Given the options provided, a good indicator of a questionable exercise video would be:
- Option c: Presents high-intensity exercises after the warm-up.
Explanation:
High-intensity exercises should typically be performed after the warm-up phase in an exercise routine. Starting with high-intensity exercises without a proper warm-up can increase the risk of injuries such as muscle strains. A well-structured exercise video should prioritize safety and gradually increase intensity throughout the workout to prevent injury and promote effectiveness.
By presenting high-intensity exercises immediately after the warm-up, the video may not be following best practices in exercise programming, which could raise questions about its quality and safety for the viewers.
