I you still have shin splints, I use an easy, simple exercise to get over them. Sit on the floor with your back against the wall, and your legs stretched out in front of you. If you are doing the right shin, take your left leg and lift it over on top of the right leg and put your left foot down on top of your right foot. Your left foot will be pointing up and to the left at about 45 degree angle, and the edge of your left foot will be resting on top of your right foot where your toes join the foot. With your left foot, try to press your toes away from you, while resisting with your right foot you as you try to point them back toward you. It ends up being like an isometric exercise. Hold that for 10-20 seconds and do it 2-3 times per shin--you will feel the muscle on the front of your leg flex. Do this 2-3 times per day. For me, they are gone in a few days.
