Bringing Ninja Gyms to new places

Building Twentyone

World Ninja Sport is excited to announce the completion of a new Ninja Gym at Building Twentyone in Holt, Michigan. The gym is a state-of-the-art facility that offers a variety of ninja warrior obstacles and training courses for people of all ages and skill levels.


Building Twentyone will positively influence students and continue to guide them in pursing their passions by providing unique and diverse opportunities through the pursuit of sponsorships, community support, and dollars raised in an effort to expand and better the center, its programs, and the safe environment for students to find their place.


Building Twentyone Philosophy:

It takes just 21 days to form a habit, and the most influential habits are formed before the age 21. Building Twentyone is a unique, youth-driven center focused on building trust, hope, character, influence, and potential in students before the age of 21.


The gym is also a great place for people to have fun and socialize. The obstacles are designed to be challenging and fun, and the training courses are a great way to test your skills and compete with others.

Here's a behind the scenes look at how the build came together and the finished product :-)
