| So the heavier the concrete,
the more it sinks into the ground, the more of a hulk it takes to pull them. The
resistance is constant from start to finish unlike pulling those heavy wheeled vehicles on
a solid pavement surface as the resistance lessens as the wheels rolls faster from start
to finish. Most strongmen won't try to pull that much concrete on the grass without a dog
sled on video, or in a strongman competition, but those professional football players
train with that much weight with a dog sled on the grass. |
