There are plenty of ab workout belts on the market. Not everyone is sold on their effectiveness. If you are getting one, you may as well invest in an app-enabled version. The Slendertone Connect Abs is a smart core toning device that connects to your smartphone via Bluetooth. To get started, just download the app, put the belt on, and control your sessions from your iOS device.
After 30 minutes, you get the equivalent of up to 200 muscle contractions. You get alerts to ensure you don’t miss a session. More information is available here.
