Pose your way to the pinnacle of vitality and strength while ascending through degrees of difficulty and degrees of Fahrenheit during classes in CorePower's temperature-controlled studios. The raised heat level expedites the breakdown of fatty acids, delivers more blood to the muscles, and reduces the chances of injury. Start at level one, where you'll be comfortably introduced to proper postures at room temperature, then ascend to the humid human heights of advanced yoga in a detoxifying 95 degrees. Yogis of all skill levels can step into the 97-degree atmosphere of Hot Power Fusion, during which a combination of poses from hot- and power-yoga classes stretch over the course of one rejuvenating hour. Classes vary by location, so check out the full schedule here.

The health benefits of yoga are well known: regular practice increases strength and flexibility while eliminating stress and uniting body and mind. If you’re a runner or cardio-happy exerciser, yoga will help to de-stress and ease your over-exerted joints.
