I get it so bad at my age (very late 40s), I don't mess around anymore. I have well over 30 years of lifting behind me. Sheesh. Kill me now.
If I am going to do any pressing, I use sleeves (2 or 3 ply from Lifting Large), all other times, bands for counter pressure. I also use wrist wraps (24" Convict from Pioneer Fitness) for all back, shoulder, and arm stuff. I used to use APT for all my gear but, well, they seem to have gone out of business, so these other two sources have begun selling APT's main product lines. Pioneer also makes custom belts, FYI... Pretty cool stuff.
I would love to argue there is one answer for how to keep it away but there just is not. I actually talked to a board certified Ortho Doc that specializes in the area about it. Sadly, he told me it is the price of admission. Ouch. There are exercises that form will keep it at bay, there are others that, no matter what we do, it will be pain. Some we can work around, some we just can't. So, mitigate, mitigate, mitigate.
For heavy pressing, I use sleeves. For everything else, bands. Anything that could result in me turning my wrist results in me using wrist wraps. If I stick to this, I walk away pain free. If I screw up and flare up, I switch exercises to anything that doesn't hurt... sad, sad.
