Bolster Crunch

[Elite_video_player id=”30″]

Muscle Groups
  • Abs and Core
  • Abdominal strength


The floor crunch performed on a bolster or with a rolled-up towel develops abdominal strength. Using a bolster allows for increased range-of-motion (ROM) and therefore greater activation of the abdominals. The obliques are also engaged in the floor crunch although to a lesser degree than the abdominals.


  • Lie on your back and place a small rolled-up towel under the small of your lower back.
  • Place your feet flat on the floor about 12 inches apart and your finger tips to the sides of your head.
  • Keeping your neck neutral, push your back into the rolled-up towel and roll your upper back off the ground.
  • Return slowly to the starting position.


  • Jutting the chin as you crunch up
  • Yanking the head up with the hands
