Breathing/Valsalva

[Panda]

Hi Rip, I’ve read pg 59 of blue book but I’m still not quite clear on this point.
On the final reps say on heavy squats I’ll tend to vocalize/grunt towards the end in order to lockout. Is that a bad thing ? ie isn’t that releasing some valsalva , hence tightness, at highest stress point in the lift. If I try to not do that however, I feel like I might pass out or something.

Are you doing the valsalva with your mouth open, as we recommend?

[Panda]

Yes I am

Vocalizing in short grunts is not losing pressure, unless you just exhale all the way.

Ok, good to know, thank you Rip
