The 80/20 Rule

The 80/20 Rule, is a concept that claims that roughly 80% of the effects come from 20% of the causes. In the context of CrossFit and fitness, the 80/20 Rule can be a powerful tool for optimizing training and achieving maximum results. This principle suggests that a significant portion of your progress is driven by a small number of key factors, and understanding and focusing on these factors can lead to more efficient and effective training.


One of the key applications of the 80/20 Rule in fitness is in identifying the most impactful exercises or movements that contribute the most to overall strength and conditioning. Rather than spreading efforts evenly across a wide range of exercises, the principle encourages individuals to identify the critical few movements that yield the greatest results. This involves focusing on compound exercises that engage multiple muscle groups simultaneously, providing a more comprehensive and efficient workout.

Fitness has ten adaptions: Strength, Stamina, Cardio-Respiratory Endurance, Flexibility, Power, Speed, Coordination, Accuracy, Agility and Balance. If we follow the 80/20 rule, it makes sense that two of the these will give the greatest results. The two that do this are: Power and Speed. To get better results we need to develop our power and speed. Better performance in power and speed gives maximum results in the other eight adaptions. In CrossFit we are always pursuing speed and power, knowing it will give us the most bang for buck.  

The movements that increase power and strength involve moving large loads, long distances over a short period of time. Squats, deadlifts, presses and pullups make up the foundational 20 percent of movements in CrossFit.  Of course, there are variations of these movements. This means that if we have weaknesses in these movements, working on our weaknesses is vital to allow us to improve our power and speed for optimum results. The result of focussing on these vital movements and improving our weaknesses in them is that we improve performance in all other movements and the functional movements we use generally in our lives.

Furthermore, the 80/20 Rule can be applied to nutrition and diet. Instead of adhering to complex and restrictive diets, individuals can identify the few dietary changes that will have the most significant impact on their health and fitness goals. This might involve emphasizing nutrient-dense foods, managing portion sizes, and addressing specific nutritional deficiencies.

On a personal development level, understanding the 80/20 Rule can lead to a more focused and intentional approach to goal setting. Rather than trying to address every aspect of life simultaneously, individuals can pinpoint the critical few goals that will have the most profound impact on their overall well-being and success.

The 80/20 Rule emphasises the disproportionate impact of a small number of factors on overall outcomes. In the context of CrossFit and fitness, it encourages a targeted and strategic approach to training and nutrition, focusing on the key elements that drive the most significant results. This principle extends beyond the gym, offering valuable insights into time management, productivity, and personal development, ultimately guiding individuals toward a more efficient and impactful life.
