get better physical endurance

Finally, today I went back to the gym. I was very busy and used it as an exuse. Also because ones you haven’t gone….it seems to be harder to start up again. But today, I went and it felt great.
I hope to get a very good endurance before January 2010, that’s when I am planning to get back in the game (tennis). But before I can get back on the court, my cardio and muscles have to be in better shape. At least to be able to play matches on high level again. Wish me luck!

I am starting the couch-to-5k-training method. Wish me luck!
