Innovation Theory: Weightlifting Equipment as a Case Study

Introduction to Innovation

In general, innovation refers to changes resulting from conceptual evolution. In some respects, innovation refers to and is primarily a function of changes in knowledge and the application of that knowledge to existing conceptual frameworks. In other respects, innovation refers to and is a function of entirely new conceptual frameworks.

Likewise, innovation can relate primarily to tangible products, to processes, or to new uses and applications of products. It can also result from new combinations of multiple different products and/or processes — or from applying existing tangible products and processes in different ways that generate new applications or capabilities exceeding what those individual products or processes were capable of independently.

Different theorists and analysts may define the specific elements and interrelated characteristics of innovation differently or in different terminology, but in principle those descriptions and characterizations refer to the same underlying concepts and relationships. Similarly, different perspectives may emphasize or analyze different aspects of innovation — for example, Drucker (1985) focuses mainly on innovations themselves and on the manner in which innovations affect their adopters.

Historical Example: Early Weightlifting Equipment

Innovation analyses can also involve understanding larger patterns of adoption, such as those reflected through rates of adoption or the specific psychological factors responsible for particular patterns and trends, as outlined in Types and Patterns of Innovation. Regardless of the particular focus of analytical attention, the study of innovation is best understood and described through historical examples and theoretical concepts of the process by which purposeful changes are incorporated into human life.

In the early 20th century, weightlifting equipment consisted of cast iron dumbbells and an innovation that allowed exercisers to create different levels of resistance on a single hand-held bar by means of interchangeable weighted plates that could be easily attached to or detached from the bar. Before this innovation, weightlifters had to have access to a much larger range of prefabricated weights. The innovation of the holed weight plate allowed exercisers to increase the resistance on a single bar incrementally.

In terms used by Drucker (1985) to describe this evolution, the transition from fixed weights to weight sets using holed plates and an adjustable bar would be considered an example of several different elements of innovation attributable to a simple realization made by a single person. This simplicity is a hallmark of Drucker's definition of innovation. More specifically, the evolution of holed weight plate sets was a function of incongruity, because it solved the incongruity between what weightlifters would have preferred to be able to do with weights — that is, use many different weights for very different exercises — and what the available technology required to achieve that objective, namely purchasing and housing a large number of weights in many different sizes.

In the terminology of Types and Patterns of Innovation, the transition from fixed weights to holed weight plate sets would be described as an incremental, architectural, competence-enhancing product innovation. That is because the addition of holes to weight plates, which allowed them to be affixed individually and in different combinations to a single hand-held bar, was a relatively minor rather than radical change. It changed the way the individual components — weights and bars — functioned together, rather than altering only one component or the other individually. Moreover, it greatly enhanced the usefulness of weightlifting bars without rendering fixed dumbbells obsolete in the process.

Jack LaLane and the Radical Transformation of Resistance Training

In the middle of the 20th century, a single exercise enthusiast who would later become nationally known as Jack LaLane single-handedly revolutionized weightlifting by virtue of an original inspiration that Drucker would likely regard as attributable to genius and as functions of process needs, industry and market changes, and new knowledge. Specifically, Jack LaLane was probably the first modern professional fitness trainer in American history. As a young man, he was a fitness enthusiast who, before becoming famous, earned a living teaching others how to build their bodies through resistance training.

At the time, there were very few weightlifting gyms, and those that existed were not particularly welcoming to novices or recreational users. They were dingy, dirty, and frequented more by competitive athletes such as boxers and wrestlers than by ordinary people hoping to change the way they looked. Jack LaLane recognized that there was a demand for an accessible gym, so he built his own personal fitness studio where he trained his clients.

He realized that the most effective resistance training could be accomplished if there were some way to change the direction of gravity from straight up and down to adjustable angles. He recognized this was particularly important to his clients because novices lacked the coordination and strength to exercise efficiently and safely with hand-held "free" weights that traveled through three-dimensional space.

LaLane's knowledge of the specific needs of his clients led him to create a multiple-pulley system to change the direction of resistance so that exercises could be performed at many different angles rather than just in the vertical plane. He also created a plate-loading system that simplified, sped up, and made the process of changing weight much safer. Instead of manually adding and removing weighted units to a fixed bar, LaLane created a weight stack with a hole down the center and a locking-pin system to enable the selection of any number of plates in the stack through the simple adjustment of the pin.

Conclusion

Furthermore, the introduction of plate-loaded weightlifting machines represented the beginning of a technological trajectory that would inspire decades of subsequent evolution, incremental innovation, and refinement. Within the commercial gym application, LaLane's plate-loaded machines would also be considered a discontinuous technology because they relegated free-weight and traditional plate-loaded equipment to private home use and to hardcore gyms almost exclusively.

Unfortunately, as innovative as LaLane was technologically, he was not equally sophisticated in business: he failed to patent his revolutionary design. Nevertheless, his genius still serves to illustrate the fundamental concepts of human innovation. The evolution of weightlifting equipment — from fixed iron weights, to holed plate sets, to LaLane's pulley-and-pin machines — demonstrates how the same real-world development can be interpreted through multiple theoretical frameworks, and how both incremental and radical innovations can reshape an entire industry over time.
