Fitness instructors have to be at once coach and performer. Also, the ability to adapt to the group being taught is essential. Competency with biomechanics, exercise prescription, and special populations also improves the effectiveness of a given professional. I have been teaching for 20 years and write/edit for a large fitness company. Outstanding music is important, but when you instruct YOU are the product. MANIA conventions offer a lot of wonderful continuing education options. Go to www.scwfitness.com to find out more. If you are new and not experienced with choreography, there are pre-scripted options that are credible...you learn the release and safety, effectiveness, and soundtrack are built in. Go to www.lesmills.com for more information about that option.
