I do think that all makes since (people respond to different ranges, etc), but the argument I have heard and wonder about is the claim that it changes the appearance of muscle.
I’ve heard people claim that it will make muscles appear denser or something like that.
Now, I have heard the only way to change the way a muscle looks is heavy, explosive movements which effect myogenic tonus. Beyond that, I haven’t heard anything convincing beyond “lifting causes hypertrophy, no matter what the range.”[/quote]
That’s bullshit. A muscle will look different at different sizes. You need both high weight/low reps and low weight / high reps for decent muscle growth. If you are trying to address a weakness in a muscle group that can be addressed using specific excises that shift load to the weaker spots, but in general. Soft vs. hard looking is more diet dependant.
Some old school guys say train heavy for a “dense” look all else being equal that’s probably true, but this topic is pretty broad and I could drone on and on about it. I suspect you actually have a more specifc question. If so, lets here it, that’d be easier to answer.
