Lying Abdominal Scissors Crunch
Lying Abdominal Scissors Crunch Exercise Description
The Lying Abdominal Scissors Crunch is a bodyweight core exercise that blends a small, controlled crunch with a scissoring leg action. It targets the rectus abdominis through trunk flexion while the hip flexors (iliopsoas and rectus femoris) move the legs; the external obliques and deep abdominal wall assist by stabilizing the pelvis and resisting lumbar extension. The primary objective is maintaining rib‑to‑pelvis control and a steady pelvis as the legs alternate, preventing the low back from arching. Because the head and shoulder blades are lifted, the abdominal wall remains engaged isometrically while the legs create a dynamic challenge. Use smooth, deliberate motion and prioritize spinal position over leg amplitude to keep the exercise focused on the anterior core.

How To Do The Lying Abdominal Scissors Crunch Exercise
‘- Lie supine with legs extended and heels together; place arms by your sides or lightly support your head with fingertips (avoid pulling).
– Exhale, brace the abdomen, and posteriorly tilt the pelvis to gently press the low back toward the floor (“ribs down”).
– Lift the head and shoulder blades slightly, keeping the neck long and eyes toward the ceiling.
– Raise both straight legs a few inches off the floor while keeping the low back in contact; if the back arches, lift the legs higher.
– Begin the scissor: cross one straight leg over the other at mid‑thigh, then alternate which leg is on top in a small, controlled rhythm.
– Move from the hips, keep knees extended and toes relaxed; avoid swinging or bouncing.
– Maintain steady breathing; do not hold your breath.
– Keep the pelvis level—no rocking or tipping—and avoid letting the ribs flare or the chin jut forward.
– To finish, pause the legs, lower them to the floor under control, then return the shoulder blades and head to the mat.
Lying Abdominal Scissors Crunch Tips
‘- Gently press your low back toward the floor by exhaling, bracing, and tipping the pelvis posteriorly (“ribs down”) before you lift.
– Keep your head and shoulder blades just slightly lifted with the neck long and eyes toward the ceiling.
– Raise both straight legs only a few inches off the floor while keeping your low back in contact.
– If your low back starts to arch, lift your legs a bit higher to regain contact with the floor.
– Cross the legs at about mid‑thigh and switch which leg is on top in a small, controlled rhythm.
– Move the legs from the hips while keeping the knees extended and toes relaxed.
– Avoid swinging or bouncing the legs; use smooth, deliberate motion.
– Keep the pelvis level and steady so it doesn’t rock or tip as the legs scissor.
– Prevent the ribs from flaring and the chin from jutting forward as you hold the crunch.
– Maintain steady breathing throughout instead of holding your breath.
Lying Abdominal Scissors Crunch Beginner Introduction
The Lying Abdominal Scissors Crunch is a floor-based, bodyweight core move that combines a gentle upper‑body curl with a precise, alternating leg pattern. The abs create a slight forward bend of the torso, while the hip flexors guide the straight legs as they cross over one another. Side abs and the deeper core muscles play a supporting role by steadying the midsection and helping the lower back stay comfortably supported against the ground.
Because the head and shoulder blades remain lightly lifted, the front of the waist works continuously, holding the trunk position while the legs provide a shifting challenge. The main theme of the exercise is control: a calm, organized center, a quiet pelvis, and legs moving in a smooth, modest range instead of big, swinging motions. This creates a blend of isometric work for the abs and dynamic work for the legs, highlighting ribcage and pelvic stability for anyone looking to emphasize the front of the core in a lying position.
