YogaSource, St. Louis

The instructors at YogaSource strive to make yoga accessible to everyone, regardless of age or ability. To meet that goal, they offer eleven types of classes split between two studios, which are kept at different temperatures to accommodate those who prefer to stay calm and cool during practice, as well as those who like to sweat as they stretch. Yoga basics and intro to Hatha classes lead newcomers from pose to pose to build a foundation for future practice, and may incorporate props such as straps, blocks, and donuts that dangle just out of reach. Advanced options include power Vinyasa, where students flow through rigorous poses in 90-degree temperatures believed to help increase flexibility and promote detoxification, as well as the open-level class—known as The Practice—in which instructors and students attempt handstands and other challenging feats.
