Dogman Sledgehammer Challenge 1hour 20kg

Stef of The Dogman Kettlebell Club attempted the insane 1 hr Sledgehammer test with the 20kg hammer on monday.

The result - 528 strikes

Crazy!!

Equipment needed:
20kg Sledge Hammer
1 Large Tyre
Grip and Lungs of Steel

Other requirements:
To be mentally unstable is a bonus

Other Hammer Superheroes to have attempted this test of strength and willpower are Jon Bruney and John Brookfield

John Brookfield achieved 27-30 strikes per minute with a 23kg Hammer.
Stef's cadence was 1 strike every 6-7 secs (incredible considering he weighs 69kg)

Maybe this will be a challenge of mine soon!
