Athlete from the Very Start

Katie Sonier’s passion for an active lifestyle dates back to her time playing competitive sports throughout her days in high school – playing lacrosse and taking part in gymnastics.

Playing competitive sports throughout her teenage years taught Katie to always remain focused, work hard, and stay committed to reach all of her fitness goals. Because of this, she was able to build a reputation as a formidable lacrosse player.

However, between the ages of 16 and 18, Katie’s height soared from 5 ft 3 to 6 ft. Because of this, Katie felt self-conscious about the way she looked. During this time, her self-esteem dropped to an all time low. Ultimately, she reached a point where she began to battle against depression.

But one day, Katie sought a way to improve her self-confidence. It was at this point, she turned to the weights room to achieve just that.

Becoming Passionate about Fitness

By working hard to gradually build up her strength and physique, Katie quickly made progress with her weight training sessions. As a result of her hard work, she was able to form the foundation to build a great physique.

Because of her quick progression, Katie became fascinated with fitness and the results that came along with consistent training. Because of this, she soon realized that she wanted to take a different direction in her academic career.

It was at this point, Katie made the decision to change her major at university from Economics to Applied Psychology and Kinesiology. From this moment, Katie kept pushing on to pursue a career in fitness.

Ever since then, Katie has earned a degree in something that she’s passionate about – becoming a qualified kinesiologist in the process. After realizing that fitness totally transformed her life, she set out to help others follow in her footsteps – becoming a personal trainer to inspire others to reach all of their fitness goals.

Soaring to Fame

From a teenager who was insecure about her looks to becoming an influential personal trainer, Katie has turned her passion for fitness into a successful career.

After reaching all of her fitness goals, she’s gone on to achieve social media fame. Because of this, Katie has been able to inspire people all over the world to achieve their full potential in fitness – just like her.

Katie has become renowned on social media for her intense training sessions and flexibility. Speaking of the importance of flexibility, Katie stated:

“When you improve flexibility, you improve your range of motion. Which then means you can move more optimally, meaning more opportunity for making progress and building muscle and puts you at a lower risk of injury”.

She regularly displays her training methods across her social media pages, such as performing barbell shoulder presses, while in the ‘splits’ position.

Katie places focus on training her lower body, in particular her hamstrings and glutes – her favorite muscle groups. Some of the exercises that she performs regularly are listed below:
