Looking for something AMAZING to offer your kids over break? Send them to Ultimate Ninjas' Winter Kids' Camp, where they will learn how to tackle obstacles as seen in the hit TV show Ultimate Ninja Warrior. They have never had so much fun learning how to challenge themselves. Here, it is so much fun to get back up and try again.....

At Ultimate Ninjas, we instill self-confidence, acceptance, and a true hunger for tackling obstacles with a positive mindset. The best part: we have a BLAST doing it! Led by 3 time American Ninja Warrior competitor Kirsti Pratt, you will not find a more positive environment where kids can show up, be valued for exactly who they are, and discover what they are uniquely capable of achieving.

During winter camp, kids are grouped together depending on their age and rotate through stations where they are coached on each obstacle. After learning how to tackle the obstacles, they have time for open play so they can pick their favorites and spend extra time on the obstacles they want to master or just enjoy! At the end of camp all kids will get a chance to run through the course with their coaches just like you see on TV!

Registration is up now online! Save your spot!

MeetKirsti Pratt



Kirsti is a 3 time American Ninja Warrior and one time Vegas Finalist. You can also see her on 2 seasons of Ninja VS. Ninja where she remains undefeated even after running against popular ninjas like Jesse Graff.

Kirsti’s passion is to grow the ninja community and promote the ninja lifestyle of being able to play and have fun while staying in shape, eating healthy, treating people kindly, and supporting fellow ninjas.

Kirsti has a Certification as a CHEK Practitioner which helps her bring her fitness knowledge of functional training to her ninja classes. She has been competitive her whole life playing many different sports like soccer, ice hockey, golf and racquetball. When she started competing for American Ninja Warrior at 21 years old she was just coming off of a stress fracture in her low back. When Kirsti first started she had to learn how to scale things to the basics and work her way up from there becoming a strong female competitor now. She cannot wait to teach our Jr Ninjas those same basic skills and life lessons.

What our customershave to say about us


We just threw my daughter’s 6th birthday party here and it was wonderful! They were very helpful and accommodating. Our guests had a great time and the staff assigned to help our party could not have been nicer. I would recommend this for a party venue (or just a fun open play/class activity) to anyone!Hannah B.

I brought my 11YO son today for open gym and he absolutely loved it! It definitely became more crowded after 12:30, but the staff was great and offered assistance when requested. The obstacles were just like the show and are easy to try, but challenging to master. We will be back for sure!Amy J.
