This morning, I dropped off the car at Downtown Toyota and decided to walk the rest of the way to work. That was actually a good work out (by my low standards). If I walked directly from home, it would be another 15 minutes and 0.8 miles for a total of 3.5 miles and 68 minutes by Google Maps standards (it was actually pretty accurate for today's walk time).
I'm definitely feeling the pains of being overweight and old. I think I'll incorporate this walk a couple of times into my week's sparse exercise schedule. One thing I'll definitely NOT do is lug my backpack with a laptop in it. My legs and knees are fine but my shoulders are killing me.
