Aerobic Training Machines

More effective than standard sit-ups or bent knee crunches, the Ab Lounge Sport delivers an effective ab workout for people of all fitness levels. The Ab Lounge Sport is designed to tighten and tone your upper abs, lower abs, and obliques faster than you ever thought possible, with an advanced jackknife design that's far more efficient than traditional ab exercises. The jackknife design works your ab muscles with a complete range of motion, toning and tightening your abs for long periods during each jackknife rep. As a result, the chair elicits more muscle activity in your upper and lower abdominals, helping transform flabby abs and love handles into a sensationally sexy swimsuit stomach. The Ab Lounge Sport also strengthens such core muscles as your abs and back, where your functional strength originates. And thanks to the well-designed steel, plastic, and fabric frame, you'll enjoy plenty of support for your head, neck, and back throughout the entire exercise, so you won't accidentally strain a non-ab muscle through poor form. Other details include a foldable frame for easy storage and a weight limit of 275 pounds.
