Track my exercise with Google?

Hi! Has anyone developed an easy way to track their workouts with Google products (calendar, docs, spreadsheets, etc.)? I have been trying to use the calendar, but I haven’t found an easy way to do it. The survey function of the spreadsheets function seems to have promise (Did you workout today? Did you do this…?), but I just haven’t been able to settle on an easy solution. I am trying to track my weekly cardio and weight training. Thoughts?
