Get Hot Yoga's certified instructors help students burn calories and sweat out toxins in hot-yoga classes, available seven days a week in a heated studio. Choose the 90-minute Hatha class, which emphasizes proper pose alignment and breathing exercises, or master dance-like postures and sinister belly laughs in the 60-minute Vinyasa power class. Get Hot Yoga also hosts a Wild Card class, an open-ended 60-minute session that flows to the rhythm of each instructor's imagination by incorporating Hatha, Vinyasa, or a mixture of both. Instructors work with each student's abilities during all classes by modifying poses or upping the level of difficulty as needed.

The spa-like studio nurtures a calm climate with natural lighting and earthy tones, and lavender-infused frozen hand towels cool down and soothe muscles and olfactory glands after class. Students are encouraged to bring their own mat, towel, and water and should arrive 15 minutes early to check in and stash personal belongings and cubs on loan in the provided cubbyholes.
