SpiralFlex technology has kept NASA astronauts for years. And now, that same technology is available from the Oyo Nova Gym. The heavy-duty, high resistance gym is completely portable and gives you total body strength training no matter where you are. Up to 40 pounds of resistance has been added to the original tech for a variety of workouts, and accessories can be added to provide even more at-home workout options. The perfect way to replace those bulky workout weights and machines from your home, the Oyo Nova is incredibly lightweight as well and folds up for travel.
