The personal training industry is a multi billion dollar one where trainers come and they help you out. Millions of people around the world have used a personal trainer at some point- including me!
But here is the thing: if you are using them in order to bring discipline and health in your life, that is fine. But if you are doing it in order to make yourself look more presentable and professional in your career, there is a much easier way to do it. And that is to use a public speaking trainer. Such a little amount of people use speaking trainers as compared to personal exercise trainers.
Using a personal trainer to enhance your career would not be of much help as you would be facing your colleagues fully clothed and many of your competitors may be in much better shape than you. However, most of your competitors will be awful or boring speakers. Which is hiring a personal trainer to improve your speaking is a much more rewarding experience.
A personal trainer may help you for a little while but once they leave, you may end up right where you started without them enforcing discipline upon you. A good speaking trainer, however, endows you with teachings that will last a lifetime. They will help you master the art of telling a story. This is not to say that you should never hire a personal trainer for your health. What i am suggesting is that if you are going to hire a personal trainer for your body, why not hire a speaking trainer for your mind and your ability to communicate?
