Most ab stimulators are adhesive pieces of cloth that a person sticks to their abs. Each portion of the cloth delivers an electric current to the abdominal muscles, causing contractions that a person might not even feel. Some stimulators are belts that require no adhesive and wrap around the body.

Do Ab Stimulators Really Work?

Ab stimulators, a type of electronic muscle stimulator, are devices that can make your abdominal muscles appear firmer and more toned by electronically stimulating them. However, they won't help you lose weight, or get “rock hard” abs without diet and exercise.

How long does it take for the AB stimulator to work?

Although it's better than nothing, and although it does specifically target your abs, you're not going to notice a difference right away. After at least 2 months, you will likely notice a difference in abdominal strength and endurance as well as the appearance of your midsection.
