In South Florida, economical situation is not in its best shape.
Most clubs are paying about $20. per hour, and that Iif you have a National Certification, if you are not then the pay is lower.
It does generally allows you to be able o workout for free, and some companies give you, access to free workshops. At the beginning of this year I waas making $25. things have gone for the worse. Forget about a raise, how about keeping the job. Good Luck!
