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!

Do I need to sign up for all 3 sessions?

No. Because kids play other sports, we didn't want to lock them in for the 9-month ninja season. You only need to commit to a single 3-month session.

Can I sign up after a session starts?

Send us an email to info@gripzgym.com and we can look into options.

What does it mean to be on the team?

The ninja team will practice together and motivate each other at competitions.

Where are the competitions?

Gripz is associated with the World Ninja League (WNL), the largest ninja league in the world. We will focus on WNL competitions but encourage our team to compete in other leagues. The closest WNL gyms (other than Gripz) are in Ohio and Canada with new gyms being added every few months.

Will the coaches be at every competition?

We currently have 4 certified coaches that will make their best effort to coach at each WNL competition in our region. The team membership includes one coached competition per month.

What can I expect at a competition?

We have livestreamed many of our competitions that you can view on our YouTube page.

Is team right for me (or my child)?

If you enjoy playing on obstacles and want to see what the competitive side of ninja warrior looks like, then the ninja team is a great fit!
