Every morning right after a shower, and every night just before retiring.

I've been doing various types of stretching, and practicing various forms of yoga and Tai Chi since I was in my early teens, and yoga and Tai Chi have actually become quite addictive to me. It is not unusual at all to find me in a park, off-the-trail, at the top of a climb, or just in a tranquil natural setting, spending anywhere from a few minutes to well over an hour going through a routine to relax my body and mind.

I highly recommend all three activites to anyone interested in increasing their flexibility, improving their physical strength, and learning how to better focus their mind, and I also believe that these activities will reduce the chances of certain types of non-impact injuries as well, but the benefits with regards to improving personal performance are undeniable.
