The salary of a fitness instructor consists of three parts, the first is the basic salary, the second is the class fee, and the third is the performance commission. The higher your performance, the higher your salary income, and the performance commission is based on whether your class sales are smooth, so sales is an indispensable ability of a fitness instructor!
