Running routine and general exercise stuff

Starting yoga this week. And jogging/power walking/aerobic conditioning at the gym. Basically, I want to be more flexible and have more stamina. Stronger is a minor additional consideration.

Thing is, I know that I shouldn't be running every day, but what about yoga? What about some other aerobic exercise?

Oh, and I found this exercise regimen that sounds like a good idea: http://www.coolrunning.com/engine/2/2_3/181.shtml

The name of the website makes me laugh.
