During a fitness trainer internship, your job is to learn more about supporting the health and wellness of others. As a student, you may participate in a fitness training program, learn more about setting athletic goals for others, and learn how to adapt exercise strategies to account for the unique fitness needs of each client. Some fitness trainer internships focus on specialized areas. For example, you may focus exclusively on helping people learn to sprint faster or perform well in specific sports. Other fitness trainer internships focus on general exercise and wellness at local gyms. The type of internship you can take may impact your career options, so be sure to review your internship opportunities carefully.
