The Ab Lounge Chair is a revolutionary new ab machine that tightens and tones upper and lower abs and obliques faster than you ever imagined possible! The machine works your abdominal muscles   with a fuller range of motion than crunches or sit-ups, and the   fuller the range, the longer your abs are toning and tightening. The Ab Lounge Chair also strengthens your back muscles where your functional   strength originates. A stronger core gives you greater everyday   strength, with less strain on your body and back. Built to last with   a rolled steel frame, the Ab Lounge Chair can support up to 250 lbs.   Includes a workout video and healthy eating guide filled with diet   tips and recipes.
