A new device called the OYO Personal Gym, using NASA spinoff technology, recently came to market. At first, I thought it was going to be another one of these fitness gimmicks. The OYO gym touts itself as a full body touts itself as a full body portable gym, featuring SpiraFlex resistance technology — the same technology NASA astronauts use — that replaces weights.
What is the OYO Personal Gym?
The OYO Gym is a total body gym that weighs 2 lbs but produces up to 25 lbs of free-weight (isotonic) type resistance. Patented SpiraFlex resistance feels like the cable machines at the gym, yet does not use gravity. It can be folded to fit in your bag, so you can use it at home, office or on the go — wherever you can fit a workout in. The OYO Gym comes with one 5 lb and two 10 lb rated FlexPacks, as well as leg and door anchors, an exercise wall chart, and nutrition guide.
A 16-week NASA study 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 can have safety issues, including losing balance, and joint stress from the stopping and starting momentum. Resistance bands produce progressive resistance (like rubber bands), thus the muscle is not fully activated until full extension. SpiraFlex creates smooth linear isotonic resistance like free-weights – without the weight.
