The instructors at Wright's FUNdamentals, an offshoot of Wright's Gymnastics Academy, strive to build enthusiasm for gymnastics, dance, and fitness among kids younger than 9 years old at their two Greenwood facilities. Here, tykes plunge down slides into ball pits, tumble on cushy mats, and swing from monkey bars and rings during open-gym sessions, which foster free-form frolicking throughout the indoor playscape.

For more structured bouts of energy expenditure, kids as young as 2 can hone their coordination, fitness, and summersaulting aptitude in a host of age-appropriate gymnastics and cheerleading classes. The Ninja Gym classes challenge boys to conquer military-style obstacle courses, using ninja-style moves to fend off any rogue cooties from the girls.
