Pulse Up

This core exercise helps you sculpt six-pack abs. Be careful not to overextend hips or put too much pressure on your lower back.
Start
Pulse Up
  1. Lie faceup on floor with legs extended and together, arms extended by sides.
  2. Lift legs straight up toward ceiling, directly over hips.
  3. Engage your abs as you flex your glutes and lift your hips a few inches off the floor; lower hips to return to start.
