Lying Simultaneous Alternating Straight Leg Raise
Lying Simultaneous Alternating Straight Leg Raise Exercise Description
The Lying Simultaneous Alternating Straight Leg Raise trains hip flexion while your trunk resists movement. You lift one straight leg at a time from a supine position, challenging the anterior core to keep the pelvis level and the lumbar spine from arching. Primary movers are the hip flexors (iliopsoas and rectus femoris); the rectus abdominis, transverse abdominis, and obliques brace isometrically for lumbopelvic control. Alternating legs increases the anti-extension demand and limits momentum, promoting precise motor control through a comfortable range. Limit the height of each raise to what you can perform without rib flare or pelvic tilt. Keep the movement slow and smooth to emphasize control. Maintain a neutral head and neck, and use your arms by your sides for stability. Exhale during the lift to support bracing and keep steady breathing throughout.

How To Do The Lying Simultaneous Alternating Straight Leg Raise Exercise
‘- Lie supine, legs long and hip-width, arms by sides, palms down.
– Set position: draw ribs down, lightly brace, and keep a gentle posterior pelvic tilt.
– Keep head and neck neutral; gaze straight up.
– Option: keep the nonworking heel on the floor, or hover it slightly.
– Inhale to prepare; exhale as you lift one straight leg by flexing the hip.
– Stop before the pelvis tips or the low back lifts from the floor.
– Knee stays straight but not locked; reach long through the heel.
– Pause briefly with control at the top.
– Lower the leg slowly to the start without changing trunk position.
– Switch legs smoothly and continue alternating with calm, even breaths.
– If hamstrings limit motion or the pelvis moves, reduce height or allow a slight knee bend.
– Avoid arching the lower back, flaring ribs, lifting the head, or rocking the hips.
Lying Simultaneous Alternating Straight Leg Raise Tips
‘- Before lifting, draw the ribs down, lightly brace, and hold a gentle posterior pelvic tilt.
– Keep your pelvis level and low back from arching by stopping the leg raise before the pelvis tips or the back lifts off the floor.
– Limit the height of each raise to a range you can perform without rib flare or pelvic tilt.
– Move slowly and smoothly, pausing briefly with control at the top of each leg raise.
– Maintain a neutral head and neck with your gaze straight up; avoid lifting the head.
– Keep your arms by your sides, palms down, to add stability.
– Inhale to prepare and exhale as you lift the leg, maintaining calm, even breaths as you alternate.
– Keep the working knee straight but not locked, reaching long through the heel.
– Choose a nonworking leg position you can control (heel on the floor or hovering slightly) and switch legs smoothly.
– If hamstring tightness or pelvic motion appears, reduce the raise height or allow a slight knee bend.
Lying Simultaneous Alternating Straight Leg Raise Beginner Introduction
The Lying Simultaneous Alternating Straight Leg Raise is a controlled floor exercise that highlights coordination between the hips and the core. While lying on the back, one long leg travels upward from the hip as the other remains extended closer to the ground, then the roles reverse. The front of the hips drives the lift, while the abs, deep abs, and side abs tighten to hold the hips level and limit extra motion through the lower back and ribs. This creates a strong stability challenge for the midsection rather than a fast, swinging leg raise.
The movement centers on smooth, unhurried leg action through a range that feels manageable, with special attention on a steady trunk, relaxed neck, and calm, regular breathing. Arms resting alongside the body contribute extra balance, allowing more attention on precise hip motion. Because the legs alternate, momentum stays low and body awareness rises, turning a simple lying leg raise into a refined drill for hip control and core steadiness.
