Grand Opening of the X-Treme Ninja Course 3: A New Era of Outdoor Fitness in Ontario, California

Greenfields Outdoor Fitness is thrilled to announce the successful grand opening of our latest and most exhilarating project yet – the X-Treme Ninja Course 3 in the heart of John Galvin Park, Ontario, California.


Great for teens who have aged out of the playground, this state-of-the-art fitness installation marks a significant milestone in our mission to revolutionize outdoor fitness landscapes across the nation. Also, the course includes all-new features and is the first X-Treme Ninja Course 3 Greenfields has done!

An X-Treme Day to Remember

The community of Ontario braved the rain because of the excitement to see their newest outdoor experience. The grand opening of the X-Treme Ninja Course was not just an event; it was also a celebration of community, strength, and the boundless possibilities of outdoor fitness. Six-time American Ninja Warrior finalist and National Ninja League 2019 World Champion Adam Rayl joined the festivities, consequently bringing energy and enthusiasm to the launch of our latest project. Additionally, service members in the United States Marine Corps were in attendance and showed everyone just how tough our military is by taking on the Ninja Course. There were even a group of young ninjas who got to preview the course, showcasing their agility and physical prowess along various portions, so as to impress their parents and onlookers. As a result, the air buzzed with energy as attendees were cheered on by friends and fitness enthusiasts.

More Than Just a Fitness Course

At Greenfields Outdoor Fitness, we believe that fitness should be fun, accessible, and integrated into the natural beauty of the outdoors. Accordingly, the X-Treme Ninja Course embodies this philosophy to its core. The course provides a dynamic and adaptable workout that promotes strength, agility, and perseverance. Because of this versatility, the course caters to a wide range of fitness levels.

With John Galvin Park, X-Treme Ninja Course 3 is our first of its kind available for public use. As such, new features exclusive to this course — some of which are modeled after ninja courses seen on television — are now ready to be challenged. Those features include:

  • Rock Wall
  • Crankshaft
  • Hanging Beams
  • Tire Swings
  • Hanging Coins
  • Double Loop Jump – A favorite among the attendees
  • Swinging Ropes
  • Hanging Platforms
  • Vertigo 5 Trainer

A Partnership for the Community

The realization of this project could not have been possible without the unwavering support of the City of Ontario. This collaboration proves what communities and corporations can achieve when they work hand in hand towards a common goal. Redefining public health and making fun, engaging spaces for physical improvement is easily accomplished because of this partnership.

Looking Forward

The opening of the X-Treme Ninja Course is just the beginning. We’ll keep creating innovative outdoor fitness solutions for communities nationwide. In the meantime, join us at John Galvin Park to try the X-Treme Ninja Course for a healthier future. Your enthusiasm and support inspire us to keep pushing the boundaries of what outdoor fitness can be. Here’s to many more milestones ahead!
