Begin lying on your side with your bottom leg straight, your top leg bent at a 90-degree angle, and your arms straight on the ground together
Slowly move your top arm away from your other arm, toward the floor on the other side, rotating your trunk at the same time
Make sure to keep your top leg on the floor and only go as far as you can without needing to arch your back
After finishing the set on one side, repeat the same on the other side
