one advantage of swimming over most other sports is you can do it on a hot summer day and actually sweat less than you would chilling at home

@coolbean i miss swiming

@tisanae its great i just came back.

had to cut it short by like half an hour cause i had a sudden weird feeling across my torso. i suspect like a gnarly stomach cramp but it felt like it went all the way up into the shoulders. accepted that was probably the signal that id hit my limit and immediately swam to the edge, pulled myself out and laid on the floor for a while. then just barely walked back to my bag and laid on the grass for a bit until i was able to confidently get back up

my arms are so fucking sore oh gosh. my physique is gonna thank me for getting back into swimming though. my goal atm is to like make it through the swimming certifications. gold (or rescue swimmer, the one right after it) or bust. first i gotta practice my dive jump again though i totally fucked it

@coolbean i like the soreness of swiming (tho i rarely need to move too much as i float a lot (not as much as my mom but )) i miss that
woah really cool goals

@tisanae yea. i can float but i need to let it happen, it doesnt happen naturally. i hope that as i lose weight (at least in fat) that might become easier

@coolbean there might be others parameters, i don't understand how my mom is doing it, like she sits in the water and she's halfway out of yhe water

@tisanae its purely surface area vs weight afaik

@coolbean it's the volume of displaced water against weight, but that do not make sense in that case

@tisanae hm true but i think surface area also has an effect because of surface tension or whatever. idk im no fucking physicist i can barely explain the venturi effect

@coolbean nah surface tension is negligible for that

@coolbean @tisanae it's volume vs weight aka density

@snacks @coolbean to be absolutely precise its weight of the volume of displaced water against weight of the object

@snacks @coolbean thats how boats can be denser overall than water

@tisanae @coolbean water density is pretty constant usually only varying from salinity tho

@tisanae @snacks but that doesnt make sense because you actually float most easily when your entire body is on its back at the surface compared to upright despite the fact you would be displacing lower pressure surface water

@tisanae @snacks technically you could do it on your chest too but your face would be underwater which isnt ideal

@coolbean @tisanae actually yeah, how tf does that work

@snacks @coolbean i think volume kinetics

@snacks @coolbean like doing the volume of displaced water considering human as a cylinder instead of a sphere

@coolbean @snacks pressure is irrelevant as liquids are incompressibles

@coolbean @snacks and one side of it is a lot less denser than the other, so on the side it floats more easily because a lot less of it is under the water

@tisanae @snacks ok yea true i was thinking of total weight of water in which case oh yea thats why you float easiest with your body against the surface of the water

@tisanae @snacks which in my defense is also still referred to as water pressure particularly while diving, thats just not a straight up density increase

@coolbean @snacks thats just pressure as in force the water is exerting against u from all sides

@coolbean @snacks (thats why u need special air mixes when diving deep with bottles else ur lungs aren't strong enough to breath it against the pressure)

@tisanae @snacks well actually the reason you need specialty mixes is because if you kept the same mixture as surface air, youd get nitrogen narcosis and die. so you need to add inert gases just to keep the total amount of oxygen and nitrogen in check lest it become toxic to you

@tisanae @coolbean those mixes are to prevent too much of certain gases dissolving in your blood which will either just gas out when you go up or act as narcotics from my knowledge

@tisanae @snacks diving is scary

i just wanna get back into form and maybe get some swimming certifications. silver seems straightforward i just gotta swim for 15 minutes straight and manage a distance of at least 400m and dive 2m to grab a dive ring twice and dive for 10m distance (with pushing yourself from the edge. for gold you have to do it mid swim so no push). rest is straightforward though i do need to practice my jumps i didnt commit to my dive jump enough and was still partially upright and got water way up my nose

@snacks @tisanae so yea. need to practice endurance, diving and dive jumps. makes sense. also speed when going for gold

after that come the lifeguard certifications and id really like to get the junior lifeguard one because it comes with a very adorable patch i can put on my trunks or whatever. also i guess i could become a lifeguard as far as job opportunities go which, for a tranny, is a bigger achievement than a 6 figure/year programming job tbh

@coolbean @tisanae losing weight actually makes floating more difficult, having more fat helps you float

@Clover @tisanae yea more volume thats less dense

@Clover @tisanae buoyancy is fucked up tbh

@coolbean @tisanae @snacks water isn’t very compressible at all, water density at the surface vs a meter down is basically the same

@Clover @tisanae @snacks yea i got it right i was thinking of water pressure which is total weight of water pressing down on you which *is* depth dependent

@Clover @snacks @tisanae i got it wrong i mean

@coolbean @tisanae @snacks I was looking at places I could learn how to free dive near me and there’s one place I might look into registering at

it’s the most appealing type of diving to me

@Clover @tisanae @snacks yea free diving seems nice. i wish i could get the hang of snorkeling cause that would be the nicest to me cause it means avoiding scuba gear for which ive just watched way too many cave diving accident videos to trust with my life

@coolbean @tisanae @snacks
you are so cool bean ^^

@coolbean @Clover @tisanae cave diving is just so much more dangerous than regular diving it's basically asking for trouble
