How to do it

Sit on the floor with your feet anchored under a heavy object or held in place. Lower your torso back toward the floor, then drive up through a full sit-up and continue the momentum to rise into a standing position. Sit back down and repeat.

  1. 1Feel your abs and hip flexors drive your torso up off the floor
  2. 2Use a controlled surge to carry you up to standing
  3. 3Keep your core braced as you transition from seated to standing

Common mistakes

  • Don't yank your neck or throw your head forward
  • Avoid collapsing back down without control
  • Don't let your lower back round harshly at the bottom
