As a personal trainer, my rate goes by a sliding scale of $75/hour. My clientele is wealthy and highly educated. As a kinesiotherapist, gerokinesiologist, exercise physiologist, and personal trainer, I also hold various certifications and have a 20+ year background in classical ballet. I have a given rate with institutions hiring me, such as a fitness center and a retirement residence, but wonder what to charge a company with 450 tenants wishing to offer fitness classes as an additional service to its tenants.
One area where you might be able to charge top dollar for group exercise is in a ballet-based class. Classes like balletone and the like are well like and can be charged a higher rate for as they are a specialty.
If you’re going to try and teach a common form of group-exercise, be prepared to be paid the “going rate” for instructors of that format for your area.
My experience is the opposite of yours. I have 22 years in group-exercise and 4 in personal training. I’m highly experienced at group-ex so I’m on the top end of the pay scale at places where I teach it. But where I make the most money is small-group personal training (CrossCore and ViPR). It leverages my greatest skills (group), but in a more profitable setting. I’m an average-paid personal trainer, but I do very well in small group.
That’s why I suggested maybe leveraging off of your ballet skills. For generic classes, unless you’re so good that you’re bringing in clients (get commissions written into your contract!), group exercise is only worth so much to an employer / owner.
