Kneel onthe floor/mat and grasp the barbell with a wider than shoulder width grip. You should have 5-10 lb plates loaded on each side of the barbell.

Keeping your back and arms straight, slowly roll the barbell out in front of you until your arms are fully extended.

Tense the abs and slowly roll the barbell back towards your knees.

Ab Rollout Tips:

Keep your arms and back straight at all times.

Do the exercise slowly, and concentrate on using your abdominal muscles to pull the barbell back towards you.

For extra intensity barbell rollouts can be done standing.
