Sun salutations are a necessary ritual that keeps our solar body from growing angry and burning libelous graffiti on the Hubble telescope. Help keep cosmic peace with today’s Groupon: for $59, you get 10 hot-yoga classes at YogaFlex in Commack (a $160 value).

YogaFlex’s heated studio space intensifies the stretching and flexing of its yoga classes with temperatures as high as 105 degrees. The tropical heat helps bodies stretch further, sweat out toxins, and burn more calories than a backstroke relay in a Jello-filled pool. Beginning and veteran students alike break a sweat in Classic Hot Yoga sessions, which consist of 26 balance-challenging poses that help circulate freshly oxygenated blood throughout the entire body. Hot Silent Hour classes put students in control of their own practice, allowing each attendee to monitor their own postural alignment with minimal instructor guidance. Barkan Hot Vinyasa strings together a dynamic sequence of traditional and modified poses that flows as gracefully as a French lullaby. YogaFlex helps students compose themselves after class with onsite showers and changing rooms for men, women, and mannequins.
