I agree with the advice in general, but advice like this could appear anywhere and apply to anything. Not relevant to music specifically.
So we shouldn't be giving it? Please stop posting stuff like this (I see you doing this thing in a lot of threads), you're contributing absolutely nothing to these conversations. If you don't like the stuff people post or have nothing constructive to add, instead of making some snarky remark you should just
not post in that thread.
To get on topic, I have to agree completely - Going to the gym almost every single day has been one of the most helpful things for me as a musician. Getting enough exercise helps you sleep better, keeps you feeling healthy (which improves your focus), counteracts the hours and hours of sitting you're gonna be doing as a producer, and it's a great way to clear your head. I go to the gym at least 4 days a week, plug in my headphones, and just spend the whole time I'm working out analyzing the songs and asking myself questions about how I could incorporate the things I hear into my own music. My phone has a "Gym Thoughts" note document on it, and every time I get an idea or realize something about a song I just type it in and continue my workout.
