What principle of training involves gradually increasing the demand on the body?

The principle of training that involves gradually increasing the demand on the body is progression. Progression is essential for adaptation, as it encourages the body to make physiological changes when faced with increasing stress or demand, whether through improved strength, endurance, or other fitness capacities. This principle helps prevent plateaus in training and promotes continuous improvement by systematically increasing the intensity, volume, or complexity of workouts over time.

This concept is crucial for ensuring that individuals avoid stagnation in their fitness levels and continue to achieve their goals. Proper progression involves monitoring the body’s responses and adjusting training loads incrementally, allowing for recovery and adaptation, which enhances overall performance and reduces the risk of injury.
