@carlosmurray706: Husband vs. wife ab challenge! Who can get the most reps in 30 seconds on the Merach Ab Trainer Pro? We used the harder discs-to-the-side method to work our abs and obliques, and the LCD monitor tracked every rep. This foldable ab machine makes a fun couples workout and an easy at-home core workout. Great home gym equipment for men and women who want to stay consistent, no gym needed. Who do you think won? @MERACH
