 Re: scuba diving equipment maintenance basics?
I hope it's okay if I ask the question here. Has anyone of you use one of those lung volume trainers before? You know, where you breath with a resistance to increase your lung volume. I saw that on the internet and was curious if it really works. Thanks in advance for the answers.
