Hammer Strength/Tim Krumrie
Tim Krumrie, the Cincinnati Bengals All-Pro nose tackle is shown here with a classic globe dumbbell in this early advertisement for Hammer Strength equipment. The dumbbell shown (yes, it was a dumbbell) once belonged to the great French strongman Apollon.
Krumrie was well-known for his incredible hand strength, which should be an essential part of training programs for the game of football. Krumrie's specific grip routine can be found in The New Bodybuilding for Old-School Results by Ellington Darden.
