5 minutes 17 seconds to snap this piece of steel regulated by David Horne at THE WORLD OF GRIP.
I was a medalist in the STEEL SHREDDER international competition (My best bar being the 12mm X 18" in 15 minutes)
BW 85kg.
This not just about having a strong grip...The engine, work ethic and general robustness will be tested. Enjoy and ask if you have any questions for your own snaps.
