Lying Raised Shoulders Windshield Wiper
- Intermediate
- Compound
- Rep-based
- Waist
This exercise targets the obliques and rectus abdominis by combining an isometric upper-body crunch with dynamic lower-body rotation. Raising the shoulders increases constant tension in the upper abs while the leg rotation challenges rotational stability and core strength.

Setup
- Lie flat on your back on a mat with your arms extended out to the sides, palms down for stability.
- Lift your legs straight up toward the ceiling until they are perpendicular to the floor, keeping your feet together.
- Lift your head, neck, and shoulder blades off the mat, engaging your upper abs to maintain a 'crunched' position.
How to do it
- Inhale and slowly lower your legs to one side in a controlled arc, going only as far as you can without your opposite shoulder lifting.
- Exhale and use your obliques to pull your legs back to the center starting position.
- Repeat the movement on the opposite side, alternating back and forth while keeping your shoulder blades elevated throughout the set.
- Maintain a controlled 2-second descent and a 1-second return to center.
Form checklist
- Keep your shoulder blades lifted off the floor at all times to maintain upper ab engagement.
- Ensure your legs remain as straight as possible throughout the entire range of motion.
- Keep your arms and palms pressed into the floor to act as an anchor.
- Avoid letting your feet touch the ground at the bottom of the movement.
Pro tips
- Focus on 'pinning' the opposite shoulder to the mat as your legs rotate away to maximize the eccentric stretch on the obliques.
- Squeeze your inner thighs together to stabilize the pelvis and increase lower abdominal recruitment.
Make it harder
- Hold a light medicine ball or yoga block between your ankles to increase the rotational load.
- Slow the tempo to a 4-second descent on each side to maximize time under tension.
