Without yoga, no one would be able to find his or her center, resulting in an overabundance of post-office Wanted signs and frantic searches through shopping-mall lost and founds. Call off the search party with today's Groupon: for $30, you get one month of unlimited hot or power yoga classes and a mat rental for the first class at Red Dragon Yoga in Mill Valley (a $175 value).

The experienced instructors at Red Dragon Yoga unite mind, body, and spirit in supervised Bikram and power yoga classes. Referred to as "hot yoga," Bikram yoga depletes the body's toxin population via tidal waves of sweat as students bend through a series of 26 poses in a room heated to 105 degrees. Like slow dancers at a junior prom, joints, muscles, and ligaments gently warm from the heat of the room, allowing for maximum flexibility. Power yoga builds strength and flexibility in a heated room as students perform continuous flowing movements and postures, which vary based on class and instructor. Both 90-minute classes allow students to progress at their own pace, so beginner and veteran yogis can bend together in peace. Check the online schedule for class times.

Natural light pours into Red Dragon Yoga's studio, illuminating perfectly struck poses and imbuing spirits with vitamin D. Hot showers and a changing area slough off postclass sweat, and the Red Dragon Boutique outfits students with yoga apparel and grants Groupon customers a 10% discount off one full-price item. Mats are available to rent, and one free rental is included in this deal.
