Core: Reverse Crunch
- Lie on your back on the floor. Place your hands on the floor beside you.
- Bring the knees in toward the chest with your feet together.
- Use your abs to slowly curl the hips off the floor and into your chest, and then slowly lower them back to the starting position to complete one.
- Repeat for one minute. Don't swing your legs to create momentum; use your abs to control your movement.
