I think it's a matter of keeping the hands aligned with forearm and not having pressure on the write joints themselves. I try to keep the palms of my hand (the same part you hit with in martial arts) on the "wrist rests" instead, and I've had zero issues for years. For me, the biggest problems I had came from using various mice and never finding a good one until I moved to a MacBook and learned the trackpad. Now I've literally adhered a magic trackpad 2 to the middle of a Kinesis Advantage 2 keyboard and I love it. It translates back and forth between using the laptop and a "docked" setup better than anything else I've tried over the years.

The kinesis advantage (now Advantage2 LF) has been my mainstay keyboard over the last 20 years, both professionally and personally. I too adhered a trackpad, although mine is an Ergo Mini touchpad: https://ergonomictouchpad.com/ergonomic_touchpad.php

I immediately bypassed the aesthetics side of MK and went straight to functionality; the kinesis has probably been the most reliable piece of hardware I've had over the years (with the exception of a key-repeating known issue that has been resolved with the advantage2)
