    I absolutely love this gym! I’ve been a member since December and have taken just over 100 group training classes. They are SO fun, challenging, and my strength/endurance has drastically improved. The trainers are wonderful and bring such a positive vibe to the classes. I love the community feel here and have met so many great people. The front desk staff, owners, and trainers are all a 10/10. Highly recommend!

    I love my gym! Super clean and nice new equipment for a affordable price. The group training classes are great! I was a bit nervous going in alone, and they took me under their wing, and we’re very welcoming. The staff is super helpful and kind.

    I needed a place to workout while visiting Kalispell, and picked Sweat House. A week pass was super reasonable and this family owned business impressed me more every time I went there. Outstanding facility with fantastic people, I highly recommend this amazing place!!

What We're About

Progress comes from regular weekdays, not big resolutions. We coach classes six days a week and the gym is open any hour, so there's always a time that works. And there's no sign-up fee.

Questions we get

Is there an initiation fee?

No. You pay for the membership you pick and that's the whole number. No sign-up fee, no annual fee, and nothing that turns up on your card in March.

What does 24/7 access actually mean?

Download the app and your digital barcode gets you in at any hour, starting today. Want a keytag too? Grab one at the front desk during staffed hours, Mon–Sat 5am–7pm or Sun 10am–2pm.

Do you have childcare?

Open 7 to 11am and 4 to 7pm, Monday through Friday. Included with group training. On a gym membership it's $40 a month per child for unlimited days, up to 90 minutes a visit, or $15 a visit, up to 90 minutes, if you only need it now and then. A parent has to stay in the building either way.

I'm starting over. Will I fit in here?

Yes! We run low-impact classes and yoga alongside the WODs, and we accept SilverSneakers. Not sure where to start? Ask at the desk and we'll point you to a good first class.

What classes do you run?

WOD, Lo-WOD, Strength, Circuit, Cycling, Lo-Cycling and Yoga, coached six days a week, Monday through Saturday. Two ways in: a group training membership includes every class on the schedule, or drop in for one class, three or seven with no membership.

Where are you, and what about parking?

We're at 300 1st Ave W in downtown Kalispell, with a lot beside the building and street parking on both sides. In July, give yourself an extra minute.

How do I cancel?

The desk can do it while you wait, or over the phone on (406) 752-2438. Give us 15 days before your next billing date to stop that payment. We'd rather you leave easily and come back later than stay because leaving was a hassle.

Do I need to book classes ahead?

Reserve group training, cycling and yoga through your member account, especially at the popular times. If you're not sure how, the front desk will set it up with you the first time.

Not covered here? Ask us.
