Cycling or Jogging - What does more good?

I will vote for cycling. It works up all your major body muscles, and its more fun!

Do both. How about adding swimming so you can do triathlon too?

Seriously, if you live within 10 miles from where you work, then you should be biking to work anyway. That means you can get a whole lot of cycling in during time that you would normally be driving a car.
