I agree with Karin. I specialize in working with female athletes on strength and conditioning and injury prevention. I’ve taken special training in this area and am certified as such. However, I started my career as a general personal trainer and to this day still LOVE working with clients of all types and with differing fitness goals. To my mind, to “specialize” is to have a special interest in, to have special training in, and to devote a significant part of your practice to… I analogize this to the medical profession. For example an oncologist may have a large portion of her practice dedicated to a certain cancer type, but at the same time see patients with other types of growths. Or a general surgeon… you get the idea.
I love my work with female athletes, and in general women’s health and fitness, but I have seen plenty of male clients, and helped them achieve a wide-variety of fitness goals (e.g. a Marine pass his fitness test, an older male client continue post-rehab work after back surgery, a teen-aged hockey player etc). While I love my “specialty” work, I also enjoy variety, and that’s one of the reasons I chose this profession.
