Metro Detroit's Premier Ninja Warrior, Obstacle and Climbing Gym!

Whether you are looking to train for American Ninja Warrior, Ninja Warrior Junior, Spartan Race, Tough Mudder, cross-train or just want a fun exercise alternative, we are the gym for you!

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

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

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!

Ninja Team

Our comp team practices and competes in competititions around the country. Our coaches make a best effort to provide coaching at each of the local competitions, but it is provided voluntarily by our staff.

Do I need to tryout for the team?

Yes, we will be holding tryouts on Oct. 1 for ages 11+ and Oct. 4 for ages 6-10. We will not be cutting anyone based on tryouts, but they will give the coaches a chance to evaluate each athlete.

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 National Ninja League (NNL), the largest ninja league in the world. We will focus on NNL competitions but encourage our team to compete in other leagues. The closest NNL 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 NNL competition in our region. The team membership does not include travel/time for coaching, so all of the coaches volunteer their time and expense during competitions to help out the team. We intentionally kept the team membership cost low to encourage more involvement in the sport of ninja.

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!
