A system of vertically arranged metal plates, each weighing a specific amount, provides resistance for strength training exercises on a cable-based exercise apparatus. This resistance system allows users to select a desired load by inserting a pin into the stack, engaging the corresponding plates. For example, selecting a weight of 50 pounds engages all plates totaling that weight.
This type of resistance offers several advantages over free weights, including smoother movements due to the cable and pulley system, a reduced risk of injury due to controlled movements, and a wider range of motion. The development of this system revolutionized resistance training by providing a safer and more versatile method for individuals of all fitness levels. Its adjustable nature allows for precise load increments, facilitating progressive overload and targeted muscle development.
