Personally I wouldn’t ask if I get 40, 50 or 60% of the pie.
Id try to make the pie larger, or make more pies- if that makes sense for this question. Personal trainers work with their gyms in a mutually beneficial relationship. If one side doesn’t hold up their side, everyone gets a smaller paycheck.
70% of being a personal trainer is selling yourself. Do that, present good classes and the money will make itself.
I believe it all depends on your own appraisal of what matters to you and how comfortable you feel prospecting.
When I first started, at 24 Hr Fitness, I learned how to prospect. Once you are comfortable and get good at that, then you better look for a club with a good split. I worked at Lifetime fitness, with a very descent split, later I became independent. So, find your way and be happy with it.
I think that it depends. This requires you to take a critical look at a variation on the proverbial question of “big fish in little pond, or little fish in big ocean.” By this I mean that if you’re getting a larger commission, but fewer clients then your ‘bottom-line’ take-home pay may still be smaller than if you were getting more clients at a SLIGHTLY smaller commission. I added the emphasis here to the word “slightly” because you will need to do some rough math here to determine your break-even point at which how many of these additional clients would you need at the lower commission level to make up for the lower commission. Admittedly this will only be your “best guess,” but it’s worth doing this before deciding which path to take.
I hope that this helps!
