Sledge hammer training has always been a very popular way of building forearm and wrist strength among many oldtime strongmen. Based on the leverage principle the sledge hammer makes a very efficient workout tool as it can provide a great deal of resistance without the need for a lot of weight. Here, Murl Mitchell of Los Angeles, tests his wrist strength with a pair of very interesting looking sledge hammers. Look closely and you’ll see that Mr. Mitchell is wearing glasses which he just slightly and gently tapped before levering the hammers back to the vertical position. It was said that these hammers weighed 25 lbs. apiece — Superb. Mitchell also placed second at the Sr. Nationals Weightlifting Championships in 1945 in the 123 lb class with a 470 lb. total.
