The dogs around here have a pretty easy time maintaining fitness – they get, in all but the most exceptional of cold, road walks of at least 1.5 km a day (Sam and Sally usually get 2 road walks), runs at the farm (shorter now but generally I walk 3 km and they run for the full 45 mins+) , training time (every day, every dog does SOMETHING for their brain), and at least half an hour outside keeping me company while I do outside chores. They run up and down stairs, do balance games (tho I don’t have a balance ball or peanut). We end up balancing working cardio, muscle and brain fairly well. If somebody comes up lame they go on moderate rest – ie leash walks and walk and brain work only until they are sound. Luckily around here lameness seems to last a day or two at most and doesn’t happen often. I think it noteworthy that Thea and Sally are the most likely to come up lame – they are hard on themselves always!
I’ve got the dogs cross training down to a fine art.
My fitness? Not quite as organized! When at work I used to open the student weight room for 90 mins once a week after school and ride the stationary bike while the teens worked out. Here I walk, I wood (mainly loading and unloading – I’m literally not strong enough to lift the splitting maul over my head), I garden in season and recently have started riding. I’m also trying to much out 4 stalls twice a week as part of my fitness plan. That uses muscles not commonly used in daily work and gives me an aerobic push taking the cart to the muck heap. I need to remember to take care of my fitness as well as I do the animals if we want to have the most fun playing together.
