Summer Camps

Looking for something AMAZING to offer your kids over break? Send them to Ultimate Ninjas Camps, where they will learn how to tackle obstacles as seen in the hit TV show American Ninja Warrior. At Ultimate Ninjas it's 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! The camps are designed by 3 time American Ninja Warrior Jesse Labreck, 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 camp, kids are grouped together by 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!


$45 for your first session, each additional session for that week is $40 | 50% sibling discount

Meet our General ManagerJesse Labreck

Jesse was a rookie sensation and has kept up the success on American Ninja Warrior. She broke the record of the first rookie female to qualify for the Las Vegas Finals and has continued to qualify for Las Vegas for all 3 seasons. This solidified her nickname, “Flex Labreck.” Her tenacity and love of the sport has inspired ninjas of all ages! Jesse attended the University of Maine where she got her degree in Elementary Education and developed her athletic skills on the field becoming a track star. Jesse is General Manager of Course Operations at our Naperville location, where she oversees safety, class curriculum and development, camps, events and more. With her background in Elementary Ed and love for the sport, Ultimate Ninjas will be the perfect place for Jesse to teach future American Ninja Warriors via obstacle course racing, or OCR! She has competed on and WON Ninja vs Ninja as the only female Captain of “Labreckfast Club”. She has also competed on All Stars and Skill and USA vs The World where she was the second woman to complete Stage 2!

Jesse resides in Naperville and is also an avid rock climber and hiker. She is an advocate for cerebral palsy awareness through her relationship with a 20 year old woman, whom she cared for while living in Massachusetts.

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.
