Take a look at the intense invitation only fitness program run by a Wall Street chief

Welcome to The Program, an invitation only fitness regime organized by the founder of private equity firm Zelnick Media Capital, Strauss Zelnick.

The Program mixes up fitness sessions, from yoga to biking, running, and bootcamp style classes, according to its website. It has a mailing list of about 80 people and now includes women as well as men, mostly in the financial services industry. 

Jason Kelly at Bloomberg just published a fun article about Zelnick and the fitness program. Zelnick keeps the median age in The Program at 28, to maintain a younger and more aggressive mindset, according to Kelly. 

The intense workout routine makes him think like a 25-year-old, Zelnick told Kelly. 

"It drives my investment philosophy," he said.  

You can consider as another example of Wall Streeters taking fitness very seriously. Earlier this year I wrote about the Decathlon, an intense competition that sees traders, fund managers and bankers train relentlessly to be crowned "Wall Street's Best Athlete."
