Powered by GoogleThis 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!
I can’t say enough about this place it is wonderful. Every time my (4year old) son comes in for class the staff is happy to see us and make my kid feel like a million bucks. My son was preemie and has low muscle tone and I think this is a great way for him to work on his overall strength and I am already seeing improvement in his balance and strength after five classes. They come up with new and engaging activities every class it’s really a great experience for kids at any skill/strength level. It’s my son’s favorite thing to do and he looks forward to it every week.
I had my 6 year olds birthday party at this location and I am completely blown away at how awesome it was! We had never been here before so I had no clue what to expect but this place is hands down the best. I will start with the fact that I am a procrastinator so booking a party a couple weeks out was accommodated, then it was considerably cheaper than anywhere else. We had the floor to ourselves, so you aren't trying to party with the general public. The host we had was absolutely incredible. Alex, thank you so much for your patience and your energetic party spirit! He was racing with the kids and getting them pumped up. This was a night and day difference than the host and party we had at Urban Air for a much more affordable price. Also the kids get a free pass to come back! Thank you so much Alex and staff, I can't thank you enough for a great experience. I will absolutely be back
I’m writing a detailed review for parents interested in Lil Ninjas: I took my 3 y/o son for a trial class on a Sunday. The building opens at 9am and class was scheduled to start at 9, which confused me a little. We arrived at 9:04 and class was already in full swing (no pun intended! so make sure you’re early/on time). We didn’t get much instruction, just a wrist band and told to join the group (possibly because we were late?). Initially we were placed with “big kids” (4/5 year olds) so my kiddo was overwhelmed and shy- and so was Mom. The teacher picked up on that and was very patient with him and gave him extra attention. He also allowed me to stay nearby. We eventually joined the group of smaller kids which was a much better fit. I’m giving 5 stars because I was impressed and pleased with the teachers. While young, they were great with the kiddos; patient, attentive, and kept them focused. My son has participated in other activities where the young teachers weren’t as great. The activities and equipment were age appropriate and clean. Balance beams, soft crash mats, a climbing ramp thing, climbing wall and ropes. The teachers taught my son to hold his arms out “like an airplane” to help balance so they actually do instruct. They took water breaks, stretched, and did a ninja hands in cheer at the end. So while an individual sport, it had a team feel. The place appeared clean and didn’t have that “gym” smell. I also appreciated that there was no pressure to sign up for classes.
