps help keep the knees extended. Because the torso stays quiet, this exercise highlights coordination between breathing, bracing, and hip motion without external load. It’s a clear, beginner‑friendly way to feel what “ribs stacked over pelvis” means and to practice precise range of motion that does not disturb the low back position.

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 neutral spine: ribs stacked over pelvis; lightly brace your abdominal wall.
– Keep your head relaxed and shoulders wide; breathe steadily throughout.
– Press both knees long (full but comfortable extension); ankles neutral.
– Without letting your low back arch or ribs flare, raise one straight leg by flexing the hip.
– Lift only to the height where your pelvis stays level and still.
– Pause briefly with control, then lower the leg to a light floor touch (no thud).
– Alternate legs in a smooth, continuous march while maintaining the same trunk position.
– Keep both thighs pointing straight up; avoid external rotation or toe‑out.
– If your low back begins to lift or your pelvis tilts, reduce the lift height and re‑brace before continuing.
Lying Straight Leg Marches Tips
‘- Before you start, set a neutral spine by stacking your ribs over your pelvis and lightly bracing your abdominal wall.
– Keep your head relaxed and shoulders wide on the floor so the trunk can stay quiet.
– Press both knees long into full but comfortable extension and keep your ankles neutral to maintain straight legs.
– Breathe steadily throughout the set instead of holding your breath.
– As you lift a leg, do not let your low back arch or your ribs flare.
– Lift each leg only to the height where your pelvis stays level and still.
– Pause briefly with control at the top, then lower the leg to a light floor touch instead of letting it thud.
– Alternate legs in a smooth, continuous march while keeping the same trunk position the whole time.
– Keep both thighs pointing straight up and avoid letting the leg externally rotate or the toes turn out.
– If your low back starts to lift or your pelvis tilts, reduce the lift height and re-brace before continuing.
Lying Straight Leg Marches Beginner Introduction
Lying Straight Leg Marches introduce a controlled marching action performed while lying on the back. The legs stay long and move one at a time from the hips, while the rest of the body stays quiet against the floor. This creates a stability challenge for the midsection, asking the abs and surrounding core muscles to hold the natural curve of the spine steady instead of letting the low back tip or arch with each leg lift.
Because the hips travel through a straight-leg lifting pattern, the front of the hips and the front of the thighs take on most of the movement work, while the core holds a steady brace. Breathing rhythm, tension through the midsection, and smooth leg motion all interact, so the drill highlights how breath and bracing can support hip motion without help from weights or bands. Many beginners find it useful for learning what an aligned relationship between ribcage, spine, and pelvis feels like, along with a clear sense of how high each leg can lift before the low back position starts to change.
