Reviews

"I recently started CrossFit, and I am so happy that I did. I had been going to the gym for years, but never quite understood if I was doing things correctly, or if I worked out enough. 5280 CrossFit is like having a gym, a motivational coach and a personal trainer all in one. Now that I have experienced the knowledge, the people, and the facility that 5280 CrossFit has to offer, the old gym is now a distant memory."

− Nick W

"If you are looking for a CrossFit gym that gives you the absolute most for your money, this is the one. This is one of the nicest, most well outfitted CrossFit gyms out there. Do yourself a favor and get in with them now to have a CrossFit experience the way it is meant to be."

− Nate B

"I've been on the CrossFit kick for over 3 years, I've dropped in at a lot of boxes around the country when I travel for work - 5280 CrossFit is up there with the best of them. Owner/Coach Jason Grubb is a great coach, he pays close attention to your form all while pushing you to reach your maximum potential."

− Jeff M

"The facility is amazing and Jason is a coach I can trust. He knows what he is doing and he cares about each and every member. He pushes me to be my best, but knows my limitations and designs a workout that helps me discover what I CAN do.....not what I cannot do!"

The Science

“High intensity exercise yields results that differ in kind from moderate-intensity efforts, not just in degree (but in physical results). In a peer-reviewed study in which one group exercised at moderate intensity for 45 minutes on a stationary bike and the other group did high-intensity intervals for 20 minutes and burned the same number of calories, the high-intensity group lost nine times the fat. Human growth hormone (HGH) and other compounds cascade into the blood of people who sprint as though a monster is chasing them and lift heavy objects as if earthquake survivors are trapped underneath. These hormones signal the body to burn fat and build muscle. The grim trudge-to-nowhere on a cardio machine, or miles of brisk walking, does not unlock this chemical cascade.”
