Gym influencers

So I decided after christmas i’m starting the gym. I have a trip to the Dominican in August and I wanna look my best. I’ve been to the gym before for a school course so it was to get the goals of the class and get stronger, not targeting certain body parts in weight lose. I can’t afford a trainer so I was wondering who everyone’s favorite female gym influencer is. Someone who posts their workout routine and shows how to do the workouts right. Specifically ones with big bums and great glute workouts😅😂
