Mountainside Fitness Avondale

Best gym Mountainside has opened so far love the cold plunge and infrared sauna!!! Super convenient location off the freeway, staff are incredibly knowledgeable and inviting!

I have so far had a really good experience on this new gym. Laura here at Avondale was very helpful and answered every question I had. I’m really exited for this gym and I enjoy all the classes they have.

The gym is very open and has all sorts of equipment for any exercise. Not only is there is a steam room, there is a sauna and cold storage plunge! Great spot to workout!

I've been to gyms all over the state and abroad. By far the best. The staff is nice, although they wear ear pieces. Who do they think they are the CIA. Just joking. This place is legit and not too crowded.

Love the infrared sauna at this location. Excited to try the cold plunge, and the outdoor turf area is amazing while the weather is still cool. Never have trouble finding equipment even when it’s busy.

Such an amazing location! The cold plunge and infrared sauna are a great new additions. Very open facility with lots of equipment. I'm not sure where these negative reviews are coming from. All of my interactions with staff were pleasant. I can't wait to start my fitness journey here :)

They have good equipment and steam rooms. Only had one bad interaction with staff. It was a woman at the membership desks. Other than that it was good

The experience at Mountainside is the best in AZ! As a local, I have tried many gyms over the years, none of which compare to Mountainside. The towel service is a blessing and saves me so much time in and out of the gym. Plus a cold plunge, steam and sauna. All of that and more for families for an amazing price.

Attended a training at this location last Saturday--beautiful facility! And all of the staff were super friendly and helpful. Highly recommend it!

I have been waiting for a Mountainside to open here! The staff is so nice, the treat us like family. The facility is top notch and the variety of equipment they offer is amazing. My grand kids love the childcare and I love that I can leave them in a safe, fun environment. The best gym in the area for sure!

This is a beautiful and clean gym. This childcare is unbelievable! They are going to have a hard time getting kids to want to leave. I went in on opening day and every employee I encountered was very friendly. I've been to many Mountainside Locations and this is by far the best!

This is Mac from Goodyear, AZ. I am 55 years old, played college football (great gym) and competed successfully in bodybuilding competitions. On top of that I traveled the world several years for business and worked out in gyms on multiple continents. This gym is the best I've ever been to. Very large, great staff, and a TON of room between benches and machines in the dumbbell area. I love this gym; best one ever.

Mountainside truly outdid themselves with this location…. Absolutely gorgeous! My jaw dropped when I saw the locker rooms… sauna, steam room and cold plunge! The equipment is state-of-the-art and tons of it. Even during “busy” times there is no waiting for machines. Not only is the facility great but so is the staff. The General Manager, Stefanie, is very hands on and truly makes sure that every member feels at home.

Very clean and towels are always available! Always find plenty of workout options available anytime i come!

Kate is the best also!

Mountainside side fitness in avondale is one of the best gyms I have been to. The staff are very helpful, and the equipment works all the time.

Gym was packed today and there was still free equipment. Always clean and the equipment is stuff I haven’t seen elsewhere . No pool or hot tub like ESPORTA , but it has a steam room and cold plunge and sauna .

Been going here for a few months now. I love that they brought in more equipment, they’re up to date. My kids also love the childcare.

First time visit and was a very clean and great gym! Front desk was very nice. Thank you Kate!

Great gym! New equipment, friendly staff, lots of parking, tons of cardio machines and very very clean inside!

Membership signup, personal training with Julian, the MCafé and amenities have been great, better than expected, and better than other leading gyms in the valley.
