What’s bullshit is when people say a certain method is the only way to train and everything else is inferior bla bla bla...the same can be said for diet methodology, high carb , zone, CKD, keto etc. etc.
it's like religion people are so extreme and exclusive in their views and get hung up one thing at the expense of everything and everyone else!
Kettlebells, sled dragging, prowler pushes, body weight circuits, hill sprints, low intensity walking, barbells, dumbbells, machines they're all just tools to use.
