I wouldn’t necessarily shy away from what is becoming “trendy” in fitness, as long as it is a safe and effective form of exercise for your particular area of interest. Providing something that people are talking about and looking for can be very helpful while you begin to build your business. Essentially, this can easily help you create a client base. Yet, with the “trend’ there still needs to be knowledge, education and the ability to apply what you learn (professionalism that sets you apart). The “trend” might get you clients, but it’s YOU that’s going to keep them coming back. Also, you might want to look around and see what’s not being offered in your community – “fill a need” so to speak. 🙂 Good Luck!
