I can only give my personal perspective here, but I see fitness as like brushing teeth:
It is something that you must do either way in order to stay healthy, but doing that alone probably won’t get you anywhere in life by itself.
Yes, it has to be done, but it won’t make a big difference with regards to moving forward in life.
By being fit you will not suddenly become rich, free, alpha, famous, enlightened etc., but you are simply making sure that you stop being one of the fat losers of society.
Being fit and looking fit is like having clean teeth. It is something that one should do automatically as a normal society baseline. By being fit you are making sure that you stop being below that baseline.
There are a lot of motivational videos on YouTube to go to the gym etc. where going to the gym is sold as “actually conquering life”, but in my opinion by going to the gym you haven’t conquered anything yet, except a little bit of self discipline, no, you just have started doing the bare minimum, just like brushing your teeth every day.
A lot of those gym bro’s are fooling themselves thinking they are now suddenly “at the top of productivity and motivation” while the real work begins after those basic hygiene factors have been covered and with all the things that no one else is doing after that.
Since it (the fitness) has to be done anyways, I cannot afford to sacrifice a valuable ZP stack slot for this and instead I am using those ZP titles for those life areas, that actually do help to bring me onto another level.
I think fitness subs are great for a few cycles to establish healthy habits (that one should have anyways), but afterwards one needs to move on to the ones that really help you move further in life.
Exception: fitness is your business, your life and blood as an influencer, or something comparable.
