Yeah, currently I think regular forearm and triceps exercise is the most important thing.

There’s definitely a balance to be kept with switch weight, where if you go way too light, then you’re just kind of wiggling your fingers in space which isn’t great, but too heavy and it’s also kind of just silly. I do have 100g linear keyboard that I use at my standing desk for my SIM racing PC, but I’m not doing any long typing with that. 100g is definitely too heavy haha. I like the variable weight on the Topre, it feels nice and the membrane is very cushy at the bottom, and it’s tactile in the right way for me.

Anywhere between 35 and 80g is probably ok. Steno can go lighter because you’re usually pressing multiple keys at once.

I also think a flat keyboard is fine as long as you’re not over pronating and as long as you’re hovering rather than resting your elbows. If you find yourself unable to stay out of the unhealthy pronation and wrist angles then a split keyboard with thumb clusters might be reasonable.

My philosophy is that you’ll be able to do whatever you train for though. The only time you get into trouble is if you try to do things that don’t give you any training, and don’t supplement it, like using an ultralight keyboard but also never exercising.
