It's really intimidating walking into a new gym (especially when you have never done martial arts before), but everyone at Darkside is so welcoming. All the trainers are super nice and take an interest in you -- no matter what stage you’re at. I like how they give me tips so, that I get the most out of every class. I've learned a lot the past couple of months and not to mention, I'm having fun while doing so! Glad I made it out and joined the club. Would highly recommend 😁

Great place to learn a new skill and be physically active. Three demo classes, staff was helpful, and explains techniques for moving forward.

A great atmosphere to train. Signed up for a year and they kept me positive and ran virtual training during the pandemic. Can’t wait to get back to it. Can’t recommend the place high enough.

I have been training here since July 2020 and it has been a great experience. All the coaches/trainers at this gym are very welcoming and knowledgeable. Like any other gym, the harder you work the more you will get out of your experience but Darkside is still a great place to train recreationally as well! I would recommend anybody interested in martial arts to come train.
