Felicity Huffman is no stranger to fitness. She's a fan of running and has participated in triathlons. But Huffman has a new fitness love -- she's getting addicted to Bikram yoga. The 45-year-old Desperate Housewives' star says "As you get older, you get stiffer. Doing yoga has shown me that flexibility is as important as strength."

Bikram yoga is nicknamed hot yoga and for good reason. When following along with Bikram's series of 26 poses, you'll be doing so in a room set to 105 degrees Fahrenheit (some classes may not set it quite so high). The idea is that your body is more flexible in heat, and the hot atmosphere warms your muscles more quickly. In addition, it's said to reduce the risk of injury, promote sweating, and release toxins from the body.
