For those that don't know, John Gill is a famous American climber. He started bouldering in the mid 1950's and is widely credited with being the first person to start using gymnastic chalk to aid climbing. His problems of that time were legendary, as were his feats of strength such as the one arm front lever.
Today John Gill is 76 years old and still enjoys exercising. Watch him in action. John you are an inspiration. Thanks.
