Straight-leg sling sit-ups develop power in the core and upper-body. Straight-leg sling sit-ups require more hip flexor strength than the Bent-knee sling sit-ups. Perform this exercise only if you have no back injuries or pain. This is a good exercise for anyone looking to take their ab training to the next level.


  • Sit on the floor with your legs in fron of you, knees straight.
  • Roll your body back and down, stretching your arms behind your head.
  • Then throw your arms up and toward your legs while sitting up.
  • Repeat for a specified number of reps.


  • Not throwing the arms fast enough to create momentum to assist with sitting up.
  • Letting the chin jut out (instead of staying tucked).
  • Feet rising from the floor.
