See Inside the Swanky Gym Where George Soros Works Out (Plus Soros in Gym Shorts!)

You wouldn’t expect someone like billionaire philanthropist and currency speculator George Soros to work out just anywhere, would you?

Of course not! That's why he -- along with several other business heavyweights -- is a member Sitaras Fitness, an exclusive downtown Manhattan gym.

“Mr. Soros, the billionaire investor and philanthropist, was never one to have time for — or interest in — gyms,” writes Janet Morrisey of The New York Times, “But he was so impressed with the results that his son Alex, 26, got from Mr. Sitaras that he joined two years ago and now works out regularly.”

“My son benefited greatly — he lost a lot of weight,” Mr. Soros says. And despite being 81-years old, Soros actually works out about twice a week.

"It makes me feel better, more alert,” Soros says. In fact, he was so impressed with his experience that he referred friends Paul Volcker, the former Federal Reserve chairman, and Sandra Navidi, founder and chief executive of the financial consulting firm BeyondGlobal.

Sitaras Fitness doesn’t charge an initiation fee, according to its website, but members must participate in at least two personal training sessions a week for $115 apiece and monthly fees run at $150 meaning total annual fees start at $13,760, according to Business Insider.

And as mentioned above, it’s not just Soros who call Sitaras his personal gym; there are several big names working out there:

• Charlie Rose:  "My appreciation of John Sitaras comes from hours and hours and hours of one on one training with him...He has changed my physical health and my appreciation of fitness and how to achieve it..."

• Harvey Fuchs (Citigroup):  "The quality of my life has completely changed for the better by being a member of Sitaras Fitness for the past two years."

• Keith Rubenstein (Somerset Partners):  "Training at Sitaras Fitness has been a rewarding experience in all respects."

• Leonard Harlan (Castle Harlan): "The Sitaras fitness center is like none other in the world."

Oh, and in case you were interested in joining, the gym has 56 spots left…but you’ll probably need a reference from someone like Volker or Soros.
