Knockout Abs 

Knockout ABS gives you a total body workout, combining cardio and core strength training for maximum results in minimal time!
In just minutes a day you can crunch and punch your way to six pack ABS as you get a fat burning cardio with the waist trimming abdominal workout all in one simple to use machine.
It uses proven techniques that boxers use to maintain a strong and powerful core known as the 3 C's 'continuous core cardio' - the unique crunch and punch motion engages multiple muscle groups while working your heart at the same time so your total body gets to the fat burning zone faster than you ever thought possible.
A fully adjustable padded crossbar and cushioned seat firmly supports your knees while your own weight holds you in place, allowing you to do the perfect sit up.
