Based on your responses to our comments so far, I would say that you have to find out the things that will make you stand out from all the other trainers. So how are you going to market yourself so that clients will be drawn to you? What makes you unique?
I was at a conference recently where the speaker told us that if we wanted to find out what makes us unique, we have to know what our character is like. There is no point trying to draw in every client out there (if fact, even with the amount of people in the industry, we should still be at a point where competition shouldn’t really be an issue). She advise that we go back as far as looking at our old report cards from our days in school and see what our teachers have said about us. We’ll often find very similar comments year after year (hopefully there are positive ones). We want to find keywords that are frequently used to describe us. Those are the things that you use to describe yourself to others when you market yourself.
Likewise, you can always observe your circle of friends. Find the 3 people you closely hangout with. Have them try to describe you, or try to observe their behaviour. The people we closely hang around usually have the characteristics that are very close to us.
Afterwards, you have to be able to know who you want to train. While trainers should be flexible to train a variety of clientele, we know that we don’t want to deal with all sorts. For example, in my gym, I get all types of clients and I’ve work with them all (youth, seniors, pregnant women, sport athlete, weight loss client, absolute beginners, post-rehab, body builders, etc). Despite this, I find myself being drawn most to the sport athletes, absolute beginners, and those requiring corrective exercise and would prefer these clients over all others.
So, not only do you need to know the demographs in your area, you need to identify for yourself who you want to work with. That will help you avoid so many headaches in the future. Hope that helps you find your way.
