According to the Transtheoretical Model of Behaviour Change, a person who irregularly exercises is likely in what stage?

In the Transtheoretical Model of Behaviour Change, the Preparation stage is characterized by individuals who intend to take action and have begun to make small changes toward their goal. A person who is exercising irregularly falls into this category because they have recognized the need for change and are actively engaging in behavior, albeit inconsistently. This stage reflects their commitment to preparing for more consistent exercise by potentially developing a plan while still needing further motivation or structure to establish a regular routine.

The other stages in the model highlight distinct levels of readiness for change, such as the Action stage, where individuals are actively engaged in consistent behavior change, or the Contemplation stage, where they are considering change but have not yet taken steps. Precontemplation represents a lack of awareness or intention to change at all. Therefore, the irregularity in exercising confirms that the individual is in the Preparation stage, where they are getting ready to adopt a more structured and consistent exercise routine.
