Visegrip Viking Challenge Grip Contest
Some randon thoughts written on forum by diverse people:
“Considering Burkes back ground in the construction industry it’s not supprising he has a great grip (try using a hammer for a few hour with littke rest) but even then this is some impressive stuff”
“Size doesn’t quite equal strength, but the guys with the biggest forearms I seen were manual workers, construction, working on drills/jackhammers etc. Gripping, pulling, lifting relatively low loads for massive reps every single day. Not quite sure of a practical way to harness this to improve grip strength short of changing jobs though.”
“Site workers do seem to have immense grips. A lot of the groundworkers I worked with had bone crushing hands.”
