Kids Sessions (Ages 5-12)
Kid Services
Kids Classes Book Now

Our instructor-led sessions incorporate different obstacles based on the ages of the participants. We design the class to develop core, agility, balance, strength and overall confidence in each child so they can conquer obstacles both in and out of the gym.

All of the movements can translate to other sports and activities. But, the most important thing is they are having fun by jumping/swinging/running/bounding over, under and through obstacles!

Kids Open Gym Book Now

This session is for kids that want a little more freedom to pick what stations they want to try.
This is not a "free for all". The coaches will create 2 or 3 stations at a time and each child can pick which one they want to do. If they want to run up the warped wall for the whole session, they can! If they rather rotate between all of the sessions, they can!
