Jim,

The tibialis anterior (shin muscle) is extremely weak compared to the hamstrings.  As a means of establishing fore-aft balance via dorsiflexion, it is further "hamstrung" by the fact it has to effect the movement of a heavy object, the torso/cm, through a long lever arm to change fore-aft.  The hams move only the light-weight stuff below the knee and via a shorter lever.
