Rigflex is useful to add simple soft body actions to parts of a rig. It gives stable, first order simulation. No collisions, no overshoot, straight forward baking after the animation is done. Just select the required deform bones, and the required key-frame range, and hit 'Bake'. Click 'Revert' to remove the effect.
