I need to do something about my fitness. I lead a very sedentary life and have done so for the past 3 years.

today I met a work colleague and we had a short walk to an office where we were doing a presentation. It was only a 5 min. walk but I was short of breath and had trouble talking, which is ridiculous.

I'm going to start with a short walk this afternoon, and I'm going to try really hard to walk every day, even if it's just a short walk.

I've gained weight too in the past 6 months, although my gain seems to have plateaued. I'm not really worried about weight loss at this point, I'm more just really worried about building up my cardiovascular health.
