Junior Gym is a play gym designed for children aged 6 months to 7 years old, focusing on developing gross motor skills such as running, marching, and hopping, as well as improving balance, coordination, muscle strength, and core strength. They offer various classes like "Caterpillar" (caregiver-assisted for 18 months-5 years), "Butterfly" (supervised drop-off for 3-5 years), and "Gym Ninjas" (for 5-7 years), incorporating thematic units and musical activities. Junior Gym also provides "Open Gym" sessions for children up to 6 years old, allowing for free play in their equipped gym, which includes a trampoline, climbing wall, balance beams, and trapeze. Their mission is to create a supportive environment where children of all abilities can grow their self-esteem and confidence. They emphasize learning through circuits of equipment that are set up differently each week and encourage organized musical activities within their 45-minute classes. Additionally, they offer "Gym Babies" for infants and caretakers on a drop-in basis, focusing on exploration and socialization. Reservations are typically required for all activities, and a waiver must be signed by all participants and accompanying adults.
