The Plank is an excellent core exercise and test of core strength, this version of that exercise is more advanced.
- Start this exercise by lying face down on a mat. Arms outstretched but slightly bent, legs straight and up on your toes.
- Using your toes and abdominals, lift your body off the mat a few inches with only your toes and forearms touching the mat.
- Hold for 2 seconds and release back down to start position for one rep.
- Do 10-12 reps to start, and increase as you progress.
