Considering the seeming cornucopia of muscle ripping machines - from the simple to the ridiculous - being endlessly paraded on commercial media, there must be an incredible niche market out there.
Must admit: I have a plastic, concave looking thing stuffed behind the desk, designed for facilitating crunches. It actually does work and comes in it very handy when I get the notion, perhaps once a year, if that often. Seems a day up and down on the ladder involves the equivalent of several workouts, but realize that can be pure deception.
Do you find yourself occasionally stumbling over finely-engineered apparatuses folded neatly in closets, under the bed or in catch-all rooms, designed for the ever illusive, ripping abs?
