I have the hug all the time and I am really hesitant when it comes to gadgets like this. I personally wouldn't even consider it based on that. Heck, I don't even do regular sit ups anymore as it irritates the hug too much.

I'm glad you decided to reconsider. I always think of all these silly gadgets out there and then think of life before all this technology. Good old fashioned hard physical work kept everyone in shape.
