[Content Update]: Improve Course Cards Content for Better Engagement

[akshay0611]

Problem:
The current course cards contain generic placeholder text that lacks engagement and fails to effectively communicate the unique value of each fitness or nutrition course.

Proposed Solution:

• Rewrite the content of <h3 class="h3 card-title"> and alt attributes to make them more engaging, relevant, and aligned with the goals of a fitness-focused website.
• Highlight the benefits and features of each course to attract potential users.

Expected Outcome:
Course cards that effectively communicate the strengths of each offering and encourage visitors to explore further.
