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.

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