Swimming is Going to Be My Biggest Challenge

I went to the Aquatic Center this morning with the intention of doing laps for 20 to 30 minutes. I lasted about 10. I guess I will just need to ease into it, too.My current training schedule calls for 2 sets of swimming the first two weeks, but that's based on 20 to 30 minutes, so I guess I will need to do more, shorter intervals until I build up my strength. I know my form is not the best, so I will have to work on that, too. I spent about 10 minutes in the water doing resistance exercises against the pool wall. The good news is that I was able to get out of the pool without killing myself- a very a big accomplishment for me.
