When I talk to people and they realize I'm a yoga instructor, I've received multiple reasons and excuses why they have never tried it before. Funnily without me asking if they practice yoga asana. It's like when you tell someone you're vegan and they say they only buy locally sourced meat. Anyways.
Yoga does not need prerequisites. Just start wherever and whoever you are. And see what the practice sparks in you. Maybe its relaxation, maybe it's flexibility or strength, maybe it's more presence or stillness or anything else. Try to have an open mindset for things and don't let fear of something new or unusual stop your from doing things for yourself.
