Breathing

So how do you guys breathe when doing your FSPs and FBEs? Do you use the Valsalva maneuver? Pavel's power breathing methods? Breathe out on the concentric phase and breathe in on the eccentric phase? What is the correct way to breathe, especially when it comes to FBEs?

Discuss!

I think it's best to breathe the way that comes naturally, unless that involves holding your breath, or taking short, sharp breaths.
