Here is a smart wearable device that uses electrical muscle stimulation to tone your hips and thigh muscles. The SixPad Bottom Belt comes with two thigh bands and in 3 sizes. It delivers 20Hz pulse in 23-minute programs to work your body. The high-conductivity electrode gel pads last for 2 months.
You can interact with the belt from your iOS or Android device. The bad news? Something like this doesn’t come cheap. More info is available here.
