Questions: Which is the MINIMUM amount of time a client should be able to perform steady-state cardiorespiratory exercise at a rating of perceived exertion of 3 to 4 before progressing to Fitness Training? 5 minutes 15 minutes 20 minutes 10 minutes

The answer is 20 minutes.

Explanation for each option:

1. 5 minutes: This duration is too short to establish a steady-state cardiorespiratory exercise. It does not provide sufficient time for the body to adapt to the exercise intensity and achieve a steady state.

2. 15 minutes: While this is a more reasonable duration, it is still on the lower end of the spectrum for ensuring that the client can maintain a steady-state exercise at the given perceived exertion level.

3. 20 minutes: This is the minimum recommended duration for a client to perform steady-state cardiorespiratory exercise at a rating of perceived exertion of 3 to 4 before progressing to Fitness Training. It allows enough time for the body to adapt and maintain a steady state, ensuring that the client has built a sufficient aerobic base.

4. 10 minutes: Similar to 5 minutes, this duration is also too short to ensure that the client can maintain a steady-state exercise at the given perceived exertion level.

Summary: The minimum amount of time a client should be able to perform steady-state cardiorespiratory exercise at a rating of perceived exertion of 3 to 4 before progressing to Fitness Training is 20 minutes. This duration ensures that the client has developed an adequate aerobic base and can maintain the exercise intensity consistently.
