Gyms in and near Denver, CO

In a city with more running paths, bike trails, whitewater rapids, and scalable cliff faces than one person could ever conquer, Denver gyms have some stiff competition. Still, indoor exercise has its benefits, from providing shelter from the elements to granting a less risky way to try new things. At 24 Hour Fitness Denver, runners can hit the treadmill on a rainy day, and new rafters can work up endurance on a rowing machine before hitting the rivers. The Rock Lounge’s three-level climbing gym helps mountaineers learn good technique before they scale a real peak, and The Cycling Yogi’s Cycle/Yoga 30/30 classes help cyclists center their minds and stretch their muscles in a yoga-infused spin class.
