Coby Langford, UK Osteopath, is interviewed on GMTV with Lorraine Kelly and Dr Hilary Jones about the benefits of Yoga for the relief of back pain. When GMTV asked Coby how condfident she was that yoga could help back pain, she accepted a 4 week challenge to prove how effective it is. Coby was given a random back pain sufferer and taught her yoga for 4 weeks. The patient then came onto LK today LIVE to report the results.
