Why Green Door Fitness?

Because we strive to be energy independent and to get outdoors.

We are working on becoming a certified Green Business through the city of Denver, we recycle, reuse, and try to reduce our waste by using cloth towels and our own water bottles. We don’t have paper cups or paper towels.

Our motto is We workout hard at Green Door so you can play outdoors! We will have a calender of events posted at the gym and would love to get your ideas on the calender too!

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. So when life happens you are ready! That creates a sense of ease and enjoyment when you are playing with your family, walking the dog, or when tragedy strikes and you need to run for help. We want you to be prepared for anything, which means being Green Door Fit!

Our Team

Matthew Hammel

Owner / Trainer
Matt is a native Coloradan who grew up in Denver. His first passion was football but a hamstring injury forced him to pursue other avenues for his love of physical challenges. In 2001 he graduated from Adams State College in Alamosa with a degree in Exercise Physiology. In 2001 he obtained his personal training certificate from ACE and is also a certified massage therapist.

Besides helping his clients meet their own physical and health goals, Matt loves running, mountain biking, and hiking. He’s climbed 46 of Colorado’s 56 fourteeners with his dog, Sasha. Always seeking a new challenge, he is currently training to rock climb the wall in Yosemite National Park.

Matt loves to share his love of the outdoors with his wife and daughter. He’s currently teaching his six-year old daughter, Luna, to ski. "One thing I’ve learned," he said, “is if you don’t take care of yourself, you can’t take care of others.” Being healthy is wealthy!
