I don't tend to watch Fitness YT often, but one channel that really stuck out to me was Natacha Oceane.
She just makes a way better impression than most female fitness youtubers imo, and her marathon & various army / navy fitness tests have pushed me towards bettering my own performances.
I have to add Arnold here. The golden one since he seems to be doing mma and running instead of just weightlifting. That one actor who played thor in the marvel movies, don't remember his name.
Ethan Suplee! I’ve been a huge fan of his since Mallrats and while I miss seeing him play the derpy fat guy, his physical transformation has been truly inspirational.
(I was scared for Kevin Smith though. I’m glad he lost weight after going vegan, but the first time I saw him after his dramatic weight loss I legit thought he had AIDS)
