I think that becoming a personal trainer is a rewarding career. Becoming a personal trainer does require receiving personal trainer certifications but I think that it is well worth it because you are helping people achieve a healthier lifestyle that also includes looking and feeling better.
Some people really make a transformation that is inspiring and personal trainers get to see these things happening all of the time. I know that a lot of personal trainers start off working in a gym and when they start to learn the business they strike out on their own.
Personal trainers have the flexibility to schedule their work before a client starts work or when a client gets off from work. They can even schedule lunchtime workouts. They earn a high hourly wage that allows them to have a lot of time off if they choose.
