What is the recommended progression for aerobic exercise duration for a client starting at 15 minutes per session?

The recommended progression for aerobic exercise duration is often based on principles of gradual increase to promote safety and effectiveness. Starting at 15 minutes per session, a progression of increasing by 5 minutes per week allows clients to adapt to the exercise intensity and duration without risking injury or excessive fatigue.

This incremental approach is beneficial as it provides enough time for the client's body to adjust to the increased demands of aerobic activity, improving cardiovascular fitness and endurance gradually. It accommodates the physiological adaptations that occur as a result of regular exercise and helps prevent any potential setbacks due to overexertion.

Progressing by larger increments, such as 10, 15, or 25 minutes per week, may overwhelm a beginner and lead to a higher risk of injury or burnout. Therefore, the 5-minute increase is practical, sustainable, and aligns with guidelines emphasizing a gradual approach to increasing exercise duration, especially for those starting at a lower fitness level.
