Alternate Leg Raise With Head-Up

Alternate Leg Raise With Head-Up Exercise Description

The Alternate Leg Raise with Head-up is a supine core drill that trains anterior core control while the hip flexors move the legs. One leg lifts while the other stays long on the floor, and the trunk resists arching or tilting. The rectus abdominis works isometrically to limit lumbar extension, with the obliques and transverse abdominis assisting in bracing; the hip flexors (including iliopsoas and rectus femoris) are the primary movers. Lifting the head and upper shoulders slightly creates gentle trunk flexion, which can help maintain a stable pelvis; keeping the neck long and the chin lightly tucked is key. The goal is smooth, controlled leg motion with a steady torso—no rib flare, no low‑back lift, and no momentum. If neck discomfort is present, the head may stay down while preserving the same trunk position and control.

How To Do The Alternate Leg Raise With Head-Up Exercise

‘- Lie on your back, legs long, feet hip‑width, arms by your sides, palms down.
– Brace your abdominal wall; draw the ribs down and set a slight posterior pelvic tilt (or neutral without arching).
– Light chin nod; lift head and shoulder blades just off the floor, eyes to the ceiling.
– Keep both knees extended and ankles relaxed; press the down leg gently into the floor.
– Inhale to prepare; exhale as you raise one straight leg, pelvis quiet and ribs down.
– Lift only as high as you can without low‑back arching or pelvic movement.
– Pause briefly; lower the leg with control, maintaining the same trunk position.
– Alternate legs smoothly while keeping steady breathing and a relaxed neck/face.
– Avoid: jerking the leg, letting the ribs flare, pulling the head forward, or bending the knees.
– Option: keep the head on the floor or reduce range if the neck or low back cannot stay stable.

Alternate Leg Raise With Head-Up Tips

‘- Before moving your legs, brace your abdominal wall and draw your ribs down to set a slight posterior pelvic tilt or neutral spine without arching.
– Keep your neck long with a light chin nod, lifting your head and shoulder blades just off the floor while your eyes look to the ceiling.
– Maintain both knees fully extended and ankles relaxed throughout the movement.
– Gently press the down leg into the floor to help keep the pelvis quiet as the other leg lifts.
– Inhale to prepare, then exhale as you raise one straight leg, keeping your pelvis steady and ribs down.
– Lift the leg only as high as you can without your low back arching, ribs flaring, or the pelvis moving.
– Pause briefly at the top, then lower the leg with control while keeping the same trunk position.
– Alternate legs smoothly, avoiding any jerking or use of momentum.
– Keep your neck and face relaxed; avoid pulling the head forward as you move your legs.
– If your neck or low back cannot stay stable, keep your head on the floor or reduce your leg range of motion.

Alternate Leg Raise With Head-Up Beginner Introduction

The Alternate Leg Raise with Head-up is a floor-based core exercise that combines steady abdominal tension with smooth leg movement. The body is positioned on the back with the legs extended, while one leg lifts and the other remains stretched out along the ground. The abs, deep core, and side abs work together to keep the lower back from bowing upward or the hips rocking, while the hip flexors drive the motion of the lifting leg. The head and upper shoulders hover slightly off the floor, creating a gentle curl through the trunk that supports a stable midsection.

This drill emphasizes control over speed. The raised leg moves in a slow, deliberate path, and the grounded leg presses lightly into the floor for added stability. Breathing stays steady so the torso remains quiet and the movement feels fluid rather than jerky. For those who notice strain in the neck, the same pattern of leg motion and core engagement is often performed with the head relaxed on the floor, with a smaller leg-lift range that still preserves solid trunk alignment.
