My Gym, which currently has more than 270 international locations, began more than 20 years ago as a structured place for children to safely play, acquire new skills, and romp off a sugar buzz. All classes are organized according to age level—starting as young as 6 months—and designed to incorporate the latest physiological and psychological research. Tiny Tykes gets babies moving with help from their parents, Mighty Mites teaches toddlers self-reliance and beginning sports skills, and Whiz, a class for kids aged 4 to 6, emphasizes motor skills such as running, jumping, throwing, and kicking. My Gym's energetic instructors are experts at using music, dance, and gymnastics to build youngsters' strength and self-esteem while stimulating their giggle-plexes. The noncompetitive environment fosters creativity, and hands-on activities boost children's learning retention and fun quotient.
