I recently decided to try and get more active physically. I'm nearing 45 and felt sluggish. I attend college full-time, work part-time, and take care of my family at home. I had no energy and was a couch potato. This New Year's I decided to change this. I am now doing aerobics around 140 minutes a week and run a mile a day. I'm hoping to increase this. I also quit smoking!!!!
