With over 30 years in the industry you feel that I should just be addressing one niche of fitness. That would drive me up the walls. You want to know my “niche”? I can meet with almost any client and determine a safe, effective, and enjoyable program for virtually any need they should have. About 90 percent of the time, clients come to me for a specific issue or focus and find out that there is a completely unnoticed issue that has been holding them back from achieving their goals. My “niche” is striving to gain a comprehensive understanding of human movement, health, and wellness (including mental and spiritual). I spend at least one hour a day learning something new and one hour a day reviewing something that I want to make part of my skills and abilities. If you are looking for a fitness instructor with a specific set of skills and abilities that they feel very confident in being able to bring to your program, ask them about it. I would more concerned with a trainer who only feels confident in working with only one type of client. How little experience that type of trainer must have to be so restricted in scope. In some markets, there is enough need to be able to “specialize”. But why? Why be stagnant? Why not grow?
