SpiraFlex was developed for NASA as the Mission Critical resistive exercise technology for astronauts on the International Space Station. SpiraFlex creates smooth linear isotonic resistance like free-weights – without weight.
A 16 week study funded by NASA found both the free-weight and SpiraFlex groups gained similar improvements in strength and muscular hypertrophy, with significant increases in lean muscle mass. Lean muscle is the body’s most efficient fat burner.
Weights have many safety issues, including straining, losing balance, and joint stress from stopping and starting momentum. Weights also have portability issues. Resistance bands produce progressive resistance (like rubber bands), thus the muscle is not fully activated until full extension.
Patented SpiraFlex® technology provides smooth consistent (linear) resistance through the entire range of motion, which is Mission Critical for you to build a lean strong balanced body.
SPIRAFLEX TECHNOLOGY DEVELOPED FOR NASA
OYO Fitness CEO, Paul Francis, invented the SpiraFlex® technology that was used in NASA’s Interim Resistive Exercise Device (iRED), that kept astronauts fit on the International Space Station. Studies have proven the best countermeasure for bone density and muscle mass loss on earth is weight training — but weights don’t work in space. It was mission critical for NASA to find a solution before the first crew arrived.
After two years of intensive development and testing, Francis’ team delivered the first resistive exercise device in space. So far, over 50 crewmembers on the International Space Station have kept in shape using patented SpiraFlex technology.
SpiraFlex technology not only powered NASA’s first strength training device, but also one of the best and highest selling home gyms — the Bowflex Revolution.
