So I'm starting up jogging again since my teenage years.  That's about 27 years ago.  Now that I'm older and more prone to injuries, I stumbled upon this running technique called chi running on Youtube.  It's based on tai chi and it teaches you to land on your mid-section of your foot instead of your heel.  By aligning your body and head in the most upright position with a forward tilt from the chest, you begin running.  It's how a baby learns to walk - the most natural and efficient way.  Thus, less energy is expended and injuries are prevented. Anyways, does anyone know if there are classes on chi running? Or any chi running instructor I can get in touch with?  Thanks in advance.
