Some experts
say that you can't develop the size of your rib cage once you reach a
certain age - about the early twenties. It is certainly true that the
cartilage binding the rib cage stretches more easily at a younger age,
but we have seen too many older bodybuilders improve their rib cage size
to believe that this cannot be done. It is just a matter of time, effort
and patience - like so much else in the discipline of bodybuilding.
Remember that
the best way to force a weak body part to develop is by using a variety
of Shocking Principles to increase training intensity. You can also use
techniques like forced reps, Rest/Pause, three-quarter movements,
Staggered Sets, or anything else that will force the kind of development
you need.
