This 5-move routine will prepare you for the ultimate core exercise.
A combination of an X plank and superman, the exercise is performed by getting in a plank position with your feet wide apart, then walking your hands out and slightly forward so that your body forms an X. After holding for 10 seconds, you lower down to the floor, arms extended overhead, palms facing the floor, and legs extended behind you.
You then raise your arms and legs as high as you can, bring your arms out to your sides and behind you as you turn your palms toward the ceiling. At the end of each rep, you return to the start position.
The exercises in the slideshow below help you build up to the mission impossible. Complete the routine 2 to 3 times per week on nonconsecutive days for optimal results.
