In the late 90’s, the Staver Foundry of Virginia, Minnesota produced replicas of the famous Thomas Inch challenge dumbbell. These solid globe dumbbells weighed 172 pounds but the handle is slightly thicker (2.47″ vs. 2-3/8″ on the original.)

Thousands of athletes have tried to lift the Inch Dumbbell but only a few have succeeded. You’ll need a very strong grip if you want to add your name to the list. There IS a secret to lifting the Inch Dumbbells, something that we’ll cover on another occasion…
