There’s a lot of reasons to do backbends in Winter.
First, they are warming. Second, they are rejuvenating, bringing feelings of optimism and uplift during dark, depressing days. Finally, they are second in importance to inversions as tools that help you acknowledge your fears around growth and challenge. Requiring a commitment from the core that we've all but lost in modern posture, backbends are sometimes scary. They thus take courage and pluck, and when they’re done correctly, there’s no better feeling — in asana, anyway.
Bottom line is that they feel good and nearly always turn that frown upside down. Come work on them with me Saturday, February 9 from 2:00-4:00 pm!
