Harry L. Good started training in 1924 and by 1930 he had turned professional. Only a couple of years later, in 1934, he won the World’s Strongest Professional Strongman title. Harry worked for Bob Hoffman for some time, but he decided to open his own barbell company afterwards and kept it running for 37 years.
Unassisted one leg press, in the picture below, is an amazing exercise for developing leg power and coordination at the same time. Harry recommends mastering unassisted Two Leg Press before you attempt the one leg variation.
Thanks to healthy lifestyle and regular exercises, Harry managed to live 95 years! If you are interested in training practice and lifestyle of old strongmen, I would strongly recommend you to check out this resource.
