To obtain a biomechanics internship, you must be in your third or fourth year of your undergraduate schooling or a graduate degree program. Your area of study should be in mechanical or biomedical engineering, sports therapy, physical therapy, or a related field. Employers often take recommendations from schools, so you visit the appropriate office at your college or university and ask what you can do to get a letter of recommendation. Fulfilling the duties and responsibilities of a biomechanics internship requires excellent communication skills, the ability to follow instructions, and a passion for the industry. Biomechanics internships often take place over the summer, but some are available throughout the year.
