If you are enthusiastic about fitness and think you might be good at leading a group through strenuous exercises and activities, you may want to consider a path to become an aerobics trainer. You may not need any specific level of education in order to become an aerobics trainer, but it is a good idea to complete at least a high school education, if not some college coursework, to improve your chances of finding employment. You will also need to get CPR and first aid certification, as these are likely to be required by any employer.
Once you have such certification, it will be important to determine which types of aerobics interest you. It helps to narrow your focus if you want to become an aerobics trainer, though this doesn't preclude you from choosing several activities in which to specialize. Take some aerobics courses at a local gym or fitness center to gauge your interest in each; throughout, be sure to take note of how the trainer runs the class, gives instructions, and otherwise interacts with participants. Make a mental list of what techniques seem to work well and which ones seem to need improvement. Such observations will help you improve your skills once you become an aerobics trainer.
Many employers will require that you earn certification from a respected and recognized exercise organization. Do some research to figure out which organizations are respected and recognized in your region of the world; there may be more than one, so read a few job descriptions to find out which ones most employers are looking for. Take part in the training courses and pass the certification exams. Remember that this process can take quite a bit of time, and you will need to invest your money into earning such certificates if you want to become an aerobics trainer.
Write a strong resume that outlines your past education, your experience, and your training. This document will give employers a good idea as to how prepared you are for the job. Whenever possible, get recommendations from people who have received aerobics instruction from you in the past; if you have not instructed before, consider doing some volunteer training at gyms, fitness centers, recreation centers, or other community facilities to help build your credentials. This is also a good opportunity to hone your training techniques and recognize which habits and practices work well and which ones don't.
