The Gymboree franchise effort was a triumph. By 1984, 125 Gymboree franchises were operating in 20 states and were bringing in more than $1 million in revenue annually. The franchises were typically operated by women, many of whom had training in occupational therapy or education. Classes were usually held in church halls and community buildings, and parents were charged only $4 to $8 per 45-minute session. Classes varied to accommodate children ranging from three months to four years in age, but a typical session included the children hanging from bars to build up arm muscles, popping soap bubbles to develop eye-hand coordination, or walking on inflated logs to improve balance. In addition, the tots could exercise on brightly colored tunnels, slides, and other apparatus, and no class was complete without a visit from a clown-puppet named "Gymbo."
