    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 seenon TV. 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 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!

    By far the best sport I have ever put my kids in. They have learned so much from these classes. They are in little ninjas and have a blast every week.

    This place is great for anyone interested in the ninja sport. Our family started as beginners here and after years now we have found a sport and gym that the whole family loves. The staff are ALWAYS great and upbeat and keep up the positive energy whether during practice, open gym, and certainly birthday parties—which are also a blast here and well attended by invitees. I highly recommend this ninja gym.

    What a great place. They’ve thought of everything to create a truly fun, creative, and challenging ninja gym for people of all ages, from toddlers to the more seasoned ninja athletes. The welcoming, nice staff are the best part. They LOVE the kids and do such a great job coaching and making them feel cared. Can’t say enough great things about Ultimate Ninjas Chesterfield. Thank you for being such a great place for my son!

    The owner is engaged and awesome, just recently attended a homeschool kids event and she had a really well put together marketing table, held a raffle, and the kids had a blast! Great place to wear out your kids.
    I love this place and so do ALL 4 of my kids. Management is good, classes are great and the set up changes often. It is a great place for functional strength and fun!
    We visited with the kids for a birthday party. They love it!! The facility is clean and well maintained. The staff gave very clear instructions to all of the kids and watched over them during the entire party. They were very professional and made sure all the kids had fun.

    Love this place. Lots to do and very cool. Can’t wait to come back for homeschool groups.
    A completely frustrating experience from a competition standpoint. Nothing ran on time, obstacle changes were painfully slow, and there was zero consistency throughout the event. We’ve never encountered a competition this disorganized before.

    This place is amazing! Our 4 year old daughter is in Little Ninjas. Idk how the mom coaches do it with all those littles but MAN they do! It takes a special kind of person to do what they do. I am so grateful!

    My child loves coming here and has a great time. Have been attending and don’t plan to cancel or leave. I just wanted to mention(in hopes it will be corrected) there seems to be some blatant favoritism for certain kids by multiple coaches. While I’m glad they have good relationships with some families but sometimes I’ll see my child needing some aid but they are more focused on specific kids. Also I wish they would tell parents not to yell during sessions. Some parents be doing too much. Let the coaches coach.
    my child is not a terror child either… they are very easy going.

    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!

    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!
