I definitely see myself doing this job
1) for as long as I am able to
2) for as long as I have the desire to
(in other words ..for a long time!)
Once about a time (i.e. the 80’s) personal training wasn’t considered a ‘real job’; it was something you do on the side.
Now-with a more health conscious population and a desire to ‘remain active ‘ the possibility of a career as a personal trainer is a possibility.
Good luck – hope you see yourself doing this for the rest of your life!
