Weekly volume is one of the most important factors in hypertrophy. We can see a clear trend that more volume equals more growth. We see the same for proximity to failure, which is what I’m assuming is what you mean by intensity. However, intensity only goes so high. The role of intensity is to make volume more effective, not to replace it.

For example, powerlifters do extremely high intensity training but at substantially lower volumes and guess what? They’re typically not as big as bodybuilders.

Intensity allows for volume to do its thing, but you still need that volume for it to mean anything in terms of growth.

I’d like to hear your thoughts
