Instructions for Oblique Crunch

To perform a set of oblique crunch:

  1. Starting Position

    Lie supine on a mat with your knees bent, feet on the ground and left hand beside your ear. The trunk should be in a neutral position.

  2. Concentric (Upward) Motion

    Squeeze your abdominals to raise your left shoulder and head off the ground until your shoulder blade lose contact with the mat. It is important to breathe normally and maintain a neutral lower back position throughout the entire movement.

  3. Top position

    Pause at the top position for a 1sec count while squeezing your abdominals.

  4. Eccentric (Lowering) Motion

    Lower your shoulder and head back to the ground without losing the neutral postion of your lower back. Remember to breathe normally throughout the entire movement.

  5. End position

    Repeat steps 1 through 4 until you have completed the desired number of oblique crunch repetitions for each side before resting.

This completes one set of oblique crunch.
