9. Starfish with push-up
Get into the push-up position, shift your weight to your right-hand hand, and stretch your left arm straight up.
Your body forms straight lines from head to heels and palm to palm. Raise your upper body slightly and rotate your hips forward.
Then bring your left arm back to the push-up position and complete a push-up by bending your elbows, lowering your chest, and pressing back up.
Repeat the exercise on the other side.
