I do. I had a nighbor who also homeschooled and before she transfered to California, we would take our boys to the track at the school and run them around the track. The track had stations around it where you do balance, pullups, situps, parrallel bars, monkey bars to go across, and a few others that I can’t remember. We would start at one station, have the boys do what they could (for pullups we did a hang, and on the parrallel bars we just said hold yourself up as long as possible) then run to the next station. We then brought balls for catch, or kicking, or badmitten raquets and birdies for cordination type activities. Some days we don’t go to the track and just do the balls and games in our yard. Trying to teach jumping jacks was pretty funny. We have younger dc though, mine 6 and 2, hers 8,6, and 2. They would race and try to best each other so it was fun all around.
You might have to take some time to teach them what you want them to do, then they can excersice on their own while you do your workouts.
