Twisting Crunch
Twisting Crunch Exercise Description
The Twisting Crunch is a bodyweight floor exercise that targets the anterior core, emphasizing the obliques through controlled trunk flexion with rotation. From a standard crunch setup, you lift the shoulder blades and rotate the ribcage toward the opposite hip while keeping the pelvis stable. Primary muscles include the external and internal obliques and rectus abdominis; the deep abdominal wall (transversus abdominis) contributes to trunk stiffness and pelvic control. Using a small, precise range helps focus motion through the upper trunk and reduces hip flexor dominance relative to full sit-ups. Key technique points—posterior pelvic tilt, neutral neck, and elbows kept wide—promote effective abdominal engagement and reduce compensations from pulling the head or hiking the hip. This variation builds rotational flexion control that supports everyday turning tasks and sport-ready torso mechanics.

How To Do The Twisting Crunch Exercise
‘- Lie supine with knees bent ~90 degrees, feet flat hip-width apart.
– Gently posteriorly tilt the pelvis to lightly imprint the lower back on the floor.
– Place fingertips at temples or cross arms on chest; keep elbows wide and neck long.
– Inhale to prepare; on the exhale, draw ribs toward pelvis to lift shoulder blades.
– Rotate through the ribcage (not the hips), bringing right ribcage toward left hip.
– Keep gaze up/diagonal; avoid pulling on the head or collapsing the elbows inward.
– Briefly hold with scapulae off the floor; maintain the pelvic tilt and abdominal brace.
– Lower with control on an inhale, then repeat the rotation to the other side.
Twisting Crunch Tips
‘- Lie supine with knees bent about 90 degrees and feet flat, hip-width apart before starting each rep.
– Gently posteriorly tilt the pelvis to lightly imprint the lower back on the floor and keep this tilt throughout.
– Place fingertips at temples or cross arms on the chest, keeping elbows wide and neck long instead of pulling on the head.
– Inhale to prepare, then exhale as you draw the ribs toward the pelvis to lift the shoulder blades off the floor.
– Use a small, precise range of motion so the movement stays focused through the upper trunk.
– Rotate through the ribcage, not the hips, bringing the right ribcage toward the left hip, then alternating sides.
– Keep the pelvis stable and avoid hiking the hip as you rotate.
– Keep your gaze up or on a diagonal while rotating, rather than collapsing the head forward.
– Briefly hold with the scapulae off the floor, maintaining the pelvic tilt and abdominal brace.
– Lower with control on an inhale before repeating the rotation to the other side.
Twisting Crunch Beginner Introduction
The Twisting Crunch is a bodyweight core move performed on the back, with the upper body curling and rotating at the same time. The motion brings one side of the ribcage toward the opposite hip while the hips stay steady on the floor, so the effort centers on the abs and side abs instead of the hip flexors. A relatively small lifting range places the work in the upper trunk, helping the front of the midsection and the deep abs share the load for stability.
This exercise highlights controlled rotation rather than speed. The lower back rests gently against the ground, the neck stays long, and the elbows remain open so the trunk drives the action instead of the arms or head. A brief pause with the shoulder blades lifted lets the core support the position before lowering with smooth control and rotating to the other side. Over time, this pattern builds confident turning strength that carries over to everyday twisting motions and athletic torso movements.
