Without exercise, children will never build the strength to cut their own sandwich crusts or tear geometry books in half with their bare hands. Foster childhood vigor with this Groupon.

Choose Between Two Options

• $34 for a one-month membership for one child, including the $35 initiation fee (a $93 value)
$139 for a two-hour birthday party for up to 20 children (up to a $285 value)

Gymboree hosts a calendar of classes specially designed for children from infants to 5-year-olds. Gymboree Play & Learn classes challenge growing minds with fun problem-solving games, and multimedia art and music lessons nurture creativity as parents play along. Members also receive shopping discounts at Gymboree clothing stores, Janie and Jack, and Crazy 8; free open-gym times; and parent handouts.

The birthday party is valid for Friday, Saturday, or Sunday events for up to 20 children and unlimited adults. Children celebrating their birthday can be 5 or younger, but the party is open to children of all ages. Celebrants can choose from a variety of themes, including Little Super Heroes and Jungle Safari. The two-hour festivities include all the trappings and a special gift for the birthday boy or girl.

Gymboree Play & Music

In 1976, busy California mother Joan Barnes wanted nothing more than to find a play place where she and her kids could enjoy age-appropriate, educational activities. Finding none, she developed her own innovative play environment within a developmental-based program structure now known as Gymboree Play & Music. Today, kids tumble and learn in more than 650 locations in 33 countries around the world, engaging in open play and classes designed to build cognitive and motor skills. As parents participate in their child’s development, their kids learn to paint, play music, and interact socially outside of their preschool knitting circles.

Though Gymboree Play & Music sometimes features a discounted price online, this Groupon still offers the best deal available.
