Jerry Rice recommends the Flex Belt
“The first time that I used it I was very surprised because it was working those muscles that I had been trying to work with crunches and I got the results that I wanted.  It works those muscles, tones them, makes them stronger and it is very easy.” – Jerry Rice, San Francisco 49ers All Star
