Stress, like a river, can overflow after unusual weather patterns, rapid bank erosion, or a barrage of cannonballs. Return to calm waters with today's Groupon: for $39, you get a 10-class card at Haute Yoga (a $139 value), with locations in Solana Beach and Carlsbad.

Haute Yoga hosts state-of-the-art studios dedicated to teaching a plethora of yoga styles in an eco-friendly environment. In beginner classes such as Yoga 101, amicable instructors break down yoga fundamentals and modifications. In the mildly warm Vinyasa classes, students melt from movement to movement with each breath in an athletic approach to yoga for all skill levels. For yogis who strike poses with aplomb, the Hot Power Sculpt class intensifies postures with hand weights. In all classes, students need a yoga mat, a water bottle, and a towel (towels and mats are available to rent for $2 each per class).

Slough off the outer layers of strain with easily accessible outdoor or covered parking, and steady yourself for mind- and body-bending in the comfortable lounge area. Haute Yoga's eco-friendly practice studios feature energy-efficient air heaters and tatami-style flooring made from recycled, VOC-free materials. Round up the members of your homeowners' association for a dose of heat-activated motivation from the experienced instructors at Haute Yoga in preparation for the annual block-wide Twister tournament.

Haute Yoga occasionally offers a free week of unlimited yoga. Groupon holders may combine today's deal with the first-week-free offer.
