What is the definition of Fitness Weapon?

A fitness weapon is a rather absurdly outlandish term that refers to any piece of exercise equipment or workout routine that's so over-the-top, it's like a gym selfie stick gone wild. Imagine a kettlebell that's so heavy, it's like trying to lift a small, metallic elephant. Or picture a rowing machine that looks like it was designed by a mad scientist in a sci-fi movie - but with real muscles.
