A great way to keep the energy in the body balanced is through doing energy flow exercises like qigong and tai chi.  I have been watching and follwing a qigong instructor named Lee Holden.  His website www.exercisetoheal.com sells his DVDs.  His mother also does a DVD for seniors so that most people will be able to enjoy the flow of energy. 

The following is a clip from several years ago where Lee attended the Awesomeness Fest and gave a demonstration on qigong.


Jeff Chand is also another great qi gong insturctor and accupuncturist with a channel on YouTube called ThinkVitality.
