Reverse plank elbows is a variation of the reverse plank that adds an extra challenge to the upper body and core. By bending and straightening your elbows, you engage the triceps, shoulders, and core muscles, enhancing overall upper body strength and stability.

1. Sit on the ground with your legs extended and your hands placed slightly behind you, fingers pointing towards your feet.
2. Lift your hips off the ground, forming a straight line from your head to your heels.
3. Bend your elbows, lowering your upper body towards the ground while keeping your hips elevated.
4. Straighten your arms to return to the starting position.
