This little electronic shell-like device is perfect for the office, or really anywhere. It fits in the palm of your hand and enables discreet isometric exercise. Essentially, the device provides resistance during your mini workout, which can target the upper body, thighs or abs, depending on where you put the device. The Wellshell also works with an App to connect users to one another, provide games that correspond with Wellshell workouts and track everything from heart rate to steps. Unfortunately, it’s not out on the market yet and the price hasn’t been announced either.
