I do lots of stuff throughout the day that I'm sure keeps me fit. I have a GSD/Malinois mix that I have to take on a long walk daily...normally at least two miles...or he's neurotic. I also take him and the rest of the dogs (Corgis) on a daily walk around our 13 acres. They do much more than me, I just kinda hang back and let them run. I then have all the animals I tend to, fit some riding into the mix, cleaning house, chasing a four year old, lol...lots going on. As far as a strutctured workout, I do a kettlebell class. I try to get in at least 4 days a week. Kettlebells really keep your core strong and you become very aware of your body posture. I find it helps with riding because I know right away if I start to slump or bunch my shoulders up, two things that I have a bad habit with.
