Typically you can train with sledge hammers in two ways: levering, or using them to smash a truck tire, but here’s an innovative feat done by Dennis Rogers, the Grandmaster Strongman. Here Dennis Preacher Curls two loaded-up sledge hammers with a total weight of 82 pounds. 82 pounds doesn’t sound like a lot of weight — and it certainly isn’t for Dennis — but the fact that you have to maintain the crushing strength to keep the hammers in one place while you curl them makes this feat quite impressive.
