11 High-Paying Blue Collar Jobs with Mike Rowe

Personal Trainer

Median annual salary: $53,056

We put this on the dirty jobs list because it involves other people's sweat and occasionally some...um...heavy lifting. You also have to work hard to keep yourself in shape at all times, and you spend most of your time hanging around a locker room at the gym.

Whether you're affiliated with a gym or working independently, some states require personal training certification.
