My Gym Children's Fitness Centre

My Gym Chatswood transforms a private studio in the Mandarin Centre into a gymnastics playground packed with bars, beams, trampolines and a crowd-favourite Space-Flight zip-line. Two certified coaches guide high-energy games, songs and age-tailored circuits while parents watch from comfy sidelines.

Packages start at $618 for the Grand Celebration (up to 10 children) and step up through Deluxe ($758, 15 children) to the Premiere at $999 for 20 guests. Every tier grants 90 minutes of exclusive gym time, customised activities, themed goody bags, invitations, a special My Gym gift and full set-up and clean-up; Deluxe adds balloons and Premiere also includes a juice box for each child. Families supply their own food and cake (or arrange catering through the gym), and parties can be extended to two hours or staffed with an extra coach for an additional fee. A non-refundable $200 deposit locks in the date, and themes from superheroes to princesses are included at no extra cost.
