Jacqui Briggs leg day brutality

[Rei]

How do you get 4 spear knees in? Is it just luck, spam 4 as fast as posible, or perfect timing? I've hit the brutality once. But when I try to hit 4 spear knees in practice I've only done it once out of 100 tries...

its just that challenging. the timing has to be perfect
