first time posting on here

im 16F and 4'11,, and my current weight is 115lbs,,

it doesnt sound like a lot,, but i carry it differently,, and i end up looking bigger

i have no idea where to start my fitness journey, cuz im in an academic situation at school, and i live in india, so running here on the roads doesnt feel safe at all... gym memberships are too expensive, and my grandma keeps making heavy-oily food 💔💔 help
