Floor windshield wipers

Instructions

Lie on your back, arms stretched on the sides, legs stretched and joined. Raise your legs slightly off the floor. This is the starting position.
While trying to keep your legs together, stretched and close to the floor (without touching it), move them to the left until they form almost a 90-degree angle with your bust. Your hips will rotate and your lower back will come off the floor but the upper body should stay stationary.
Return to the starting position, then make the same movement on the right side.
