Which statement best reflects the lesson's guidance about intensity and volume for someone who currently does no exercise?

• A. Begin with any small amount of activity and progress gradually; some exercise is better than none, and increases in frequency, intensity, or duration over time can enhance benefits while minimizing injury risk when done progressively.
• B. Avoid any activity until you can commit to performing the full PAG targets immediately, because partial efforts provide no health benefit.
• C. Only perform stretching for the first six months and then abruptly transition to vigorous training to ensure safe adaptation.
• D. Start at high intensity to ‘get it over with’ and then drop to no activity, because intensity matters so much that consistency is less important.
