Step 1: Start in an all-fours position on the floor with your arms straight, your knees directly below your hips, and a straight back (neither sagging nor arching).

Step 2: Keep one hand on the floor, then sweep your other arm toward the ceiling while turning your head to follow your hand. Hold for three seconds.

Step 3: Bring your arm back down and slide it underneath your upper body until your shoulder touches the floor.

Step 4: Return to the starting position, then repeat on the other side. Do 10 repetitions on each side.

While you can perform this exercise with alternating arm movements, it can get confusing. Instead, you may prefer to do 10 repetitions on each side.
