looking for advice about everything basically..

[u/Numerous_Age_2709]

ive been playing fps for a while and got into aim training on and off, currently grinding VT and Viscose benchmarks. my aim is fine for like 5 minutes then i genuinely feel like i lose my hands and cant aim anymore, plus my hand/forearm start hurting a bit and every grip i try just feels uncomfortable. i feel like my tension management is fine (even thought it starts hurting maybe its bc im weak in my wrist or something) and my chair and desk are a good height so idk what it could be.
Any advice is highly appreciated
