Back in the old days, “chest development” meant chest and ribcage expansion, not just bigger pecs.

Here’s a look at George Eiferman, a classic bodybuilder, who was famous for his chest development, on the cover of the February, 1948 Strength and Health Magazine.

Eiferman won the AAU Mr. America, AAU Mr. California and IFBB Mr. Universe titles.

In this picture Eiferman weighed around 190 pounds. You can tell that ribcage and chest expansion contributes greatly to the “look” of strength and power.
