I've been really into working out recently as well as trying some yoga as well, which is basically physical, mental, and spiritual practices and movements from India.
Interesting, I know yoga is very popular right now, but I didn't know it's origins. I need to work out more too.
It was credited that Hindu Upanishads were the first people to practice yoga.
I don't know much about Hindu culture, but it's cool to know they basically invented yoga. 
Yeah it's really interesting, Yoga gurus also introduced yoga to other countries in the West in the late 19th century.
I need to start doing some yoga, I can't believe it's been around in the west for so long.
In the west it has basically just become exercise, but in Indian culture yoga is more meditative and spiritual.
