How to do it
Initiate each rotation from your hips rather than twisting your spine.
- 1
Lie on your back with your arms extended to the sides for stability.
- 2
Lift your legs off the ground and keep them straight, forming a 90-degree angle with your torso.
- 3
Without bending your knees, rotate your legs from side to side in a 'wiper' motion.
- 4
Keep the movement controlled and your core engaged to prevent your legs from touching the ground.
- 5
Continue the wiper motion for the desired duration or number of repetitions.
Expert tip
Keep your arms fully extended and your body in a straight line to maintain tension on your core and upper body throughout the exercise.
