Tribulus terrestris is the #1 selling testosterone booster, and the best example of a supplement that increases libido, but has no effect on testosterone.
Ab belts may cause muscle contractions if used properly. But the belt alone cannot produce six-pack abs. The real challenge to ab definition is the layer of fat that lies right under the skin, hiding muscle tone.
The Flex Belt will stimulate all your major stomach muscles at the same time providing you with the perfect abdominal contraction â that means your upper abs, the lower abs and even your obliques are going to get worked from The Flex Belt... and it does all the work for you.
