Man, I hated doing that for OSHA respirator clearance

For real this shit is the worst. I didn't know exhaling could be painful until doing this. And they make you do it so many times!

Right?! The worst part for me is that there is absolutely no resistance to breathing out. I mentally expected it to feel like blowing up a balloon or something, but it's just an open tube

Yeah! On a mental level it makes the entire exercise feel pointless.
