The Sansones have a family gym that would earn them a high-five from a professional athletics team. An atypical grandmother of 38, Mary Anne Sansone came up with the idea of a family gymnasium, and her fitness-obsessed husband, Anthony Sansone, was quick to agree. So the couple built a two-story gym addition onto their home in Huntleigh, Mo., seven years ago. The gym is so fully equipped that a family friend who was once crowned the strongest man in the world comes over to work out.
