It's good you started young. I talk to a lot of people who say they can't start exercising now as they've never done it (regularly), so it seems the earlier you start this habit, the easier it is to keep your practice.
Sounds like you've got quite a competent workout going! I like that there's a lot of variety packed in there, so you don't risk getting bored of the same. Very intense, too.
Qigong is definitely on my list of things to check out, though I'd like to try with a teacher at first and there are no events in the summer.
