Going strong

Last night I swam for about 30 minutes. I practiced my sprint swimming. I timed myself swimming 10 laps, then I had a break. My goal was to get faster each time. I did it! I am trying to be able to recognize my speed. Sometimes I don't know if I can swim faster. Anyways, I did this 5 times. I need to start adding something else in my swim workout days so that I am getting more accomplished. Swimming for 30 minutes just isn't cutting it. Maybe I can add cardio or weight lifting in there. Tonight is my spin class. I would like to do a little cardio before but I am working at my dad's today so I don't know if I can get there in time.
