We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
A serious marathoner friend recently told me that she had leased one of these to train for the Boston Marathon (on Monday). She does 2/3 of her running on the road, and 1/3 on the G.
60 miles/week, plus pool running and swimming a mile every other day. Yes, she is slim and ripped, but prone to shin splints over 40-50 miles/week on the road. She tends to come in right behind "the elites," as runners term them.
She complains that her job interferes with her training. Luckily, her husband and 3 kids are jocks and thus good supporters.
The G was designed as a rehab machine. It's about effort without injury. Review of the anti-gravity treadmill here.
Pool running is cheaper. These things cost $75,000.
I did this for half-an-hour in the Dead Sea. Bobbing like a cork. easy on the knees. A bit irritating afterwards in the private areas; a touch of Vaseline would have helped.
Cheaper than $75K for this machine, even with the air travel.
