Mjolnir
Thor's enchanted hammer, forged from a dying star/Mythical & Fictional

According to Marvel canon, it was forged from Uru metal in the heart of a dying star and weighs 42.3 pounds (19.1 kg). The handle is 44.5 centimeters long, wrapped in leather. It can only be lifted by those deemed worthy, which conveniently excludes everyone except Thor and a select few, making it the universe's most exclusive gym equipment.
