MMA athlete Mike Bruce, a man who is already well known for demonstrating extraordinary neck strength in his workouts (such as seated neck extensions with plates totalling his bodyweight), performs a strongman feat not seen for over 20 years (bodybuilder-turned-strongman Mike Dayton was also famous for this feat).
