At The U of Strength, we don’t call it strength training. We call it force development. That distinction matters.
Strength is certainly important, but simply increasing the amount of weight an athlete can lift does not tell us the whole story. Sport requires athletes to interact with forces constantly. They must accept force, produce force, transmit force, redirect force, and express force, often within fractions of a second and under constantly changing conditions. The weight room can help build the physical resources required to solve these problems, but those resources are only part of the process. The question isn’t simply: How strong is the athlete? A more useful question is: How much force does the athlete possess, and how effectively can they express it when the environment demands it? This leads us to an important distinction between force potential and force expression. Force Potential vs. Force Expression We view force development through two interconnected lenses. 1. Force Potential Force potential represents the athlete’s capacity to generate force. It can be influenced by factors such as muscular capacity, neural output, coordination, tissue qualities, training experience, and the athlete’s ability to organize their body against resistance. In simple terms: How much force does the athlete have available? The weight room provides us with an environment where we can intentionally expand this capacity. But possessing force is different from being able to use it. 2. Force Expression Force expression is the athlete’s ability to access and apply their available force within the time, space, and informational constraints of movement. Sport rarely provides athletes with unlimited preparation time. They must accelerate when space appears. Decelerate when an opponent changes direction. Reorganize their body after contact. Jump from imperfect positions. Redirect force when their original movement solution is no longer available. The athlete may possess tremendous force potential, but the sporting environment determines how much of that potential can actually be expressed. This is why weight room numbers alone cannot define athletic performance. Force potential is what the athlete possesses. Force expression is what the athlete can access when the situation demands it. You Can’t Express What You Don’t Possess While force expression matters tremendously, force potential cannot be ignored. There is a simple relationship: You can’t express force you don’t possess. Developing greater physical capacities expands the athlete’s potential movement toolbox. This is particularly important throughout long-term athletic development. Resistance training can help athletes develop greater physical capacity, improve coordination under load, increase tolerance to force, and provide additional movement options. But the objective isn’t simply to make the athlete stronger. The objective is to develop physical resources that can eventually become useful outside the weight room. For that reason, we organize our force potential development around three interconnected qualities: Acceptance. Production. Transmission. 1. Force Acceptance: Yielding Force acceptance refers to the athlete’s ability to receive, manage, and organize force entering the system. Think about the demands of sport: Landing from a jump. Decelerating from high speed. Lowering the center of mass before changing direction. Managing contact from an opponent. Transitioning from one movement solution into another. The athlete isn’t simply “absorbing” force. They are actively organizing themselves around the forces created by the environment. We often use yielding strategies to develop this capacity. These may include different landing variations, “fake” throws, eccentric actions, deceleration problems, and other environments that expose athletes to different magnitudes, directions, and durations of force. The goal isn’t to create one perfect position. It is to expand the athlete’s ability to successfully manage force across many situations. 2. Force Production: Overcoming Force production is probably what most people associate with traditional strength training. The athlete must generate enough force to overcome an external resistance. Squatting. Pressing. Pulling. Jumping.. These are all examples of force production. But simply increasing load is not the only way to develop this quality. We can manipulate resistance, range of motion, starting position, velocity, intent, stance, and many other constraints to change the problem presented to the athlete. This is where individualization becomes important. The athlete shouldn’t have to fit the exercise. The exercise should fit the athlete. Instead of forcing every athlete through identical exercises and progressions, we can manipulate the training environment based on what the athlete needs. The exercise is simply a vehicle. The adaptation is the destination. 3. Force Transmission: Elasticity Force does not simply need to be accepted or produced. It also needs to move efficiently through the system. This is where force transmission becomes important. We associate transmission with elasticity, the athlete’s ability to rapidly manage and transfer force through interconnected segments of the body. Sprinting provides a simple example. At high speeds, athletes do not have unlimited time to produce force against the ground. Ground contact opportunities become increasingly brief. The athlete must arrive prepared to interact with the ground, manage the incoming forces, and rapidly redirect those forces into the next action. This requires more than strength. It requires timing. Rhythm. Coordination. Pretensioning. Stiffness where necessary. Compliance where necessary. And the ability to organize those qualities at speed. Elastic training therefore becomes another important piece of the force development puzzle. These Qualities Don’t Exist in Isolation Acceptance, production, and transmission are useful categories for organizing training, but the human body doesn’t experience them as isolated qualities. Every athletic action contains some interaction between them. An athlete sprinting must accept force when the foot contacts the ground, transmit force through the system, and produce force to project into the next step. An athlete changing direction must manage incoming momentum, reorganize their body, and produce force into a new direction. An athlete landing from a jump must manage force before transitioning into whatever action comes next. The goal of training isn’t to create athletes who are great at isolated categories. The goal is to provide them with physical resources they can integrate into adaptable movement solutions. Bridging Force Potential & Force Expression This is where athletic development becomes more interesting. The weight room can increase force potential. But sport asks athletes to express that potential under very different conditions. Sport contains uncertainty. Opponents. Teammates. Time pressure. Limited space. Changing visual information. Fatigue. Contact. Emotional pressure. No perfectly controlled weight room environment can completely recreate those demands, and it shouldn’t try to. Instead, we can view training as a continuum. On one side, we develop the athlete’s physical resources. On the other, we create environments that require athletes to explore how those resources can be expressed. Resistance training, sprinting, jumping, landing activities, and small sided games can all play different roles within that process. The goal is not to make everything look like the sport. The goal is to build capacity and create opportunities for that capacity to become usable. Develop the Human, Not the Exercise This is ultimately why we prefer the term force development. Strength training can unintentionally become centered around exercises. What is your squat? What is your bench? What is your deadlift? How much weight did you add? Those numbers can provide useful information, but they are not the athlete. At The U of Strength, we’re interested in the larger system. Can the athlete accept force? Can they produce it? Can they transmit it? Can they redirect it? Can they access it quickly? Can they organize it from different positions? And ultimately: Can they express it when the environment demands it? The weight room should expand the athlete’s movement possibilities, not restrict them to a collection of exercises. Because the goal isn’t to create better lifters. The goal is to develop athletes with a larger toolbox of force solutions available when sport asks them to solve a problem.
