i think you should always have something to strive for in improvements because its hard to stay motivated when you think theres nothing to gain anymore.
At some point the concept of "motivation/ being motivated" does'nt exist anymore, you just lift weights mechanically without a second thought. You don't think about "improving", but you think more about "maintaining" what you've built, and somehow this is a way to improve something that can barely be improved anymore.
I'm not saying kyomu should stop "improving", i'm saying he should just keep doing what he s doing without taking it too seriously, and enjoy what he's doing already, that's the point of lifting weights; enjoying lifting weights, not to strive for "results" you cannot even visualize. If you stop enjoying doing it for what it is and "strive for improvements" you're going to lose your motivation over the time.
It's how you understand "improving" that should change. It's more of a mental thing than physical one in the end.
There's more hapiness down the road for kyomu if he focus on enjoying what he's doing instead of striving for results that won't even make him happier. That's the way to steroid use, especially for someone who obviously reached his maximum potential as a natural. He's taking it too seriously, he's admiring people who don't really deserve it, I thought he'd be smarter than that. He's obviously way too much into this at the moment, and who knows where it will lead him.
I think he's bordeline fanatic/obsessive with his hobby, to the point it looks like it's not a hobby anymore...
Maybe he should improve the mental perception he has of himself instead of improving his body indefinitely...
