Earlier this year I wanted to start a gym routine to gain some muscle mass and lower my body fat percentage. I found Jeff Nippard's youtube videos to be a good resource for my purposes:
He's a bodybuilder/powerlifter/coach with a focus on evidence-based exercise and diet advice. I've heard him cite people like Mike Israetel and the MASS report at https://www.strongerbyscience.com/mass/
I like that his videos tend to be concise, and he does a good job of being clear about which of his recommendations are backed up by research and which are opinions based on his personal experience/preferences.
