Bikram yoga became popular after a study concluded the high heat was the main reason grandpas normally emerge from gym saunas feeling relaxed, limber, and totally nude. Experience the benefits of warmth without wishing for a blindfold with today's Groupon: for $49, you get one month of unlimited Bikram Yoga classes (a $180 value) at Bikram Yoga Rockville Centre.

Bikram yoga consists of 26 poses and two breathing exercises that center, strengthen, and lengthen every muscle with the muscle-melting powers of a 100-plus-degree room. It's designed to cater to all skill levels, allowing practitioners to choose the rigorousity of each workout. Sweat out toxins and enjoy mind-expanding stretches while breathing deeply. Afterward, you'll leave focused, with a cleansed, centered, and worry-free glow. Rockville Centre students should remember to drink plenty of water prior to class, wear something light and fitted, and bring bottled water, a mat, and a beach-sized towel––all of which can be purchased or rented at the school. With a flexible schedule that offers 54 classes a week, ranging from early morning to evening classes, students can easily schedule their classes around late-morning reruns of The Price Is Right.
