Next click on the X Axis and Y Axis buttons to deactivate them and Select Control>Scale in the Tool Bar. Scale the Torso on the Z Axis as shown in Figure 2.

Go ahead and Choose File>Save at this point. Name the File Human Torso 01 and hit Return to save it. When working on a project, get in the habit of saving your work often. Saving sequentially numbered models using File>Save As... is also a good idea. Save a new copy of a model after each significant change that you are happy with.

Click on the X Axis and Y Axis buttons to reactivate them and then click on the Mir U button. This will activate mirroring of the U steps of the Torso model. Any change you make to one side of the object, while using the Push/Pull Tool will mirrored across the X Axis. Select Reshape>Push/Pull in the tool menu and begin to reshape Torso.

Working in the Front view and Right view windows, select the V-step that lies approximately where the base of the rib cage would be and begin to reshape to look more like the base of the rib cage. Notice that as you move a CV the corresponding one on the other side of the model moves as well.
