Answer:
A healthy exercise routine includes tried and true injury-prevention activities: warming up, stretching, and drinking plenty of water.

The clause “A healthy exercise routine includes tried and true injury-prevention activities” is an independent clause because it can stand on its own. The information that follows lists the activities. Therefore, the use of the colon is correct.
