OYO provides fitness solutions you can use wherever you are right now - home, office, on the go and in OYO Group Exercise classes. The OYO Gym is a total body portable gym powered by SpiraFlex resistance technology used by NASA astronauts on the International Space Station. In a NASA study, SpiraFlex produced the same benefits as free-weights without the need for gravity. The OYO Gym applies SpiraFlex resistance to opposite muscle groups during each movement, building a balanced body in less time. The OYO Gym Pro connects to our OYO App to track and coach in real time while following Nick Bolton's workout videos.
