I just thought of a great idea! Today when I was down with Queen the girl that owns the place had her horses out in the let out Area's, so I had no place to lunge Queen. So while I was grooming her I was thinking of something I could do to exercise her without being in the fenced in area's. We'll I ended up taking Queen for a walk out in the desert. I put a stud chane on her just in case she got out of hand for any reason. She loved it. So after we go for a walk, untill it gets cooler and her feet get use to the hard ground I'm going to take her on 1-2 mile jogs. She will trot but I can jog along with her to get into shape and we'll both be getting in shape. Plus it's fun. So that is my workout plan for cardio.
