Thomas inch dumbbell
The Thomas-inch dumbbell is a dumbbell with a very thick handle and two solid spherical weights.
history
The dumbbells with weights from 63 kg to 78 kg were introduced around 1905 by Thomas Inch (1881–1963), a British strength athlete and title holder of Britain's Strongest Man (1910).
measures and weight
The specialty of the Thomas inch dumbbell is the extremely thick handle. The unliftable 172 , the heaviest version of the Thomas inch dumbbell, is 2 3/8 "(6.03 cm) in diameter and therefore very difficult to grip. It weighs 172 pounds . Due to the heavy weight and poor grip, it is often impossible even for strength athletes for whom the weight is not a challenge to lift the dumbbell with one hand.
Thomas Inch Challenge
Thomas Inch offered a price of £ 200 for whoever can lift the 172 bar with one hand. No other athlete succeeded in this at the time, but Thomas Inch occasionally demonstrated it. In 1967 the Scotsman John Gallacher managed to repeat Thomas Inch's exercise. Mark Henry is the first man who could move the Thomas Inch dumbbell off the floor and lift it over his head .
