How to Do Sit-Ups

  • Lie on your back, with your hands in front of your chest and your knees bent to about 90 degrees. Use a weight or something to stick your feet under, so they don’t lift from the ground.
  • Lift your upper body by contracting your abs and bending forward.
  • Bend as far forward as possible, and then return to the starting position.


The sit-up is a classic body weight exercise for strengthening your abs. You can increase the load by holding a weight against your chest.
