Yeah, I think that’s right about hypertrophy training. I’ve plateaued in some strength areas and just don’t have the equipment (mainly bigger weights) to push it further.
And yeah, I’m definitely better emotionally and mentally on days that I workout. But I think one has to get to a certain level of fitness to feel that. Like, if the pain or tiredness from working out outweighs those benefits then you just think there aren’t any benefits or you don’t notice them. In my experience about a month of regular exercise is enough to get in that kind of shape. But it’s obviously different for everybody.
