Nick Bolton will be on QVC the end of this month showing off the Doubleflex powered by SpiraFLEX technology.
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.
