Coming up with new material and leading group fitness classes. Accounting for clients with chronic disease, injury, and/or other special populations. Being personable and engaging in communication with clientele throughout sessions.
I would say that my greatest accomplishment would be that I was able to get comfortable leading classes in a group setting.
Not everyone learns the same. Some people will work harder than others. Always check on your clients (if they miss a day, ask them if everything is okay).
What advice would you give?
Work on your verbal communication skills early. Find a job in a fitness setting prior to your internship. Don't get too into your head, let everything flow when leading. Build relationships early.
