Kaley Cuoco, who shot to fame on 8 Simple Rules and currently stars in The Big Bang Theory, gets fit in the saddle.

After she's done working, Cuoco heads to the stables to ride her horse, Falcon. It gives her a chance to escape from the stresses of her day and to get a great workout at the same time. Cuoco says: "It's the perfect combination of a mental and physical workout. After an hour, I'm exhausted. I work muscles I don't use otherwise: My legs, butt, core -- everything is sore."

For a change in routine, Cuoco finds fitness in another type of saddle. She loves taking spinning classes at her gym. She says, "Doing something I really enjoy has made a huge difference in my motivation level."
