Therefore fitness model and personal trainer Tyler Sarry recommends his exercise "Lower Back Extension on Ball". This exercise shows that you don't need a machine or a barbell to isolate and strengthen this body part. In the video Tyler demonstrates two variations - for beginners and advanced -, and explains in detail how to perform them effectively.
