OYO Fitness ® is launching the DoubleFlex ®, a total body portable gym, powered by SpiraFlex ® technology developed for NASA, which has been proven to provide similar benefits to weight training – without weights. SpiraFlex enables the DoubleFlex gym to be lightweight and portable, yet provide total body fitness at home, office or traveling. Patented DoubleFlex action provides smooth consistent resistance to opposing muscles groups during each DoubleFlex movement, helping build a balanced body more efficiently.
