Exercise? What ever happened to tossin hay bales and carrying 10 gallons of water 4 times a day to keep the trough filled in the winter when the pipes freeze because the frost is 6 ft deep? You both like doing something different,insted of riding the horse, take them for a walk, or jog, its perfect for your exercise and their ground manners.
this is a relly god idea to show kids that you not only have to take care of them and not just the horses and teaching them ways to do so.
