Lying Alternate Straight Leg Lift

Lying Alternate Straight Leg Lift Exercise Description

The Lying Alternate Straight Leg Lift is a supine, bodyweight hip-flexion exercise performed one side at a time while the trunk stabilizes. Primary movers are the iliopsoas and rectus femoris, with assistance from the sartorius and tensor fasciae latae; the abdominal wall (rectus abdominis and obliques) works isometrically to resist anterior pelvic tilt and lumbar extension. Alternating legs emphasizes unilateral control and helps you monitor symmetry without the momentum often seen in two-leg raises. Keep the motion slow, controlled, and within a range that allows the pelvis to stay level and the lower back to remain stable. Proper execution reinforces lumbopelvic control and clean hip mechanics.

How To Do The Lying Alternate Straight Leg Lift Exercise

‘- Lie on your back with legs long, feet hip-width, arms by your sides, palms down.
– Set a neutral spine: ribs gently down, brace the abdominal wall, and keep the pelvis level.
– Keep both knees straight (not locked) and toes pointing up.
– Press the nonworking leg lightly into the floor to create a stable base.
– Without moving your pelvis, lift one straight leg until just before your lower back wants to arch.
– Pause briefly, keeping the knee extended and thigh aligned with the pelvis.
– Lower the leg with control to the floor or a light hover—no bouncing.
– Alternate sides smoothly, maintaining the same range and tempo.
– Keep your neck relaxed, gaze up, and shoulders down.
– Breathe continuously—exhale during the lift, inhale as you lower.

Lying Alternate Straight Leg Lift Tips

‘- Set a neutral spine by gently dropping the ribs, bracing the abdominal wall, and keeping the pelvis level.
– Keep both knees straight but not locked, with toes pointing straight up throughout the movement.
– Press the nonworking leg lightly into the floor to create a stable base before lifting the other leg.
– Lift the working leg slowly and stop just before your lower back wants to arch to keep the pelvis and lumbar spine stable.
– Pause briefly at the top with the knee extended and the thigh aligned with the pelvis.
– Lower the leg with control to the floor or a light hover, avoiding any bounce.
– Alternate legs smoothly, matching the same range of motion and tempo on both sides to monitor symmetry.
– Keep your neck relaxed, gaze directed up, and shoulders down against the floor.
– Breathe continuously—exhale as you lift the leg and inhale as you lower it.

Lying Alternate Straight Leg Lift Beginner Introduction

The Lying Alternate Straight Leg Lift is a floor-based movement that highlights hip motion while the midsection works to hold the body steady. The person lies on their back and raises one straight leg at a time, with the other leg staying long on the ground. This pattern places the effort mainly on the hip flexors and the front of the thigh, while the abs and side abs create a firm, braced feeling through the center of the body.

Because the legs move one at a time, the exercise draws attention to differences between sides and encourages even control. The pelvis and lower back are meant to stay calm and steady while the leg travels, which promotes a strong connection between the hips, core, and spine. The movement favors a smooth, unhurried style and a leg height that allows the low back to remain quiet. Steady breathing and relaxed shoulders round out the overall theme of stability, precision, and clean hip action.
