I love this gym! The childcare has been such a blessing as I was struggling to find comfort in leaving my kids and the girls have always been so patient and helpful with my journey. They tried time and time again when my youngest cried as I left and now he loves going in! They are like family, they know me and our boys and my children remind me to go daily so they can go play with friends! Emily, Faith, Sam, Delaney and all the girls I can't remember, thank you for being amazing!!

Been going to the gym for 4 years now. Have been taking my kids since day one. The girls in the children are so welcoming and amazing, I always feel at ease leaving my kids there. They listen to everything I have asked and requested when it comes to my children. Hard to trust anyone with your children now a days but I trust the girls there.

I honestly can't wait until my membership is up to expire. I've been with this gym for about 2 months and I never feel really welcomed nor get the help I need. I asked the receptionist at the front desk about the massage chair my phone wasn't scanning to get the massage. It was my first attempt and I told her it wasn't working and she just told me it should work, but didn't bother to come check to see if there was an issue or if I was simply doing it wrong so I just left and she told me "thank you for coming in" after she se... read more

I've reviewed the gym in the past however, I feel it is only fair to update as I have begun to visit other Mountainside's and realize that when compared to other Mountainside's this one is likely the worst I've visited. I frequently take the extra 5 minute drive to go to the Surprise location because the childcare at the Happy Valley location is borderline dangerous for smaller kids. I am fortunate to be able to come to the gym during hours that most children are in school and I still am overwhelmed walking my little kids in... read more

It's always daunting leaving your children in the care of others- but we are BEYOND pleased with how well by the staff in the kids care program treats & cares for our little ones. They know our children's names by heart & are excited to see them each time we come in (which makes dropping them off all the more easy on my anxious mama heart). Our children love their "teachers" and so do we! We take advantage of every "date night out" service they offer, and have refrained from switching to the bigger fancier (pricier) gym down... read more

With the family membership at Mountainside in Peoria Happy Valley we have had the best experience. Our young kids get to play at M kids under the Incredible supervision of Emily, Delaney, Treesa, Ashley, Tori, and so many fun and kind staff. Because we have so much trust in the M kids staff, my spouse and I can workout and make health and wellness part of or daily routine and it has been life changing for us. My spouse loves taking Spin classes with Emily whose playlist is always changing and is so much fun, and I enjoy the ... read more

I've been a member for over 7 years and I have nothing but good things to say about this location. Equipment and facility is always clean. Casey and the rest of the Faculty are always welcoming when I enter the facility.

I've been a member of mountainside for 8 years and have been coming to the Peoria location for the last 5 years. They have a half-court basketball setup, spin classes, yoga, daycare. No pool. There is a sauna. The machines are nearly always in working order. The free weight area is a bit cramped, but there are plenty of benches and dumbbells. You don't have to wait for more than 5 mins maximum if you're flexible in the order of your workout routine. The aerobic area has updated treadmills, probably about 30 of them, and I've... read more
