GymAbout the Club
Ninja Republic is the only gym on the Peninsula that is 100% dedicated to ninja warrior. Classes, competitions, camps and birthday parties... all ninja! Drop in for an open gym session, sign up for a class or book a party that will leave your guests calling it the "best party ever!" Seriously, we hear those words at least a dozen times every weekend.
Please check our homepage for our schedule as it changes week to week. Weekends are typically booked with birthday parties and they have exclusive use of the gym, so check before you drop in.

This place is AMAZING!! It’s clean and well run, with very friendly staff. My kids go there a lot for thier camps, and always come back happy and tired with tales of new ninja moves. The owner is a great guy who really enjoys helping kids connect with their bodies in a fun way. Definitely worth a visit!!

One of the first kids birthday venues in the area that I, as a dad, had fun at. They don't check what's in your cooler and they let you try the real ninja warrior walls. Oh, and the kids had a blast. Highly recommended.

We hosted my son’s birthday party at Ninja Republic. We had three party attendants who made sure everything went well. They kept the party on track and did everything from helping set up food, get the kids through the obstacle course, serving food and cake, to clean up. They also showed the adults how to properly use the equipment (salmon ladder, 8 foot wall, etc.) I would definitely recommend for a kid party!

We went there around 3 p.m. after the summer camp kids had mostly left. It was not crowded at all, and my 8-year-old daughter and her friend had so much fun. There was one employee named Liam who made it even more enjoyable for the kids. Half of the facility was challenging enough for 8 and 9 year-olds, while the rest was more advanced. We will definitely come back again!

My 9 year old has been obsessed with American Ninja warrior for a while now, and we have been going to Ninja Republic since December 2023. He said it was his favorite part of Winter Break.
Since then, we’ve been regulars at their Sunday morning open gym, hosted his birthday, and had two weeks of summer camp at Ninja republic.
This is not some chain place run by a bunch of high school kids like those trampoline parks. Sure, your kids run a lot and burn off a lot of energy, but that’s about where the similarities end.
The owner, Regan obviously cares about safety, cleanliness, and encouraging kids to push so they can get better (at an appropriate level). He knows all the regulars. He does have very young staff but they are all super sweet, helpful, and encouraging.
We love Ninja Republic :)

It looked a bit small when we walked in but definitely kept the kids entertained for 2 hours during open gym. Owner is super nice. There are plenty of tables to take breaks.

Great course for kids and adults. I was expecting it to be basically a kids place (and it was great for that especially since for parties you rent out the whole space) but there are tons of great obstacles that will challenge almost any adult. The staff were super friendly, great with kids, and had a lot of good tips, both for kids and adults, on how to do the obstacles.

Went here for a bday party for my daughter’s friend. They had so much fun. The obstacle course is for all ages from adult to kids. There’s plenty of seating for parents while their kids play.

If I can give 10 stars. I would. The owner is amazing, and he definitely knows how to take care of his customers. He really is involved and interested in just challenging the kids and understandingwhat their doing. This place was amazing. My kids had a 3 hrs of so much fun and didn't want to leave. And their looking forward to coming back for sure. Definitely recommend bringing your kids. I have a 4 year old and a 6 year old. I was skeptical that it was gonna be too challenging for my 4 year old, but he was able to keep up with the bigger kids of ages 5 and 6 years old. He got all the kids together to learn techniques and challenge their skills. Which made it more engaging for my kids and definitely so much more fun than by themselves trying to figure it out. They really had a lot of fun.

We went to open gym today at Ninja Republic and my kids had so much fun! There are a lot of different obstacles for them to try. There are sections set up for younger kids (I would say from about age 5-7 or so), and then more for older kids and adults. It was clean, the staff was friendly and helpful, and I would say it was reasonably priced compared to other open gym/ninja warrior courses in the area. I highly recommend it!

My daughters, ages 7 and 9, had an amazing time at Ninja Republic on Saturday—so much so that they convinced us to return the next day and the day after that! Regan is an excellent coach. He set up each kid with customized challenges and offered pointers on how to succeed. Most importantly, Regan and everyone at Ninja Republic is very encouraging, kind, and community-oriented. We can't wait to return again!

After watching Ninja Warrior on TV for so many years, my kids finally got a chance to try it out in real life - and they loved it! Big props to the owner, Regan, for bringing a ninja gym to the Peninsula and for making so many kids (and their parents) super happy!!! 🤘

We stopped by for open gym over Memorial Day weekend. The kids had a great time trying the obstacles, especially the small warped wall and cargo nets. The owner was super encouraging and was giving kids tips on how to do the obstacles. My daughters and their friends had an awesome time (ages 12-8).

Check out this new studio on the peninsula! My daughter went there for a birthday party and had an absolute blast! It's so nice to have a fun place like this near Burlingame/San Mateo, and the owner is really fantastic.

This was the perfect venue for my 10 year old daughter's birthday party. The kids LOVED the challenging obstacles - especially the warped wall. There was plenty to explore and keep them all entertained...so much so that it was hard to get everyone to leave :) Parents will love the ease of this space with the party room for food and cake. Kids will love bouncing off the walls, jumping, and swinging from a variety of obstacles. We are so excited to have this space in San Mateo. My daughter already wants to book it for her next bday!
