If you are looking for a total body portable gym that is ready when you are, the DoubleFlex is an ideal solution. SpiraFlex resistance technology was developed for NASA and is proven to be as effective as free-weights. Just snap on 5 lb. rated FlexPacks to adjust the smooth quiet resistance, which minimizes stress on your joints (due to the absence of momentum of weights). Patented DoubleFlex action activates both sides of muscle groups during each movement, reducing required workout time. Workouts range from 5 to 20 minutes (see DVD).
New for 2017: Upgraded DoubleFlex with strengthen components for increased durability and lifecycle, with 2 year warranty.
Fitness On The Go: Your own portable gym. Lightweight, compact and easy to transport, allowing you to train at home, the office or on the go.
Replaces Weights: DoubleFlex replaces weights with smooth safe SpiraFlex; resistance used by NASA astronauts on International Space Station.
Adjustable Resistance: No need to purchase individual sized weights. Snap on FlexPacks for 5, 10 and 15 lbs. of resistance that feels like free-weights; yet unit weighs less than 2 lbs.
Sculpts and Tones: Patented DoubleFlex movement sculpts both sides of muscle groups and builds a balanced body in less time.
Durability and Long Lasting: Engineered with lightweight / high strength polymers for durability and long life. Cables are nylon coated stainless steel.
