I got one. I ended up accidentally losing 25lbs when I did this, but ymmv.
Basically, about 6 years ago, I got into freediving while on vacation. Once I got back to the real world, I got obsessed with training to hold my breath for longer. So I started doing breathing exercises just after I woke up and just before I went to bed. Each session took 15-25 min and was done lying down to minimize the danger from passing out. I used an iOS app called Apnea Trainer (no affiliation besides satisfied user), but there should be a ton of apps available on both app stores if you search ‘apnea’. You can also read a ton of information (including safety tips) by googling ‘CO2 tables’ and/or ‘O2 tables’.
After dropping the 25lbs in my first month of training, I started looking into why that might be and, from what I’ve found, training your body for longer breath holds can increase resting metabolic rate.
You should have a look at the Buteyko method. The basic premise is most of us suffer from chronic hyperventilation, which comes with a lot of issues including obesity, and the method aims at training us to better tolerate higher CO2 levels.
Training for max breath holds would also help you tolerate higher CO2 levels and breath less.
Not after I got back from vacation, no. There’s not much opportunity where I am and I didn’t have training partners, so I the only thing I could do safely was dry training.
