Have you ever tried yoga? It's been popular since the 1980's. I'm an instructor
I tried it once
You should try Hatha yoga, it emphasizes physical exercises to master the body
Really?
Or you could try Zen yoga, it's part of the Zen Buddhist tradition.
What is the difference between Zen yoga and Hatha yoga ? 
Zen yoga is based more on Buddhism, it's one of the largest religions in the US now behind Christianity, Judaism, and Islam.
