Muscle Groups
  • Abs and Core
  • Abdominal strength


The leg-tucked crunch is a good beginner exercise for developing abdominal strength. The leg-tucked position lessens the load on the low-back and decreases the hip flexor involvement. The abdominals and obliques flex the spine and should be trained along with the low-back muscles if you desire a strong core.


  • Lie on your back and place your finger tips on the sides of your head.
  • Tuck your legs up, bending at the hips and knees, and keep them in this position.
  • Keeping your neck neutral, roll your upper back off the floor.
  • Return slowly to the floor.


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