Hey Mary, I'm not Cathe, but I can give you an exercise that she says aids in shin splints and helps prevent them. Its on her Push Pull video. Do you have a stability ball? You will need one for this exercise.
What you do is you sit on a chair with your legs straight out in front of you with your toes slightly pointed. The top of your feet are almost parallel to the floor. (As opposed to sitting with your knees bent for a normal seated position). Place the stability ball on the laces of your shoes. This is very important, it must be on the laces. (If your toes arent pointed slightly the ball would be on your toes, it won't work this way) Extend your arms out so that you are pushing slightly on the ball to keep it from falling away. To do the exercise you put pressure on the ball with your arms WHILE you pull your toes in toward you. This will kind of smoosh the ball between your feet and your hands. You should feel the results from this in the tibialis anterior, the muscle right next to your shin. In the workout cathe does this exercise in single count 16 times, then 4 times at 2-2 count and then another 8 times at single count. My fiance' has had shin splints and he says this exercise really helped him.
Hope this helps! Push Pull is a great workout so if you want to see it for yourself, you could always get that workout too.

p.s. If you do not have a stability ball, I suggest you go buy one, you'll need it for the hardcore videos anyway! And they are great exercise tools!
