Green Door Fitness
If you live in Denver, you know that there are a variety of places to help you get fit. It's a challenge to know where to go, but at Green Door Fitness, we're here to help you get fitter and feel better about your body and yourself. Our fitness center is much different than other places. We know that the gym isn't synonymous with fun, but we try to make it that way.

We know that you want to learn how to do things safely, learn about the equipment, and take your fitness needs to the next level. Local gyms have one significant benefit: You are close to them and actually go to them! If you choose a gym that's far away, you're less likely to go. You're wasting money on a Membership you're not using, but you're also sabotaging your body and health.
Services
To us physical fitness is the ability to carryout daily tasks with vigor and alertness, without undue fatigue and with ample energy to enjoy leisure time pursuits and to meet unforeseen emergencies. Put easier we want our workouts at Green Door Fitness to be challenging and harder than anything you have in your daily life.
I named it Green Door Fitness with a double meaning because I want to encourage mindfulness for our planet in terms of recycling, reusing and making more with less, and also to encourage us to work hard indoors at Green Door Fitness so we can play hard outside in our Green Plant. There is always a trainer roaming the "floor" to help give you a personalized workout at any time of day, no appointment needed, no extra charge!

What a great gym!
My husband has been diagnosed with muscular dystrophy and Parkinson’s and he couldn’t get off the couch without help. After a few months he is a new man! Tying his own shoes and not dependent on me anymore. Green Door Fitness is the answer for all of his problems. Thanks Matt and Aaron!

This place is the best! I was in town for the week and called to see if they could do daily passes. Not only did they accommodate me, they really took the time to see where I was at, tailor each daily workout and really challenge me. Matt, Chelsea, Brett and Aaron are so nice and welcoming, I felt like part of the family immediately. Kind of considering moving to Denver just so I can join this gym! Thank you all for such a wonderful week!

I’ve been trained by the owner of Green Door Fitness, Matt Hammel, for nearly 20 years. He is an excellent life coach as well as a conscientious, concerned, yet tough trainer. Green Door Fitness is a warm and inviting community. Everyone becomes a friend.

Hands down would recommend Green Door (GDF) to anyone looking for a friendly, inviting, and community-oriented gym. I love being able to workout alongside people of all ages and sizes, and feel like I fit right in.
GDF is super unique, in that they provide 1:1 attention to every gym-goer via customized workouts and training. The trainers are AMAZING — very knowledgeable and supportive.

This gym is extremely unique in the way they set up your workouts and the energy of the space. There is a community feel which is important when choosing a gym for myself. I’ve never repeated a workout twice and I feel significantly healthier since I started going. They challenge you and work with you to be healthier and better. Highly recommend!

Green Door is a fantastic gym! It is great to be able to go into a gym and have a skilled trainer always available to help you advance your goals (or leave you alone, if you're in a more self-directed mood). The trainers are friendly and good. They all have different styles, but consistently they do a great job of asking what I want and adapting the workout to my goals (whether it's just what I want to work on in any given day, or long-term objectives). Green Door is a very welcoming, well-equipped space. They've taken good measures for COVID, limiting the space to 5 reservations at a time. I feel

Absolutely the best gym experience I have ever witnessed! For the price of a normal gym membership, I am coached and pushed to meet my personal goals by a very talented team. When I walk into Green Door Fitness, all instructors and even the owner knows not only my name, but everybody's name that walks through the door. With COVID, there are never more than three people working out and their mobile scheduling application allows you to set your workout time worry free. There is no better place to workout than Green Door Fitness!
