Barbell Ab Rollout - On Knees
A expert strength exercise for the abs, done with a barbell.


How to do the Barbell Ab Rollout - On Knees
- Hold an Olympic barbell loaded with 5-10lbs on each side and kneel on the floor.
- Now place the barbell on the floor in front of you so that you are on all your hands and knees (as in a kneeling push up position). This will be your starting position.
- Slowly roll the barbell straight forward, stretching your body into a straight position. Tip: Go down as far as you can without touching the floor with your body. Breathe in during this portion of the movement.
- After a second pause at the stretched position, start pulling yourself back to the starting position as you breathe out. Tip: Go slowly and keep your abs tight at all times.
