RMFF is the most friendly & inclusive, best outfitted, and least crowded gym I’ve ever had the pleasure of being a part of. It’s become like a second home.
Not only do they have every piece of equipment you can imagine (plus some you never knew existed), every single employee and trainer is out on the floor using them – leading by example.
Every time I’ve thought I might feel uncomfortable, there’s been a friendly face, ready to show me the ropes, excited to see someone trying something new.
I love this place so much, I actually posted this review, deleted it, then posted it again, just so I could give them 5 stars twice.
I love this place! The staff is always friendly and the place is always clean. After being stuck in a couple different gym chains since moving here it’s great to find a place that has a feeling of positivity and community.
I’ve been going here for about 7 months now and it’s a good gym. They have a lot of equipment and plenty of space. It is only busy during rush hours, and even then it’s manageable compared to other places I’ve been (5-6 ish). There are a lot of personal trainers of all varieties that operate out of RMFF as well so if you’re into that it’s a good place for training. Definitely a solid gym with a nice staff that keeps the place clean. Not much more to be asked for.
The absolute best gym in Denver! They always keep the gym clean, the staff is super friendly, and everything is always stocked. LOVE coming here.
Love this gym! Great environment and supportive of all fitness goals! Top of the line equipment and always clean! The boxing and muy tai classes on Tuesday / Thursday’s can’t be beat!
Clean Gym! Staff super knowledgeable and very nice. GREAT! Deals!. if your looking for a gym this is the one!
I’ve been lifting here with my trainer Charis for around 6 mos & love it! The staff is super supportive and friendly, and the equipment is up to date & clean. Not too busy that you are waiting around, but good energy. Also, great coffee shop right next door 🙂
I love this gym. Clean, lots of equipment, experienced personal trainers, and a friendly community. I recommend this gym to anyone who wants to take their fitness to the next level!
Great staff and plenty of equipment to bust out a tough workout of any kind. Veteran friendly.
Best place to workout in Denver, plenty of equipment, awesome staff, phenomenal trainers, if your serious about fitness and taking it to the next level RMF is where it’s at!!
