Bikram Yoga Princeton's intensely heated practice space enfolds students in 105-degree air made velvet by humidity as high as 40%, urging muscles to relax and stretch further during athletic Bikram sessions. Instructors attentively lead students of all ages and fitness levels through two breathing exercises and 26 poses, using standing twists and seated stretches to methodically shepherd oxygen-rich circulation throughout bodies. The physical exertion, combined with infrared heat, encourages detoxifying perspiration, purging students’ bodies of dangerous toxins to make room for the more enjoyable toxins that accompany the weekend. Throughout class, teachers demonstrate proper form, fine-tune their instruction with verbal cues, and suggest pose modifications with hands-on adjustments. After practice, the studio's shower and changing facilities allow men, women, and sentient claymation figures to regain their composure.
