This is a great club! The facility is always being updated with new equipment. The staff is friendly and knowledgeable, there are many classes to choose from taught by great instructors. I highly recommend giving it a try!

This club might have the best environment I have ever seen. Everyone is so kind and willing to help. The MAC is professional, clean, and friendly. It is a community hub for Bigfork.

Staff and equipment are both outstanding. The facility is absolutely spotless.

Bill BGoogle Review

I love the MAC! I joined when I moved to the area about 4 years ago. The staff is always friendly and very helpful. It just went through a beautiful renovation/expansion.

When I do arrive to MT - I will be coming from Vegas...are we allowed to use the facility right away? Or does it have to be after a 14day wait?

Can the PEAK get that for the turf?

Nice job, Doug and Nancy!!

I came Friday and Monday and so impressed with the staff and facility. I told my husband, if it feels too strict I will see if I can put my membership on hold for awhile. The staff is awesome and makes everyone feel so welcome and the facility feels as welcoming as ever. They have crew that are constantly cleaning even after I scrubbed the equipment I used. The fact you are NOT selling day passes makes me feel super safe. Thanks for the great work and making us all safe.

why isnt the person coming in asked to wear a mask??

Doug... good FYI video, open the gates and let ‘er buck!

thanks guys and I am so glad to be able to workout

Looking forward to the lap pool lanes open for adult swim 🏊‍♂️

Thank you!

Thank you for everything you have done & continue to do for all us Mac members! 🙌 Can’t wait to get back in the gym!

This is awesome! Love our gym!

They do a good job

Returned to Montana Athletic Club Bigfork today. 👏👏 The club is IMMACULATE. It is a new experience for sure but there are so many safeguards in place for member safety! There are additional staff on hand cleaning and sanitizing, machines are spaced as possible, and cleaning supplies are handy to all. Everyone there was so welcoming and it was great working out with others with great attitudes. So glad to be back in one of my favorite places!!! Thank you Doug and Nancy!!! 💛
