If you're talking about Pavel, you might consider that "Power to The People"; "Beyond Bodybuilding"; and "Easy Strength" are all about barbells and strength. "Beyond Bodybuilding" is particularly interesting for its clandestine approach to talking bodybuilders into finding something more useful to do. "Power to The People" is a highly reductionist barbell program based on deadlifts and side presses with a barbell. "Easy Strength" is an attempt to make coaching different qualities for different sorts of sports, and its the source of the semi-famous 40-Day Easy Strength Workout, which was actually Pavel's program that Dan John now gets credit for for some reason.
All that to say: you can poo-poo kettlebells all you want but Pavel is a strength guy and is no stranger to barbells. He has 500+ pound pulls to his credit, and has coached his old man who's pushing 80 years old to high 300s pulls in meets. He has a permanently effed up elbow and can still press the 48 kilo Beast with either hand, which is about 2/3 bodyweight for him. So you might want to try having a clue about Pavel before writing him off as a bodyweight maven fit only for gymnastics, parcours, or similar skills sets.
