Susan - heck yeah it's still cardio!
You'll notice I am proudly putting up my 10 minutes of elliptical as cardio
I can't figure out what I want to do today - i should do cardio since yesterday was yoga - if i take work home maybe I can leave at 5 and have time to take the buggies for a long walk.
(The buggies are my two english springer spaniels - I attached a picture)
