This is the best and pretty much the only gym in the area to train at if you are looking for a ninja warrior type experience. The place is small and in its infancy, but they have large aspirations and are adding new obstacles weekly. David (the person who runs the gym) is great and has been building obstacles upon request for ninjas preparing for the upcoming American Ninja competition in a couple weeks. They have the essentials here. A warped wall, a salmon ladder and a lot of hanging grips to work on. I also bring my son here during kids classes and he has a blast. The adult open gym is affordable and what I normally go to. The kids classes are pricey IMO though and you have to commit to a tuition with an initial fee. They follow the same model as the attached gymnastics gym (which owns Sumner Ninja). A drop in kids rate would be nice. Looking forward to training here a lot more!!!

What a fantastic, A+ experience! I booked an adult ninja birthday party for my husband and 9 of our…read morefriends. David was such a fantastic instructor/guide. He gave us tips on how to succeed on the obstacles and encouraged us to try everything. The gym itself had all the remnants of American Ninja Warrior (scaled down of course). We booked it for 90 minutes, but David let us stay over a few minutes to flip the tire and try a few more obstacles. I highly recommend this place if you're looking for an awesome group activity or if you're a fan of the show. If you're booking a party, I would recommend keeping the group small (maybe no more than 15) so everybody has a chance to do the obstacles multiple times. With the ten of us, we never felt like we were waiting around too much and got adequate rush between each obstacle.

we LOVE this place. very retro & old school down to the tin cash box. incredible pricing options,…read moreplenty of gym space & activities for all levels! we particularly adore the 'open gym' option as it gives kids a chance to explore freely & focus more on simply having fun 7 not olympic training, which is also offered at metropolitan gymnastics. the coaching staff seem knowledgeable & professional- easily spotted & never not paying attention. overall, i highly recommend MG. hope this isn't petty but the only reason I'm giving this place 4 stars & not 5 is that the ventilation needs updated or the props disinfected more often or something because the stench is overwhelming. i have to fight the urge to bring my own lysol haha. also the vending machines never work so that's always a hassle. trivial but still. (not including a photo as to protect the privacy of any children in them. Definitely a facility worth checking out for yourself!)

Some parents stay, some drop off ( we do a mix of both). It is a treat to stay and watch all the kids have fun and interact. We loved it so much we had our daughter's 4th birthday party there and was able to introduce MY GYM to a bunch of new people who came out for the Party. We're excited to do one of the many camps and parents night out events. Location is great for us, it's only a 10 - 15 min drive. There is a variety of equipment and it's well maintained that I can't help be so happy that we are part of this community. Thank you to the kind and friendly staff!

Review for the Presidents' Day day camp!…read more I grew up in Kent and my parents still live there so I've seen My Gym for years... My son's cousin was registered for the Presidents' Day day camp so we decided to register him, too! It was $49 for a 3 hour drop off session. The camp included games, open play free time use of the space, crafts, and more with other kids and teachers. Upon first look everything looked really clean and safe! My son was a little nervous to be left without me on the sidelines, but when I returned I could tell he formed a comfy relationship with the teachers working and they mentioned how well he did during the duration of the camp. We've never done something like this so I'm glad to have it on my radar for school breaks! They also host "parents night out" events where you're able to drop the kids off and go on a date night - which is a really fun alternative to keeping the kids at home with a sitter. Worth noting that kiddos need to be potty trained and able to separate from parents in order to attend the drop off camps. We'll definitely be bringing my son back in the future!

Debbie is lucky that I didn't sue her for the mistreatment of my daughter. For the record, we wasted about three years at this place. I have talked to many people that have gone here before and they also agree it was a waste of time. This is not personal, but this is a warning to not waste your time or money unless you are looking for a poorly run gym that reflects a mismanaged daycare. If you are just looking for something to fill your kids time, go here. If you are committed to progress in a truly physically demanding sport, look outside of Maple Valley. I hope that a more professional gym buys this place out so that we can have a real gymnastics place in Maple Valley.
