I'll give you some breathing exercises that you can do to, well, improve your breathing! Breathing for relaxation, for energy, to increase your diaphragm strength. I've got 'em all.
Training & Qualifications
I love to breathe. I also love to not breathe (as in, I like doing breath-holds and other freediving-related stuff). If you tell me what you need I'll go and do some research to identify an exercise that will work well for your needs. If you're just looking for an intro then I'll do that too.
