Today, the treadmill is the most popular piece of fitness equipment, found in homes and health clubs around the world. But where did this great cardiovascular machine come from?
Ancient Roman Tread Mill Crane
The “tread mill” also known as the “tread wheel” was first introduced in the height of the Roman Empire, around the late first century AD. When the Romans found they had a need to lift heavier weight, they incorporated the treadmill, replacing the winch in their cranes. The men would walk within the wheel itself and because the treadmill had a larger diameter, they were able to lift double the weight with half the crew.
