In the action phase of adopting a new exercise program, which statement best describes the expected behavior?

• A. Researchers workouts without implementing them
• B. Continues to plan without committing to a schedule
• C. Actively perform the new exercise behaviors and adhere to a plan
• D. Relapses immediately to old habits

Answer: (C)

In the action phase, change is concrete and observable: the person actively performs the new exercise behaviors and follows a structured plan. This stage is about putting the new routine into practice, committing to regular workouts, and sticking to the schedule despite obstacles.

That’s why the statement describing actively performing the new exercise behaviors and adhering to a plan fits best. It captures the shift from thinking or planning to actually doing, which is the hallmark of this phase.

Why the other ideas don’t fit: researching workouts without implementing them reflects planning or evaluation, not action; continuing to plan without a scheduled commitment shows preparation, not actual behavior change; and relapsing back to old habits indicates a setback, not sustained action.
