Physical inactivity --> low inhibitory control --> cascade of body reactions.

Many people struggle with behavior change, not due to lack of knowledge, but because they:

• Lack the psychophysiological capacity to cope and self-regulate under stress.

Confidence gained from mastering physical stress shifts primary and secondary appraisal of future challenges (e.g., “I can handle this”).

Promotes more adaptive coping responses over time.

Physiological changes (e.g., HRV) serve as feedback for mastery (i.e., "my body can handle this"), enhancing perceived self-efficacy.

Changes in biological stress systems reinforce positive reappraisal patterns in non-exercise contexts.

As the body learns to stay regulated under stress, the mind becomes more likely to appraise future stressors as manageable.

If initial sessions are too difficult, participants may feel incapable, reducing efficacy and increasing threat appraisal.

Acute stress response during exercise may feel overwhelming, especially in untrained individuals.
