How to do it

Set up on the floor or a bench with your spine flexed and shoulders rounded forward. Slowly extend your spine one vertebra at a time, rolling up through a rounded back until you reach a tall, extended position. Lower back down with control, articulating through the spine each rep.

  1. 1Feel your lower back and spinal muscles roll you up segment by segment
  2. 2Keep the movement slow and articulate through the whole spine
  3. 3Let the contraction build in your lower back and glutes at the top

Common mistakes

  • Don't snap or thrust your spine backward at the top
  • Avoid using momentum; control each segment of the roll
  • Don't hyperextend hard past a neutral tall position
