I'm thinking of becoming a personal training do they make good money?

Answer 1

Here's what the US Dept of Labor has to say:

"Median annual earnings of personal trainers and group exercise instructors in May 2004 were $25,470. The middle 50 percent earned between $17,380 and $40,030. The bottom 10 percent earned less than $14,530 while the top 10 percent earned $55,560 or more. Earnings of successful self-employed personal trainers can be much higher."

Hope that helps!
