FITNESS CLASSES
Ten-year-old Blair Danahey takes fitness seriously and loves it. Blair, the daughter of Jacquie and Kevin Danahey, members of Knollwood Country Club in Granger, Indiana, is toning up in the club’s new triathlon training program for kids. Three or four days a week, she and other fitness lovers work with the club’s swim coach, then those tall enough to use the stationary bikes do some sweat-inducing cycling. All the kids get cardio training in the aerobics room and upper-body workouts in the weight room. Knollwood will hold its first triathlon for kids in August, and Blair plans to go for gold.

In fitness classes at Haile Plantation Golf & Country Club in Gainesville, Florida, kids get moving in Zumba classes — high-octane workouts to upbeat music from around the world. Besides folk dances, they learn the latest steps from countries like Kenya, Russia, and tango’s birthplace, Argentina.

Brookhaven Country Club near Dallas offers kids everything from ballet classes and basic motor-skills training for various sports to aerobically fashioned relay tag races. During the club’s summer camps, kids learn tumbling and martial arts, including kickboxing in the pool.
