Comment on Is possible to learn to swim, just by reading a lot about it?

I am skinny - if I am not actively swimming in fresh water I am sinking (sea is different but sea comes with waves which is an added complication). If I am tired or nervous then I have to fight with my subconscious to be calm and stay safe. So I would add mental strength to the list for a first time swimmer. And even then I’d say don’t go out of your depth.

Ha! I’m skinny to and my wife always tells me, floating in water is just a learnable skill
I’m just drowning as well…even if I try to control my breathing to stay afloat, my legs will drop and it’s just a constant struggle to stay tensed, breathing while trying to keep a full lung to have more volume…
She meanwhile just floats by relaxing and doing nothing.
I’m still not sure if it’s really just technique or her boobs are acting as a life vest…

Yeah, it’s really frustrating when someone with higher body fat that floats like a cork tries to tell you how to do it.
Technique can’t overcome density. I will say that I got slightly better at it after learning to SCUBA dive (or maybe I just got fatter). In scuba, you move up and down in the water column by adjusting the range of your breathing. You basically try to get your neutrally boyant setpoint at 50% lung capacity. To go down, you try to control your breathing from 0-50% and to go up, you breathe from 50-100%. It made me slightly better at keeping my lungs really topped up with air.
To float, I basically have to hold my lungs at max capacity, and then exhale-inhale as fast as possible, which is unnatural and takes concentration. I usually have to use my arms for a little bit of upward thrust through that breath.
There’s no lungs in my legs, so those will sink no matter what. People claim you can “use your core” or some other BS to keep your legs afloat, but the fact of the matter is that if your upper body is positively buoyant and your lower body is negatively buoyant, there will be a rotational moment pulling your legs down, and it can only be counteracted by external application of force (i.e., kicking your feet). I can either float on my back with a mild amount of kicking, or i can do like a face-in-water deadman float, and just pull my head out of the water occasionally to quickly breathe.

Hehe, that’s exactly where I got my idea from to control my breathing to try to float ;-)
