Roll-out with Isometric Hold
The traditional barbell roll-out is a great anti-extension exercise for the abdominal/lumbar region. This exercise can also be done with your elbows on a yoga ball or using an ab wheel. You should only perform this exercise if you have been taught how to create proper abdominal stiffness under tension. If you do not stay braced and let your hips fall, you will likely feel this exercise in your lower back. Once you have mastered the traditional movement, you can introduce novelty and increased difficulty with an isometric hold towards the end range.
