The innovative exercise machine will allow you to exercise and workout anywhere! don't let the small size fool you.
Pick one up, spin it up to 10,000+ RPM and you'll be amazed by the amount of physical work required to keep it spinning at speed, using such a small compact motion.
Go ahead, feel the burning forearm after a minute of use. Because the resistance is provided by angular momentum built up through a spinning mass, a few minutes a day on our spinner can be equivalent to hours of full motion work with a dumbbell or a Curl.
