Donna Wilkinson: We are up to our final walking warm-up and this is going to be to help your shins, so you dont shins splints in there, for athlete to help you run with better form. I call it the duck walk sometimes; we call it AT walk. Basically you want to get on your heels, keep your toes up in the air and out to the side just a little bit. It is going to look a little goofy walking on those heels, really keeping those toes, working those shins. You want to really have nice, strong shins so you dont get shins splints or have other challenges.
