To use the ProForm Ab Glider, you start by kneeling on a pad and grasping the handles in front of you. This knee pad is mounted onto a curved track that also can swivel.
The arc movement is initiated by your grasping the two handles to pull yourself along the track and also by twisting.
By also twisting your body, you can swivel the track as you glide along it to work your all of your abdominals, including the oblique’s (love handle area). And by having this unique track swivel, in addition to the forward and backward motions, this ab machine works on all areas of your abs by engaging your entire core in one wave.
