Ab Scissor

Ab Scissors are a simple but effective exercise to work your abdominal muscles. Here's how to do them using only your bodyweight:

1. Lie on your back with your legs straight and your arms extended over your head.
2. Lift your shoulders and legs off the ground slightly and keep them there throughout the movement.
3. Bring your right arm and left leg together in a diagonal motion, as if you were cutting paper with scissors.
4. Return to the starting position and repeat with your left arm and right leg.
5. Alternate sides for 10 to 15 repetitions per set. Do 3 sets with a short rest between them.
