What is Mini Heroes?

Ninja Class for Kids Aged 3-5

Most of our offerings are for ages five and up. This is for safety. With open gym during all of our regular hours, we can't have kids under five on the floor, even in a class. But your three and four year olds love Ninja Warrior too. That's what Mini Heroes is for!

Mini heroes is our class for kids aged 3-5. It takes place outside of our most popular open gym hours, so we can safely have younger kids on the floor!

Mini heroes is a fun fitness class that will give kids a taste of ninja, get them on some obstacles, teach them basic ninja skills, and play games with ninja elements!


Class will start with a brief warmup, and get quickly into the fun! Our coaches set up courses at the right level for three-to five year olds. This is another great benefit of holding mini-heroes outside of open gym hours! We also modify some of our obstacles to make them easier for our mini-ninjas to try. The warped wall is always a big hit, and we can lower the height with a rope to give the perfect level of challenge! Mini ninjas often try our racecourses, and practice ninja skills like swinging on rings and monkey bars. Class ends with games using our ninja obstacles, like airbag tags and the floor is lava.


This class is a great way to introduce younger kids to ninja. We're so glad to be able to offer a class to three and four year olds!

Saturday, June 30, 2018 - We held the Grand Opening of our first Ninja Nation location in Lafayette, CO.   We were overjoyed and overwhelmed with the 2500 people who showed up to celebrate with us. The opening featured a Ninja Showcase with Ninja Nation's own Geoff Britten, Brian Arnold, Jamie Rahn, Ryan Stratis, and Rian McLean as well as guest Ninjas Rachael Goldstein, Adam Rayl, Austin Grey, and Barclay Stockett. We even had surprise appearances by Rocky the Denver Nuggets mascot and Chip the Buffalo from the University of Colorado in Boulder.   We had a blast and we hope you did too.
