“Lack of activity destroys the good condition of every human being, while movement and methodical physical exercise save & preserve it.”

Plato 427-347 BC

Applying the 80/20 Rule to Strength Training

Alistair Ramsay - Monday, January 25, 2010
The 80/20 Principle was discovered in 1897 by the Italian Economist Vilfredo Pareto (1848-1923). His discovery has since been called many names including;

  • The Pareto Principle
  • The Pareto Law
  • The 80/20 Rule
  • The Principle of Least Effort
  • The Principle of Imbalance
What does the 80/20 Principle Imply?

The 80/20 Principle demonstrates that the universe tends to follow unbalanced relationships for example;

  • 20% of Inputs yield 80% of Outputs
  • 20% of Causes lead to 80% of Consequences
  • 20% of Efforts produce 80% of Results
Examples of these unbalanced relationships are all around us;

  • 80% of the wealth is possessed by 20% of the population
  • 20% of products account for 80% of business sales
  • 20% of your clothes will get worn 80% of the time
  • and the list goes on
The ratio 80/20 is used purely to highlight the existence of an imbalance. The actually ratios could be even higher in any given situation e.g. 90/10. In fact they do not need to even add up to 100. It would be quite plausible for a relationship to exist whereby 20% of inputs led to 100% of outputs.

I believe that this same principle can be used to make your strength training routines more efficient and effective. Too many people spend too much time performing inefficient strength training routines. I am talking about the folks who spend an entire session performing 8-10 exercises targetting different areas of the chest. The next day 6 exercises are used to hit the shoulder muscles from every possible angle. The following day the biceps are given a roasting.

Training like this is crazy.  I strongly believe that the vast majority of benefits associated with strength training can be derived from a small % of the exercises.

How is this possible?

By performing multi-joint compound exercises such squats, push ups and pull ups. These exercises simultaneously target multiple muscle groups working across multiple joints. They challenge the body to stabilise certain joints, whilst generating force and moving other joints through full ranges of motion.

If you have a full body strength training program that consists of a squat, a push, a pull and a core exercise you have a really solid program that will allow you to reap 90% + of the benefits associated with strength training. You will get stronger from head to toe, you will up your metabolism and burn fat, your joint strength will increase, your blood pressure will decrease, your body will go from soft and wobbly to hard and firm. On top of all that you will be able to perform your strength workouts in 40 minutes or less. Forget hitting the gym every day to get all your body parts trained by the weeks end, complete waste of time and effort.

Apply the 80/20 principle to your workouts and cut all the exercises which are bringing you little to no extra benefit. This will save you a bucket load of time whilst still reaping all the benefits your hard efforts deserve.
