The Ab Flyer is a revolutionary exercise device that is taking abdominal training in a whole new direction. Unlike traditional crunches, which work your abs from the "top down," the Ab Flyer works your abs from the "bottom up," while limiting stress to your neck , back and shoulders.Gymnasts and bodybuilders have known this secret for years: to get a strong, lean core necessary for competition, they work their abs from the bottom up.The Hanging Leg Raise is a "bottom up" exercise that is highly effective for developing great abs.But it is a very difficult exercise to perform. Here's why. The exercise requires not only tremendous upper body strength to hang from a bar, but it also requires you to perform a lower abdominal contraction while lifting the entire weight of your lower body.This exercise sounds hard because it is hard.

The free motion seat adjusts to target your obliques at every angle for a complete abdominal workout.The Ab Flyer is built with the highest quality materials, yet it can be folded in seconds so you can store it almost anywhere from the closet to under the bed and is ready when and where you are!
