Windshield Wiper

  1. Lay on a mat while facing up.

  2. Lift the legs with a 90 degree angle at the hips and the knees.

  3. Keep both shoulders flat on the mat for the entire exercise.

  4. Slowly arc the knees from left to right and repeat. Exhale as the knees are closing in on the ground.

  5. Simply go to your comfortable range of motion, instead of trying to force yourself to touching the floor for every repetition.
