Name an everyday example (for example in a workout routine) of this principle The "Principle of effective training loads"

[Context:]
This principle assumes that the training stimulus must exceed a certain intensity threshold in order to trigger an adaptation response.
in order to trigger an adaptation reaction at all (to be effective in training).
Biological background is the so-called stimulus level rule, according to which, with regard to functional and
morphological adaptation changes are subdivided as follows.
- subliminal
o below the effective stimulus threshold -> remain ineffective
- suprathreshold weak
o maintain the functional level
- suprathreshold strong
o (= optimal) trigger physiological and anatomical changes
- too strong stimuli
o damage the function
The threshold value of the load stimulus depends on the athlete's performance status.
