Arm fatigue after switching to MTB
I've been road biking for years and this year I switched to a mountain bike (GT Aggressor Pro). I've been training on flat road and usually after about 5 miles I'm getting severe arm fatigue in the elbow pit/forearm area. I'm thinking it might have something to do with bike geometry or improper adjustment. I do like to have my seat high like on Road Bike, maybe that's causing it? Is there some kind of adjustment I can make to handlebars, etc.? I'd love to hear any suggestions you guys might have!
I'm 5'11" and bike frame size "L" (it's 2018 GT Aggressor Pro, 27.5" wheels)

Road riders who switch to MTB often keep weight too far forward - likely what you are doing since you are riding on flat roads. When I started riding off road seriously after 30 years of nothing but road, I got a small piece of advice I remember every ride - light hands, heavy feet. It took me a while to stop riding my MTB like a road bike and instead ride with weight centered at the BB.

maybe add bar ends so you can pivot your wrists outward?

I'm not sure. Maybe move all stem spacers under stem to lift bar? I don't have much experience riding mountain bikes on flat roads.

I started commuting on an mtb. The two stress relievers for me were good gloves, and then Ergon grips with bar ends. Game changers....

What most have said here. Keep on riding and you'll get used to it. I'm your total opposite and started road a few years ago BUT at the same time I'm still mountain biking. I mix it up every week between both. Maybe that will help too in the long run.
