Rolling down into any Pilates-style pushup from above is akin to the Roll-Up, only vertical!
1. Stand tall at the front edge of the mat (facing away) and inhale with control as you bring your arms up, wrapping the thighs together tightly and drawing the abs in and up.
2. Exhale slowly and round forward with control, bringing your palms to the mat. Reach your forehead to your knees.
3. With stiff legs and feet, march your heels backward using just 3 1⁄2 strides to get you down to a rigid plank position ("steel from head to heels").
4. Hold your plank for a count of three, using the time to broaden the chest and press the mat away.
5. Lift from your powerhouse muscles, draw the ribs in, and fold your chest toward your thighs, like an upsidedown Teaser.
6. Lower your heels to the mat and, keeping the knees dead-straight and the feet flexed, walk your feet as far between your hands as possible, scooping your abs to make room for the length of your legs.
7. Roll up to the starting position.
Reps: You get five repetitions to appreciate how hard an elephant works in its abs to manage those stiff legs.
