Wide Leg Sit-Up
Wide Leg Sit-Up Exercise Description
The wide leg sit-up is a bodyweight trunk-flexion exercise performed with the hips abducted and knees bent wider than the hips. It emphasizes the rectus abdominis while the external and internal obliques assist in controlling rotation and stability; the hip flexors also contribute to the sit-up motion. Working through a smooth curl-up to an upright torso teaches coordinated spinal flexion with controlled hip flexion. Keeping the legs wide can help many lifters feel more stable through the pelvis and reduce the urge to lift the feet or rock for momentum. The goal is crisp, controlled reps that move the rib cage toward the pelvis while maintaining relaxed shoulders and a neutral head/neck position.

How To Do The Wide Leg Sit-Up Exercise
‘- Sit on the floor with knees bent and feet flat, set wider than shoulder width; toes slightly turned out.
– Cross arms on your chest or place fingertips lightly at your temples; avoid pulling on your head.
– Lie back under control until your shoulder blades touch the floor; eyes look straight up.
– Lightly brace the abdomen, ribs down toward the pelvis.
– Exhale and initiate by curling the upper back off the floor, then continue up through a smooth trunk flexion.
– Keep knees dropped outward and feet flat; avoid swinging the arms or jerking.
– Finish tall with the torso stacked over the pelvis, chest open, and neck in line with the spine.
– Inhale and reverse slowly, lowering segment by segment until the shoulder blades touch down.
– Keep motion controlled throughout; stop the range where you can maintain form.
– Common faults to avoid: yanking the neck, bouncing, anchoring the feet if it causes excessive hip-dominant pulling, and letting the low back arch at the bottom.
Wide Leg Sit-Up Tips
‘- Set your feet flat on the floor wider than shoulder width with knees bent and toes slightly turned out.
– Cross your arms on your chest or place fingertips lightly at your temples, and avoid pulling on your head.
– Lie back under control until your shoulder blades touch the floor, keeping your eyes looking straight up.
– Lightly brace the abdomen with the ribs drawn down toward the pelvis before you start the sit-up.
– Exhale and initiate the movement by curling the upper back off the floor, then continue into smooth trunk flexion.
– Keep your knees dropped outward and feet flat, and avoid swinging the arms or jerking to gain momentum.
– Finish tall with the torso stacked over the pelvis, chest open, and neck aligned with the spine.
– Inhale and reverse the motion slowly, lowering segment by segment until the shoulder blades touch down.
– Keep each rep crisp and controlled, moving the rib cage toward the pelvis while maintaining relaxed shoulders and a neutral head/neck.
– Avoid yanking the neck, bouncing, anchoring the feet if it causes excessive hip-dominant pulling, or letting the low back arch at the bottom.
Wide Leg Sit-Up Beginner Introduction
The wide leg sit-up is a bodyweight core movement that blends a curling action of the spine with bending at the hips. The person lies on the floor with the legs set wider than the hips, then rolls the upper body up to a tall seated position and back down again in a smooth, flowing arc. This version directs a lot of work to the abs, with the side abs helping to control any twisting and provide extra steadiness, while the hip flexors assist in lifting the torso.
Setting the knees apart changes how the pelvis feels against the floor, often creating a more grounded base. Many lifters find this wider stance reduces the temptation to rock for momentum or lift the feet. The movement emphasizes deliberate, segmented motion—especially through the spine—so the rib cage and pelvis travel toward each other in a coordinated way. Attention to calm shoulders and a relaxed neck supports a strong, centered core effort throughout each repetition.
