Inner peace is hard to come by, requiring complex negotiations between spleen and kidney. Find harmony more easily with today's Groupon: for $55, you get 10 heated yoga classes at Lakeview Yoga in Kenmore (a $110 value). All 10 sessions must be used within 60 days of the first session.

Lakeview Yoga hosts hot and power yoga sessions in a heated practice space that encourages deep stretching and detoxification as students gaze out on Lake Washington. The studio's weekly class schedule gives pupils ample opportunity to loosen tightly spooled muscles and ligaments within invigorating waves of heat. Hot-yoga classes challenge attendees with 90 minutes of sturdy postures intended to imbue bodies with strength, flexibility, and the confident balance of a tightrope walker sprinting across a bridge. Power yoga similarly heats the space before the instructor leads pupils through a flowing sequence of asanas, encouraging students to use the seamless transitions, standing poses, and floor work to focus their minds on controlling the movements and switching their handedness. Although the studio advises attendees to bring their own yoga mats and towels, rentals ($2 each) are available to guests who pass the mandatory background check.
