1. Personal Trainer
An aging baby boomer population eager to invest in longevity, along with a growing concern over childhood obesity, make it a great time to join this expanding field. As a personal trainer, you can visit clients in their homes and work with fitness centers on a contract basis.
Check out the National Federation of Professional Trainers for information about the certification process, insurance, marketing, and more. To make yourself stand out, think about taking extra courses in specialized fields, such as nutrition or Pilates.
