Everyone has their own unique story of their start on the path of yoga. Fostering a deeper interest using online classes, an app or Youtube is fine and dandy. Just know that you are getting mere drops of water in what is otherwise a vast ocean.
Just as planets have their place (alignment) and your home stands up due to the solidity of its foundation, so too does your body have a place (spatially speaking) and your practice is built upon the foundation of feet and hands.
I hope Yoga supports you in all that you pursue.
Namaste (bow me you).
