Here is another personal fitness device that helps you burn calories, tone your body, and access your stats on your smartphone. VHOOP is a connected hula hop with 8 pieces that you can put together or take apart easily. You will be able to see the number of rotations, calories burned, and length of your workouts in real-time on your phone.
VHOOP can be used for over 2 weeks on a fully charged battery. Its sensors help you get a more balanced workout on all sides. You can add 8 stainless steel weights to do more with this.
