Course Description

In this course you will learn everything you need to know to become a fitness trainer. You will start from the beginning so you don't need any prior knowledge about fitness or exercising (however if you do, that makes it easier).

This course is taught by Jeroen who is an internationally certified personal trainer and internationally certified nutrition coach with over 12 years of experience helping clients and teaching other personal trainers and nutrition coaches how to better help clients reach their goals.

In this course you'll learn everything you need to know to start as a fitness trainer and we build a solid foundation that you can use in the future to better your skills.

You will learn about the anatomy of the human body and how it relates to personal training. We'll discuss the skeleton and the different bones and how these function in the different types of joints. Then we will discuss what muscles are, the different fibers and the function of each individual muscle and how to train it.

We'll even go in more detail about the heart muscle and how it functions within the respiratory system, how we can improve this and how to measure the efficiency. Do you know what the parameters of the cardiovascular system are? By the end of this course you will.

We cover a lot of theory which is important for a fitness trainer, to understand how the body operates and how to improve postural problems. To improve the way the body of client moves you need to be able to perform a screening, so that's something we definately discuss in depth in this course.

And combined with the theory, there are practical lessons and videos as well. You'll learn how to perfrom a screening, SMR and stretching. Of course we will go over all the important exercises and how to execute them and you'll get tips and tricks to get the best results. And finally you'll learn how to set up a training program for different training phases.

So if you want to become a fitness trainer then this is the course for you!

Instructor Details

Jeroen Offergelt

Hi There,

My name is Jeroen (Jay-rone).

Who am I and what is it that I do?

I have diplomas in business management, hospitality management and business administration. I'm also a certified personal trainer and nutrition coach.

After starting my career in the hospitality industry I moved on into the retail- and fitness industry.  From there on I started a catering- and a fitness company. When I'm not coaching clients in the fitness studio you can find me in front of the classroom.

I've been a teacher for over 14+ years. I teach hotel-,  business-, business administration- and restaurant management at college. Besides the business side of teaching I also educate and train new personal trainers and nutrition coaches.

I have quite a few fields I'm interested and passionate about.

And now I hope to teach and inspire you as well via the online way of teaching.

Enjoy the courses!

Jeroen

So far, I appreciate the point making of how this can be different for everyone and based off of theory, so ensuring to practice, study, and become familiar with these theories is important.
