A gym cable, in the fitness context, refers to the high-strength, flexible steel cable that is the core component of cable machines, functional trainers, and pulleys found in gyms. These cables are designed to transmit force from a weight stack to the user via a handle or attachment, providing consistent, smooth resistance throughout an exercise's entire range of motion.

Unlike free weights, which rely on gravity for vertical resistance, cable systems offer versatile vector resistance. This means the force can be applied horizontally, diagonally, or vertically, allowing for a much wider variety of movements that target stabilizer muscles and mimic real-world activities. The cable itself is typically coated with a durable polymer like nylon or vinyl to protect it from fraying, reduce noise, and ensure smooth operation over pulleys.

The key to their function is the pulley system. As the user pulls the handle, the cable glides over these pulleys, redirecting the force from the weighted stack. This creates a consistent, "unfree" weight that challenges muscles differently. Their versatility makes them ideal for exercises like cable cross-overs, triceps push-downs, wood chops, and rotational moves, offering both isolation and compound movement options in a controlled manner. Regular maintenance and inspection for fraying are essential for safety.
