Hi, keep in mind that im relatively new to oly lifting, been doing it for 3 months ect.
I tend to use quite a while on my warmup, around 20 minutes.
Here's what my warm up usually looks like:
Foam Rolling on 2-3 different areas
Dynamic ankle mobility work against wall 2-3 minutes
Ankle mobility work with barbell on my knees
Shoulder mobility work with rope (rotations over my head)
Overhead squats with band (without and then with weight lifting shoes)
Some dynamic hip mobility work
Rotator cuff work
Also i've had Overhead squats in my work out routine pretty much the whole time, so i wonder if i need something more or if i just need to fix something with my mobility in my T-spine section or my hips, or perhaps some other place.
