Quarter Sit-Up With Pillow
Quarter Sit-Up With Pillow Exercise Description
The Quarter Sit-up with Pillow is a small-range trunk flexion drill that targets the rectus abdominis with assistance from the external and internal obliques. Using a pillow under the head and neck encourages neutral cervical alignment and keeps the movement focused on a controlled upper‑torso curl rather than a full sit-up. You’ll lift only the head, neck, and shoulder blades, drawing the ribcage toward the pelvis while keeping the pelvis quiet and the lumbar spine from excessively pressing or arching. This shortened range helps you practice precise bracing, rib control, and smooth breathing. Expect a deliberate, minimal arc: just enough to peel the shoulder blades from the floor before returning under control.

How To Do The Quarter Sit-Up With Pillow Exercise
‘- Lie supine with knees bent and feet flat, hip-width apart. Place a small pillow under the head and neck so the face angles slightly forward, not tipped back.
– Set ribs down and lightly brace the abdominal wall. Keep the pelvis neutral; avoid forcefully flattening or arching the low back.
– Place arms across the chest or fingertips lightly at the sides of the head (do not pull on the head).
– Inhale to prepare. Exhale and tuck the chin slightly, then curl head, neck, and shoulder blades up just until the bottom edges of the shoulder blades begin to lift.
– Pause briefly while maintaining rib-to-pelvis tension.
– Inhale and lower slowly to the start, keeping the pillow supporting the head.
– Form checks: keep gaze up, elbows wide if hands are near the head, feet quiet on the floor, and movement smooth without jerking or holding breath.
– If the pillow is too thick to keep a neutral neck, switch to a thinner pillow.
Quarter Sit-Up With Pillow Tips
‘- Position the pillow so your face angles slightly forward, avoiding a tipped-back neck.
– Set your ribs down and lightly brace your abdominal wall before you start curling.
– Keep your pelvis neutral; avoid forcefully flattening or arching your low back.
– Place fingertips lightly at the sides of your head or cross your arms on your chest, and do not pull on your head.
– Exhale as you tuck your chin slightly and curl up, lifting only the head, neck, and shoulder blades.
– Stop curling once the bottom edges of your shoulder blades just begin to lift from the floor.
– Maintain rib-to-pelvis tension during the brief pause at the top.
– Inhale as you lower slowly and smoothly, keeping the pillow supporting your head.
– Keep your gaze up, elbows wide (if hands are near the head), and feet quiet on the floor.
– If your neck doesn’t feel neutral, switch to a thinner pillow to improve alignment.
Quarter Sit-Up With Pillow Beginner Introduction
The Quarter Sit-up with Pillow is a gentle core exercise built around a very small curling motion of the upper body. It is typically performed lying on the back with the knees bent, using a soft cushion behind the head and neck. This support helps the neck stay in a comfortable, aligned position so the effort centers on the abs and side abs rather than straining through the neck. Only the upper part of the spine moves, creating a subtle lift of the chest and shoulders instead of a full sit-up.
During the movement, the rib area glides slightly toward the hips while the hips and lower back remain relatively steady, reducing the urge to push the low back hard into the floor or let it arch dramatically. The path of motion is intentionally small, lifting the upper back just enough for the shoulder area to lightly separate from the ground. This modest range highlights careful core bracing, gentle control of the ribcage, and smooth, unforced breathing. The pillow’s thickness can vary so the neck rests in a natural angle throughout the exercise.
