Muscle Groups
  • Abs and Core
  • Abdominal strength


The leg-tucked medicine “med” ball crunch strengthens the abdominals and obliques. The med ball makes flexion of the spine more difficult, therefore increasing the difficulty of the exercise. Depending on your goals – choose a lighter ball for muscular endurance or a heavier one for muscular strength. The leg-tucked position decreases the hip flexor involvement.


  • Lie on your back with your legs tucked up, feet off the floor.
  • Hold the medicine ball at your chest, close to the chin.
  • Keeping your neck neutral, roll your upper back off the floor.
  • Return slowly to the floor.


  • Jutting the chin as you crunch up
  • Holding the medicine ball too low toward the stomach
