Setup
- Lie flat on your back on a mat with your legs fully extended and feet together.
- Place your arms out to the sides at a 45-degree angle, palms down, to provide a stable base.
- Press your lower back firmly into the floor to engage your deep core and eliminate any arching.
- Lift your feet 3-6 inches off the ground to reach the starting position.
How to do it
- Inhale and sweep your legs in a wide, controlled arc to one side, keeping them straight and hovering just above the floor.
- Exhale as you pull your legs back through the center and over to the opposite side in a continuous 'swiping' motion.
- Maintain a steady tempo, taking approximately 2 seconds to complete each lateral sweep.
- Keep your shoulder blades and upper back pinned to the floor throughout the entire movement.
Form checklist
- Keep the lower back glued to the mat; if it lifts, reduce the range of motion.
- Maintain fully extended legs with toes pointed to maximize the lever length.
- Ensure the movement comes from the hips and core, not by swinging the upper body.
- Keep your neck relaxed and gaze toward the ceiling to avoid cervical strain.
Pro tips
- Visualize drawing a wide 'U' shape or a 'smiley face' with your toes to ensure you are hitting the full lateral range of the obliques.
- Focus on the mind-muscle connection by 'pulling' your legs across with your side-abs rather than just moving your feet.
Make it harder
- Slow the tempo down to a 4-second sweep to significantly increase time under tension.
- Hold a light medicine ball or yoga block between your ankles to add resistance and engage the adductors.
