A great exercise because it does not only target the abdominal muscles, but also the oblique muscles which run along the side of your ribcage. This makes it an excellent exercise if you are looking for a total core workout. It is not only effective in strengthening abdominal muscles, but can also aid in the treatment and prevention of lower back pain.

How to do:

  1. Lie flat on the floor (on a mat)
  2. Cross at a diagonal in front of your body, bringing your right elbow towards your left knee. Slowly lower your upper body back to the ground. Repeat the maneuver, but this time bring your left elbow to your right knee.

Bring your shoulder up towards your knee rather than just your elbow and remember that the key is to contract the abs as you perform the movement; not just to move the elbow.
