It was 1996. The Macarena was in full swing. Prince Charles and Princess Diana finalized their divorce. Mission Impossible with Tom Cruise debuted in theaters worldwide. And Reebok STEP was in full fitness force. I know because I was an instructor. And when I first moved to New York, I mailed a letter to this fantastic British woman I’d seen in the STEP videos. Her name was Petra Kolber. I wanted to see if—by some crazy chance—she’d be willing to have coffee with little ol’ Ali Brown, as I was considering teaching classes in the city.
