@carlosmurray706: Are you using your ab trainer wrong? Here's how to use the Merach Ab Trainer Pro with proper form: chest down, back slightly rounded, and eyes on your knees. This foldable ab machine has an LCD monitor to track every rep during a quick 10-minute core workout at home. Great home gym equipment for men and women who want to work their abs and obliques, no gym needed. @MERACH
