Even the most minor of injuries can sideline a runner from being active for an extended period of time; some are even determined to run through the pain and risk injuring themselves further. Danny Dreyer's technique, ChiRunning, can help prevent these injuries and promote the ability to run faster, farther, and with less effort at any age.

ChiRunning employs the deep power reserves in the core muscles of the trunk, an approach that evolved out of such disciplines as yoga, Pilates, and t'ai chi. Dreyer's training principles are broken down step-by-step to accommodate all levels of runners.
