Hey, so i start off by going into a workshop map (aimbotz).
1. I practice for about 10-20 mins hitting headshots only with usp, glock, deagle ,m4 and ak.
2. Once im done i go into a community server ( I use baited) and then just chill and practice against others and higher ranks for a few hours.
3. I then join my premade if they are online and we go into MM or Faceit.
4. Hope this guide helps you, remember this is MY warmup routine so it may not work for all people. This is aimed for lower ranks or gold/mg
