During long flights, it is impossible to get much exercise. For some people, this can cause swelling and/or pain in the legs and ankles. There is also some risk of forming blood clots in the legs (thrombosis), which this simple product easily helps prevent.
Invented by an airline pilot, Airogym is simply an inflatable, heavy duty sack which is narrow in the middle. When it is partially inflated, it is possible to transfer the air from one chamber to the other by alternating pressure with your feet. Airogym's website demonstrates that this results in increasing blood flow in the legs by up to 300 percent!
I purchased mine because we are flying to Hawaii in a couple of weeks and I have a tendency to ankle swelling. When I received it, I tried it right away and find that it helps me with the swelling problem while sitting at my computer as well.
The company was pleasant to deal with, and shipping was super fast. I see Airogym as an innovative and helpful product.
