Hi, I was hoping someone could help me out. I'm in my 20s and never swam competitively or had much training. For the last year or so I've been swimming at the pool at my gym, it's probably 13M. Rarely, I go to a 25 m pool. I have a couple questions and would really appreciate if someone could help me. 1. How much is it harming my progress that I swim in a 13 m pool? 2. All I really know how to do is swim freestyle - usually about 45 minutes, stopping for 30 s every few minutes - is this dumb? where can I learn what I should be doing? 3. I seem to get really tired and almost emaciated (sorry can't think of a better word) after this swim. Why? Swimmers I see tend to put on a lot of lean muscle? 4. I also really enjoy lifting weights - has anyone founda way to balance and improve at both? If anyone could answer any of my questions that would be awesome. Sorry, I can't seem to figure out how to skip lines.
