Booty workout :”)

I’m getting back into fitness again and I’d like to better shape my body (who doesn’t). I wanted to ask what best grows the butt and gives it that nice round shape. Does anybody have any Workout YouTube channels they can recommend or a workout routine in general? :) I’ve recently lost a lot of weight so I’ve lost my butt kinda. I mainly want it bigger and I need some real help with the side booty cause it’s sad to look at the moment..

Talking about that I guess I should ask what’s the best tasting protein drink there is/ how much grams of protein should I intake for the workout. Last one I got it was not the best..

Thank you so much.
