Any studies that you know of gradually increase the volume and tension? Or just the volume? I have seen where writers talk about the value of volume. How valid is the research? Also wouldn't it be logical, if gradual increases (progression) in tension causes hypertrophy and counteracts RBE, wouldn't the same thing be evident in progression of volume. I am not talking about extreme volume, but volume that builds upon itself like adding a set of progressivly heavier weights each workout, like I stated in my Pyramids post.
