Here is a smart wearable device designed to stimulate your muscles, maximize your workouts, and help you recover faster. The PowerDot Muscle Stimulator comes with slim electrode pads that you can wear comfortably. The device uses electronic pulses to reduce muscular tension, stimulate blood circulation, and speed up recovery times. You can use these on your abs, quads, calves, and glutes.
This kit uses EMS to engage your muscles. The companion app has a bunch of preset programs to get you started. Not cheap though.
