Dropped in as a guest for a Friday night lights workout and had a great time. They gave me some pointers on lifting technique and everyone was friendly. Fun gym!

5-Star Fitness Haven – Everyone's Home Away From Home! I've been a member at Tundra for two and a half incredible years now and it's honestly one of the best decisions I've ever made. This is not just a gym, it's a community! A judgement-free space where everyone is welcomed, motivating, and encouraged, no matter your fitness level or background. From day one, the trainers and members collectively cultivate an atmosphere that screams 'inclusivity'. Here, it doesn’t matter if you can lift 20 lbs or 200 lbs, regardless of who you are, you're met with respect and camaraderie. This gym truly embodies the 'No pain, no gain, one for all, all for one' spirit! The trainers are top-notch – not only are they skilled and knowledgeable in fitness, they have a fantastic knack for understanding your capabilities and supporting you along your fitness journey. They’ll push you without breaking you, encourage you when you think you can’t do anymore, and celebrate every single one of your achievements with you! The programming is varied, challenging, yet surprisingly fun! And the members, oh the members, they're just the icing on the Tundra cake! Everyone respects each other’s space but are always ready to lend a helping hand or a pat on the back. The infectious positive vibe and the sense of brotherhood/sisterhood here is just unmatched! Summing it up, Tundra feels like playing a team sport. It's challenging yet rewarding, and full of adrenaline and exhilaration. If you want to experience fitness in an environment that embraces diversity, fosters friendships, and values team spirit, then look no further. This community is ready to welcome you with open arms and plenty of high-fives. My only regret? Not joining sooner!

Went for friends and family day, had the best time ever, I highly recommend if you want to get a great workout with friendly people who tell you step by step what to do, me as a person who does not work out was totally lost so I felt really comfortable, I hope to go back one day!!

I am having an absolutely great experience. I moved to grand forks a month ago and joined this facility. CrossFit tundra is not only a great facility for your workouts but filled with wonderful friendly people. Thanks a lot!

The people here know what they are doing. And extremely caring and helpful. Unlike a lot of places they are patient and willing to go the extra mile to make sure you are doing things correctly and that you are comfortable there
