In a five-week cardiorespiratory training program, what should a client’s exercise duration be in week 4 if they began at 60 minutes in week 1?

1. 66 minutes

2. 90 minutes

3. 72 minutes

4. 80 minutes

The correct answer is: 80 minutes

The duration of exercise in a cardiorespiratory training program typically follows a progressive model, often increasing in a systematic manner to allow for adaptation while minimizing the risk of injury. In this case, starting at 60 minutes in the first week provides a baseline for subsequent weeks. In the context of week 4, it is important for the client to continue increasing the duration of their workouts to promote cardiovascular improvements and endurance. A common approach to structured training programs is to enhance the duration by a certain percentage or a fixed increment each week. Assuming a gradual increase over the weeks, such as adding approximately 10% to the previous week’s duration, one can calculate the durations as follows: - Week 1: 60 minutes - Week 2: 66 minutes (adding 10% of 60) - Week 3: 72 minutes (adding 10% of 66) - Week 4: Expected to achieve about 80 minutes (adding 10% or more based on progression strategies). Therefore, reaching 80 minutes in week 4 aligns with the principle of progressive overload, emphasizing the importance of building up endurance over the program's duration. This structured increase is essential for safely promoting improvements in fitness levels without
