Wow, that's quite a commute you have there. I understand not wanting to take the extra time to go to the gym, so why not get a few exercise DVDs you can do at home? I know that you're tired and would rather relax, but fitting exercise in and making it a habit gives you the extra energy to make it through the day. My life has changed drastically since I made it a habit to exercise every day. I work full-time, and I'm also a full-time undergraduate commuter. That half hour to an hour I squeeze in of exercise really helps improve my stress levels and puts everything into perspective. I tackle it and move onto the next obstacle.

Best of luck on achieving your goals. There are many inspirational and knowledgeable individuals here.
