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.
You can also multi-task by doing ab contractions at your desk, in the car or while grocery shopping. Think of keeping your abs âzipped upâ while you walk for 30 minutes, three times a week. Cardio and strength training are ways to lose belly fat -- no belt required.
