Tons of things in our society came from a religious background and were liberated from it. Galileo studied the stars and argued against the Pope to become closer to God, that doesn't mean astronomy is mysticism.

For people who sit at a desk all day, like most people here I would imagine, doing even just one hour of yoga a week can have a huge influence on their physical well-being (not to mention posture). Doesn't need to be more than that.
