- Start in a plank position with a glider underneath each foot. If you don't have gliders, you can use a towel on a hard surface to perform this exercise.
- Engage your core and bring both knees in, toward your elbows. With control, return to the starting position. Then, raise your hips as high as they can go. Your core should be engaged and your back should be in a neutral position throughout the entire movement.
- This counts as one rep.
- Complete as many reps as you can in 45 seconds, then rest for 15 seconds.
