Yes you can do a bare minimum but without progress you may lose motivation. After a while you get used to the slightly better feeling and slightly better sleep.

May get bored with it only to go back to the occasional workout. That was me. I needed a more noticeable result. Progressing to complex bodyweight exercises is trickier. Lifting weights properly is technical enough, planche, even headstand pushups weren't going to happen for me. I made every form mistake you can make with weights. Mistakes with complex bodyweight moves halt progress.
