Atlas stones are large, heavy spheres made of concrete or stone, commonly used in strength competitions. They vary in weight, typically ranging from 100 to 400 pounds, and are designed to test a competitor's strength and technique. The goal is to lift and place the stones onto platforms of varying heights. These stones are named after the mythological figure Atlas, who was said to carry the weight of the heavens on his shoulders. In strength sports, lifting Atlas stones is a key event in competitions like the World's Strongest Man, showcasing the raw power and skill of the athletes.
