You may want to try positioning the torso by including it as part of a larger kinnematic chain (perhaps by positioning the head). Performing an IK operation on a single object, especially an ultimate parent such as the torso, does not allow IK to distribute the solution – the torso is trying to move and rotate. Because it's the legs parents, its slight rotations are probably being passed down to the "quivering" legs. Damping allows other objects in the chain to contribute a correspondingly higher amount of rotation to the soultion. In so doing, it somewhat resembles "stiffness". A damping of 0.0 allows the joint to move freely, 1.0 will freeze the joint, and values in between stiffen the joint accordingly. Hope your man is running now! – Phil
