One thing about strongman work, it's easy to relate to real-world strength. A 500-pound deadlift or a 200-pound overhead press is impressive, but unless you lift, it's hard to fathom what that means. Watch a guy drag a truck, or lift a car, or pick up a log and press it...you have some idea of what he could do outside of training.
Case in point, Rob pressing a dishwasher overhead. No, seriously.
One can only hope that he took out any breakables first. If you try this at home, I'd also advise not telling your significant other you're pressing the appliances overhead . . .
