Heating a yoga classroom can increase students' circulation during workouts, unlike increasing the degrees in a geometry classroom, which results in students becoming more obtuse. Raise your fitness IQ with today's Groupon: for $39, you get one month of unlimited classes at Bikram Yoga Honolulu (up to a $150 value).

Bikram Yoga Honolulu's instructors teach students of all levels a rejuvenating sequence of 26 poses, staging sessions in a room that has been heated for increased blood flow, muscle performance, and safety. The schedule teems with 49 class times, seven days per week, affording attendees many opportunities to improve their physical and mental health, flexibility, and sweat-to-clothes ratio. A combination of standing, seated, and photo-shoot poses systematically strengthens the major muscle groups as students' tendons, joints, and organs fill with freshly oxygenated blood, which restores the youthful energy they once possessed in their baby pictures. Meanwhile, the equatorial temperatures help bodies eject perspirable toxins and to sink deeper into each of the sustained stretches.

Though Bikram Yoga Honolulu sometimes features a discounted price online, this Groupon still offers the best deal available.
