01
Progression means the demand changes.
Human Foundations defines progression as gradually increasing the training demand. If the stimulus never changes, the body has less reason to continue adapting. Progress can come from load, frequency, duration or another relevant training variable.
02
Gradual is different from random.
Adding difficulty without a reason is not the same as progression. The training variable should change because it supports the goal and because the current level has become an appropriate base to build from.
03
Specificity keeps progress connected to the goal.
The body becomes better at what it repeatedly practises. If the goal is to improve a particular movement or physical quality, training that resembles that demand will usually transfer more directly than unrelated work. Other exercises can support the goal, but they do not erase specificity.
04
Reversibility is part of training reality.
Training adaptations are not permanently guaranteed. When training demand is reduced for long enough, qualities such as strength, endurance and flexibility can gradually decline. Continuity matters because adaptation is maintained through continued exposure.
05
More is not the standard.
The ORIGIN standard is quality before intensity. Progression should increase useful capacity, not become a reason to chase heavier numbers, more fatigue or more complexity before the person is ready.
