I used to swim five times a week, but I got a shoulder injury three years ago that I'm still recovering from, and thus haven't been able to swim during that time. I don't really like doing other sports, so I did some home exercises to at least keep up some muscle, but the cardio suffered immensely. I can hugely tell the difference tbh, I really miss going to swim. They gave me some sort of injection recently, hopefully in two weeks or so I can (extremely slowly) start building up again. I was told to start at just 4 lanes, once a week though

4 lanes, ooft, that must be killing you, being such a swimmer.
4 lanes a week is not even worth getting in the pool from my point of view.
Not being a swimmer or sports person, I used to do 120 lanes every time I was in a pool, I did not swim a lot, but when I was in a pool, I loved it. And I'm a fat bear
So for you being a proper swimmer, hearing to do 4 lanes must be terrible. I hope you get back to your form soon, we are pretty much still young people, those injuries should not happen to us, but hey, that's life...
Yeah, I'm sure changing will take longer than the actual swimming (even though I'm not allowed freestyle yet, only breaststroke, which is boring) and yeah, it's a bit disheartening, but at the same time, it's been three years since I did ANY swimming, and if my shoulder doesn't immediately go bust again, it can only go upwards from there

. Plus, it's not like I would be able to do anything near what I used to swim anyway, since I've become so much weaker.
120 lanes is really not bad though

. That's more than I usually did!
the unit lane, is that 1 way 1 time or back and forth = 1 time
That's one-way. Confusingly, even a "lap" is only one-way in swimming.
