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

The most diverse and updated training equipment and obstacles in Michigan.
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 Classes
Ages 5-12
Our classes 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!

New Policies Effective Immediately

Our new policies have been put in place to vastly minimize the risk spreading the virus.

  • Masks will be required for everyone.  We will be selling some sweet Gripz masks for anyone that doesn't have one.
  • Stay at home if you are sick.  This should be self-explanatory at this point, but if you have had any symptoms in the past 14 days, or have been in contact with anyone having symptoms in the past 14 days, please stay home.  We won't be taking temperature at the door.
  • Limited In-Gym Transactions.  To minimize surface transfer, all transactions should be done online.  You can purchase all of our goods and services online.
  • 50 Minute Sessions.  To limit airborne and contact transfer, all classes and open gym sessions are limited to 50 minutes.  That gives our coaches 10 minutes to clean between sessions.  You can attend up to 3 sessions per day.
  • Max Capacity - 15 Participants. We will be vastly limiting the number of participants in our sessions.  We ask that any non-participants wait in their car, if possible. Otherwise, we will limit 1 guest per participant.
  • Stay 6-Feet Apart. While you are in a session, we ask that everyone maintains social distancing of at least 6 feet.
  • Liquid Chalk Only. No loose chalk
