YBR Abdominal Strengthening Routines on DVD. No more crunches! YBR will strengthen your abs without tightening and shortening these muscles. We promise you not just longer, stronger abs but a longer, leaner torso, too. Meanwhile, you’ll develop greater core strength and your belly will flatten in the most wonderful way!
YBR ABDOMINAL STRENGTHENING DVD is our beginning work for understanding how to work your abdominal muscles correctly. We help you to build long strong abdominal muscles and teach you how to connect your abdominal muscles to your spine to help build a strong lower back.
