Fitness Feuds (highly controversial but the production value is incredible)
Athlean-X (periodically)
Supertraining (periodically but i do like that his channel is like the garden variety of fitness from powerlifting, nutrition, bodybuilding, general health)
Dave Tate (lots of good info but i find Dave Tate to be a hilarious person)
Larry Wheels (entertaining just to watch his lifts, not much info though)
Mike Israetel
John Meadows (periodically)
used to watch Ric Drasin a few years back too as it was fun to hear stories about the good old days
Nick's S & P
Dave Palumbo (regardless of your opinion of him i do find his content entertaining and informative)
Jeff Nippard
Top 3: hard to say as i get into different shit each week but i'll go with Fitness Feuds, Athlean, and Mark Bell
