Does the Ab Trainer come with any exercise?
The Athlos Fitness Ab Trainer does not come with any exercise. Essentially, It's a tool to give you full range of motion when doing sit-ups. If you are looking for an exercise scheme, for beginners I would recommend 4 sets of 15 reps. For more advanced, 4 sets of 25 reps; from that point I would build up the reps to your fitness level.
