Your personal gym that replaces weights for fitness at home, office, or on the go. Powered by our patented SpiraFlex resistance technology used to keep NASA astronauts in shape on the International Space Station, the OYO DoubleFlex Personal Gym is the world’s only exercise device that applies resistance to both sides of muscle groups in one motion, building a balanced body in less time. Build lean muscle without the use of free weights and resistance bands. Weights have safety issues, including straining, losing balance, and joint stress from stopping and starting momentum. Weights also have portability issues. Resistance bands only produce progressive resistance (like rubber bands), so the muscle is not fully activated until full extension. With our SpiraFlex technology, you get smooth constant resistance while avoiding the safety or portability issues of weights.
