What is one of the key principles of training that focuses on individual capabilities?

The key principle of training that emphasizes individual capabilities is centered around individual differences. This principle recognizes that each person has unique characteristics, including their genetic background, fitness level, psychological traits, and prior exercise experience. Because of these differences, training programs should be tailored to accommodate individual needs, strengths, and limitations. This personalization ensures that each individual can achieve optimal results while minimizing the risk of injury and maximizing enjoyment in their fitness journey.

For instance, a program designed for someone with a strong athletic background may not be suitable for a beginner. By focusing on individual differences, trainers can create more effective and sustainable training plans that recognize and respect the unique profiles of their clients.
