Michael Fertik is an American Internet entrepreneur, who currently works as the CEO of Reputation.com, a technology company that focuses on matters of online reputation management and Internet privacy. He always wears a weight vest to keep him fit.

He says, "Like my standup desk, the weight vest is something I do to maintain fitness. It’s easy for busy professionals (including me) to say they can’t make enough time for exercise – but wearing the weight vest has been a simple way to passively incorporate some extra challenge in my day. And it does get heavy!"
