Exercise leads occasionally to injury, and for treating the busted knees, there’s probably no one better than Leach. He works with the Boston Celtics, the US ski team, the Olympic squad, and top professional tennis players. “The real action though,” Leach says, “is not with the pros. It’s with the people who are doing sports for fun.” That category includes Leach. With son Mike, the Leaches are a nationally ranked tennis duo.

They recognize I’m relating.”
