Question on progressive overload

My goal is to reach an athletic lean physique with visible muscles, not looking to bulk extensively.

Ideally, it will be more like Tom Holland’s Spiderman rather than Chris Hemsworth’ Thor if that makes sense.

I started at 80kg, 168cm. I’m making progress and have cut down to 73kg with some visible toning, adding weights along the way.

So what do I do when I eventually reach my goal? Is there a need to load more? Or do I keep to the final working weight and do the same till the end of time?
