light work on a daily basis. totally individualistic
I walk my horse around 1/2 hr each day.
Mine has arthritis in his hind legs. I like to keep him active so I ride him 2-3 times a week and lunge him with side reins 2-3 times a week as well. This keeps him active but keeps him from constantly dealing with the pressure of a rider. The more active your horse is the less the arthritis will bother them (normally) but don't push him. If you make him to active and can make things worse for him/
