Until the advent of Bikram, yoga was associated mostly with unlawful bending and the ubiquitous "om". Now, the modern twist on the ancient technique has, for better or worse, turned yoga into a trend on par with weight training in the '90s. Classes of post-work and pre-cocktail young professionals gather in the handy City studio nestled near Old Street (there are also studios in Queen's Park and Kentish Town). Bikram enhances the yoga experience with heaters, causing yoga-doers to sweat copiously in the name of detoxification. Secretions aside, it's kicked off a new fitness trend and brought yoga into the 21st century.
