I had my first swimming lesson today. We practiced putting our faces in the water, blowing all the air out of our lungs underwater, flutter-kicking, and some front- and back-crawl things. There was only one other person there today (there were supposed to be two) and the other person hadn't been in the water as much as I had. Therefore, I ended up doing more actual swimming than she did. That's ok. At the end of the class we worked on treading water. I'm very excited to be really learning to swim.
Afterwards I was pretty tired - I'm not a strong swimmer at all, and swimming across the short end of the pool (ok, half-way across the short end) multiple times was tiring. The instructor said that it would get better over the next few weeks.
