Ab Swing -
How it works! The makers of Ab Swing cal it 'Swing Glide' technology. It contracts your abs from the lower abs up. The design puts you in an upright position, off the floor. This position is natural and provides an expanded full range of motion. Your muscles flex and stretch in a single movement. Plus the abdominal muscles are isolated! You target your lower abs, upper abs, and side obliques, while stretching your lower back.
