I just recently started learning to post.....now that is a workout. I was sore for several days later. I have heard some doctors say though that you can't count your normal daily activity as exercise, because your body will get used to it. I kinda can agree with that because even when you go to the gym you gotta keep increasing your weights, keep speeding up the treadmill, etc. in order to get anything out of the exercise. I ride almost everyday, so I guess it no longer counts for me. I love riding though, and after my ride I always feel better and have more energy, so wether you can count it as exercise or not, it definitely has its benefits.
