Aim routines

What aim routines do you guys do that actually improve your aim since for me aimlabs is hella boring and i cant just spam it for hours every day id rather play deathmatches but idk how much they actually make you improve

Oh and in my youth I played goalkeeper to increase my hand eye coordination

i personally use the MANGO MANGO MANGO strat

as someone who's been to both extremes (of not warming up at all vs spending more time to warm up than playing):

I always go in the range for 3-5 mins, if I feel like I'm aiming fine I queue
if I don't I play deathmatch until I feel more confident (sometimes it's taken like 4-5 deathmatches)

First 5 rounds are your warmup buddy, you go big or you go home.
