First of all, I am an introvert.
So, I write this article as an insider, not a critic! I'm using the term introvert in the way that the Myers-Briggs Personality Test uses it. It's NOT about whether you're shy or social. Instead, introverts get their energy from quiet time, reflection, and analysis. The opposite personality type is represented by extroverts, who get their energy from being around other people. Again, extroverts may like quiet time (and can even be shy!) but they recharge themselves by socializing.
There are actually 16 personality types. You can take the test here (after you're done reading this article, of course). My full personality type is INTJ:

Anyway, think about the characteristics that make a good group fitness instructor: friendly, charismatic, energetic, motivating, and maybe a little loud? I recently found myself wondering if these are traits that are mastered by extroverts and tougher for introverts to exhibit.
It may be true. Introverts probably have to work harder to keep up their energetic instructor persona than extroverts do. We may also have to work up more courage to interact with our students and other instructors than our socially-minded extrovert peers. Unfortunately, these tendencies can make us seem standoffish or uninterested at the gym or studio, which couldn't be farther from the truth!
Luckily, I think there are also some important benefits to being an Introvert Instructor, including:
You look out for everyone. The front row divas may demand more attention, but as an introvert you're naturally checking on the students in the back and corners, making sure they're engaged and comfortable.
You respect people's personal space. I know some instructors and students love to dance together, but invasion of personal space was a major reason why I hated my first Zumba class (true story!). As an introvert, I know to give students plenty of room.
You plan for everything. Introverts are known for analyzing situations and rehearsing scenarios ahead of time. As an Introvert Instructor, you've probably thought through how your students will react to different songs and routines. You've probably even rehearsed your opening speech at the beginning of class (guilty!).
You seek to bond with your students. Introverts may be overwhelmed by mingling with a group of students all together, but we also love to engage in deeper, one-on-one conversations with individuals. I love chatting with students and getting to know them personally.
Where are the Introverts out there? How do you think being introverted fits (or not) with being a group fitness instructor?
