I used to work in a large gym before I decided to go off on my own. Currently I work with people where ever they choose to meet (home, offices, sporting complexes, schools, etc.) and I absolutely love it. All of my clients have been just from word of mouth, and so far it has kept me pretty busy. I also help out in different physical therapy clinics in the area to help trade services as well as continuing to build up a greater knowledge base. This also leads to more referral sources.
Whether you choose to open up a location, or to have a mobile training service, there are going to be different pros and cons. Mobile training gives you the opportunity to pick up clients who are too busy to make their way out to a location, so you going to them is much more convenient. If you are able to line up a schedule where all your clients live pretty close, you can do pretty well because you won’t have any overhead. The downside is when you have clients far apart, then you are losing time of the day you could be training because you are driving. If you have a studio, than you have somewhere that will be more viewable for people to see what it is you offer. The downside is overhead, but once you get busy enough that won’t be as big of a deal and you could also start to rent out space to other trainers.
Overall, I really enjoy being off on my own. Just like Karin said, it doesn’t even feel like work.
