For me, and one factor with my schedule, it is finding a healthy balance–learning to say “no” and avoiding burnout. I love everything I do, and take on more than I should sometimes. I am finding the time to train my clients, create workshops, and teach classes, but need to create more balance for myself (I just gave up working one day a week so I’m on the right track). I’m a better trainer when I find balance. (Although it does help to have an outlet in fitness other than just training–and teaching classes/workshops is a wonderful way to keep it interesting)
Another challenge in the fitness industry is simply making a brand name for yourself and distinguishing yourself from others. It helps to have a clear training philosophy and a mission statement. When I get discouraged, I always fall back on what I stand for and what my purpose in this industry is–and that always gets me back on track and refreshed.
I have an in-home business and teach/train at a local Rec center, so for me it is a great mix (and I don’t have any overhead or great outside expenses).
Others will have different challenges, but those are mine!
