I have worked in a gym and now work as a mobile trainer. I definitely earn more now than I did in a gym. I sell my sessions as a package with payment up front. This benefits both the client and the trainer; the client has to make a commitment an I am assured a certain amount of money. I have been doing this for a few years now, and ave never had a client not renew thir contract.
I have a gym in my home where I train most of my clients.I bought my equipment overtime. I get to write off my equipment and space. I also worked at a gym and they took most of our money for each session. I love the freedom and since I am at home I workout between clients and get stuff done in my house.
Session for session, I make way more training mobile. The personal cost, however, is also way higher in time utilized. Transportation, loading equipment, planning routes in case of road work or traffic.. yadda yadda ya. So, I don’t normally do it. I have a studio and I love it. I train more sessions per day and don’t have nearly the hassel. I do still undertake mobile sessions but they cost… a lot.
