@ChristianRasmussen It may take a bit more effort for me because I have a pre-existing muscle condition, though I am not sure. One thing I did notice though is that practicing piano helps, so maybe after some time, if I have enough time to do that regularly, it will get better for me.

Also, I find it better to fix a miniature figure in some sort of holder and not keep it in one of the hands like the guy in a video. If it is fixed and I only need to move the paintbrush and not the figure itself, it makes it easier.

Yes, I have made my own holder too. It is a small container that fits better into my big hands then the hobby holders I have tried, so I bought a bunch of them (on sale) and reused the containers as holder.
I take top and use double sided tape or blu tack to hold my bits. Still keep the bottles in case they get a strange shape after some use (to hard a grip).

Found this newer picture of the kind of bottles, mine was scramble eggs. So a nice lunch and my new handle was born.

@ChristianRasmussen Bottle is a nice idea, do you use any anti-slip material?

I use a locksmith's vise in my garage when I paint something, not just minifigures. It is a bit bulky, but keeps everything fixed in place.

@DoctorEldritch anti-slip ? the double sided tape could be considered that or it is a no.
Is that pre-existing muscle condition something you have had all life or just developed in the later in life ?

@ChristianRasmussen Depends on the tape. There are anti-slip tapes made specifically, for example, tennis rockets or baseball bats often have them to make sure the grip is stable even in sweaty hands during the game. But they can also be used in other ways, like to make sure the figure holder or bottle, in our case, would not slip.

That is a chronic condition I have always had, my muscles are less elastic than normal.
