|The Lean Abs Machine allows for use at most levels of training because of the comfortably position angled handles, the cushioned Support Pad that allows support down to a users elbows and the Motion Arm is adjustable to decrease the degree of the Lean. You also may add assistance by adding Rubber Tension Weights between the Motion Arm and the Base Frame. Tougher users may place the Rubber Tension Weights between the Motion Arm and the Front of the exerciser to increase the tension to more than just body weight resistance. They also may choose not to use any forearm support at all on the lean out and return.
The Lean Abs Machine development and extreme testing took many years. The angled shoulder width handles were on the first testing but the exercise was still a little too hard for most users. Because the pivot is the ball of your feet we gained an additional 2 feet of leaning body weight resistance when compared to the ab wheel exercise (unless you are strong enough to do the wheel pivoting on your toes with out causing back problems). The developer tested it and had others tested it to get opinions. One guy said, "Hey you know what would be nice? If you had support for your forearms." Many designs were tried until the developer came up with the well balanced and angled just right Support Handle that is being used today. The Abdominal Lean, Obliques Lean exercise, Reversed Angled Leg Squat, Leg Extension and the Angled Calf Raises are incredibly excellent new exercise movements.
Testing was done in a rehabilitation clinic, a full commercial gym location, EMG tested at a university, and in circuit training classes and in homes.
