Final answer:
Examples of unhealthy progressions include decreasing intensity of workouts, decreasing running time too quickly, and doubling the intensity of a workout daily.
Step-by-step explanation:
The three examples of an unhealthy progression are:
- Decreasing the intensity of a workout by 50% each day: This is an unhealthy progression because reducing the intensity of a workout too quickly can lead to a decrease in fitness and limit progress.
- Decreasing the time it takes to run 5K by 30 seconds each week: While improving one's running time is generally positive, decreasing the time too rapidly can put excessive strain on the body and increase the risk of injury.
- Doubling the intensity of a workout each day: Increasing the intensity of a workout too quickly can overload the body, leading to exhaustion, muscle soreness, and potentially even injuries.
