Exercise Summary

Exercise Name: Decline Oblique Crunch
Main Muscle: Obliques
Secondary Muscle(s): Abs
Equipment Required: *N/A

*This oblique exercise is pictured below on a decline bench; however, a decline bench is not required as this exercise is generally done on flat ground or an exercise mat. The incline simply increases the difficulty level. See the oblique crunches exercise instruction guide for more information.

Exercise Description and Instruction:

This exercise works the abdominals as well as your obliques, the muscles on the sides of your abs. The obliques and abs are commonly worked together.

To Perform this Exercise:

  1. Lie on a decline bench face up and place your feet securely under the pads. You can make the exercise easier by performing it on flat ground or an exercise mat.
  2. Place your hands either across your chest or on either side of your head.
  3. Raise your shoulders and chest up keeping your back straight and bring your left elbow to your right knee, slowly crunching your abs.
  4. Pause for a moment and then return to the starting position. Lay fully back and repeat with your right elbow to your left knee.


  1. Picture your abdominals and obliques compressing like an accordian as you complete the crunch.
  2. Hold a dumbbell, weight plate, or medicine ball behind your head for added resistance. Be sure that your form is not compromised.
