A simple exercise would be, e.g., sit on the bench and place a 25, 35 or 45 on the ground and place your toes under it. Lift the plate in a movement that's not unlike that one does when tapping one's foot.
The tibialis anterior is the muslce that runs along the front of the shin, that is, it's opposite of the calf mucle.
This worked for me when I had painful pumps when walking in the area of my body (thought it was shin splints at first).
