Here is a useful gadget for people who like working out from home.  Meet ZeroWheel, a motor-powered home gym accessory that can train arms, quads, glutes, abs and many more muscle groups.

ZeroWheel looks like an ab roller but wait, it has more technology than you can guess. The ZeroWheel features a powerful motor that offers 5 levels of resistance, as well as LED lights on either side of the wheel. It also connects to your smartphone and provides you with insights and workout information. There are four main modes to choose from, including burn, aerobic, assistance, and resistance.

The motor is smart enough to provide you assistance during your exercises. It is like a spotter in the gym. In the resistance mode, the motor works against you, offering more resistance. The product is portable but not very lightweight. I heard from their team that the final version is going to be lighter than the one I tested.
