Personal Training at the Gym
Many professional gyms have a service where you can hire a personal trainer to work with you one-on-one to help you meet your fitness goals. I think the university gym should offer a similar personal training service for students. Working with a trainer to develop your own exercise program would help motivate students who want to start exercising but are having trouble getting started. Also, wouldn’t it be a great idea to hire students who are studying sports medicine to work as trainers? Their services would be inexpensive and it would give them good experience working in the fitness industry.

Evergreen Content
In order to increase traffic and draw more visitors to their Web sites, some companies publish informational articles related to the products they sell. The content of these articles, called evergreen content, is designed to be of continual interest to readers. Just as evergreen trees grow year-round, evergreen content is created to be perpetually relevant and useful. Unlike some forms of online content, such as news articles, which become dated quickly, evergreen content focuses on topics that have no expiration date. Therefore, by producing content that remains relevant regardless of passing time, companies can attract more visitors to their Web sites and ultimately increase sales.
Explain how the example from the professor’s lecture illustrates the concept of evergreen content.
Task4
