Children are far more delicate than adults, since they lack our fireproof skin and utter fearlessness of a giant gorilla perched on top of the Empire State Building. Let children flourish on gentle grounds with today's Groupon: for $40, you get one month of classes plus a lifetime membership valid for all children in the same family at My Gym of Chino Hills (a $143 value).

My Gym, which currently has more than 200 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 seven months) and designed to incorporate the latest physiological, psychological, and meteorological research. The Chino Hills location offers one-hour programs for all developmental degrees, from Tiny Tykes, a class for parents and babies that focuses on movement, to Champions, for six- to eight-year-olds to master sports and gymnastics skills. Tadpoles aged seven to 13 years learn to be fitness frogs in the Cardio Kids class, which works specific bits of brawn through a four-station circuit training course; instructors also stress the importance of nutrition and frown on the consumption of swamp insects.

My Gym's energetic instructors are experts at using music, dance, and gymnastics to build youngsters' strength and self-esteem, and stimulating their giggle-plexes. The atmosphere is always friendly and inviting, so it fosters creativity and face-to-face engagement in the face of technological temptations and giant robotic faces.
