How to Do Oblique Sit-Ups

  1. Lie on your back, with your hands behind your head, and your legs bent to about 90 degrees. Use a weight or something to stick your feet under, so they don’t lift from the ground.
  2. Lift your upper body diagonally by contracting your obliques and bending forward, until your right elbow touches your left leg, or vice versa.
  3. Return to the starting position.


The sit-up is a classic body weight exercise for strengthening your abs. This is a variant of the sit-up that targets the obliques.
