I’ve done both as well. It has been much more lucrative for me at a gym/club, I can fill my schedule up easily without as many gaps and of course no drive time lost. And like others mentioned the club fills up some gaps in my schedule with new clients too! Alsom, unless you’re doing in home training for a club or you’re in business for yourself already you not only have to figure in cost of gas but liability insurance as well. The exception for me has been mobile group circuit training. I love doing that and if a group of 8 or more pay for a full month of group training it’s worth my time to go to them.
Hope you find the best fit for you!
Transporting equipment is inconvenient and can add significant cost for equipment needed to train various clients compared to a gym which will most likely have all the equipment you need.
But mobile training is more lucrative than working in a gym as well as being able to set prices based on client income compared to fixed rates which could turn potential clients away in the gym.
I make more money being self-employed as personal fitness trainer. It’s easier to be flexible with clients who have different level of income. I rather receive $15-20 rather than nothing at all. Some of my clients have lower income afford to pay for $50-100 per session. It’s more important to help enhance the quality of life for more people rather than less people.
