ChiRunning Certified instructor, Coach Steve Mackel demonstrates the ChiRunning Body Looseners along with 4 additional dynamic exercises for runners. Working with the Sole Runners marathon and half marathon trainees, each Body Loosener is shown in order with explanations. When I refer to “C” shape I am talking about the specific ChiRunning Posture. You can do these even if you are not a ChiRunner because they are such a good way to warm up the body and turn the muscles on. Contact me or ChiRunning.com is you want to lean ChiRunning.
