KinderKidz is our preschool gymnastic program for ages 6 months to 6 year olds. Our knowledge of gymnastics and brain development has inspired us to focus our Kinderkidz Program around critical milestones for proper brain development through movement. In this program your little one will develop motor skills, basic muscle coordination, and as well as create lasting friendships.
Giant Gymnastics strives to ensure all kids are placed in the correct class. The tables below are a guide in helping you find a class that best suits your child's ability and age. Still unsure? We offer 15 minute evaluations or a trial class at no cost. Please call the front desk and our friendly office staff will be happy to assist you.

My son has been attending this gym for the past six months and loves each session. I also joined a mommy and me class T the same time with my daughter and it's the highlight of her week! The instructors-patty and Jamie-are the perfect mix of kind and challenging. Learning life skills like waiting our turn and using manners are just as emphasized as learning gymnastics skills. My son has learned so many skills like rolling backwards, cartwheels, trampoline jumping and balance. I would highly recommend this gym to all.

Had the worst experience with this gym. Sad to say my son was so excited to go. He is only 3 and loves to jump, climb, and do things related to gymnastics. So we sign him up. After a month the coach comes up to my son and asks if our son is going to listen this week and the coaches have a nickname for him. So my wife asks "what is the nickname". Well the coach tells my wife the name. It's not the thing you would say to a 3 year old growing child. Especially in front of him. Wow what a bully coach of a 3 year old. Way to go Giant gymnastics! This place may be good for older children
