Hi! I'm Felicia Oreb. Here is a little insight into my life and how I became a personal trainer and one half of one of the worlds most recognised fitness brands - Base Body Babes.

Straight out of high school, I began studying to become an Interior Designer. After 4 years of study, I completed my Bachelor Degree in Design, majoring in Interior design. At that point, I had no idea that design would not be the career path I would eventually take, but it definitely helped create the brand that would mean the most to my sister and I, our beloved Base Body Babes.

In 2008, I married my high school sweetheart, who was a Personal Trainer at the time, so I was already involved in the fitness industry with him. However, I did not begin my career in Personal Training until 2010, after I gave birth to my daughter. At the time, I had decided to get back into shape by training with my husband Sebastian Oreb (@australianstrengthcoach) who is one of the worlds best strength coaches. My sister Diana was working at the child care centre where I was taking my daughter and everyday at school drop off, other mothers would ask what I did to get back into shape. Diana had already completed her Personal Training Certification and was regularly training herself and others outside of her day job. We would get daily requests from the mothers at the school to train with us and this is what prompted us to start an outdoor bootcamp for mums. It was not long after this that other women (not mums) began to notice us and the results we were getting for our clients and soon enough we were approached to help them get into shape also. This is when we expanded our business and created our online training service. We wanted something that would cater for all women and we wanted to help more people than those in our local surroundings, so Base Body Babes was born.

Now, years later, as experts in our field and digital influencers, with two gyms, a cafe and a successful online training business, we want to help more people than ever before become confident with lifting weights. We have developed what we believe to be the best virtual personal training experience in the world today and we want to help you reach all of your health and fitness goals.

So if you want to transform your life, we would love to be the trainers to help you make it happen. To train with us and other amazing women, join our Base Body Babes Online Program. We can't wait to help you!

Lots of Love,

Felicia xx

Hi! I'm Diana Johnson. Here is a little insight into my life and how I became a personal trainer and one half of one of the worlds most recognised fitness brands - Base Body Babes.

I have been passionate about health and fitness for a long time now. I was always a sporty kid and started training in the gym in my mid teens, I even employed my own personal trainer when I was 16 years old. Out of school, I studied childcare and completed my degree in Early Childhood Education and began directing childcare centres around Sydney. I loved my work, I love helping people and have always been a nurturer. I also really loved training and studied Personal Training initially out of my own interest in the industry, I wanted to learn as much as I could so I could train myself and my friends.

It wasn't until 2010 when my sister had her child and she completed her certification, that we both decided to change careers and start our new business. Once we started training and helping others, everything shifted for us and we knew this was what we wanted to do and as sisters, the fact that we could both do it together was even better. We felt like we really had a lot to offer our clients and women in general, we loved helping them achieve their goals and changing their lives, it was a no brainer for us, this is what we were destined to do.

We want to share our knowledge and experience with as many women as possible to help them feel happier, healthier, fitter, stronger and more confident than ever so they can live their best life possible.

So if you want to transform your life, we would love to be the trainers to help you make it happen. To train with us and other amazing women, join our Base Body Babes Online Program. We can't wait to help you!

Lots of Love,

Diana xx

“Absolutely love BBB! All the PTs are absolute goals. Best music, best energy, best workout and insane results. Leave there with such good vibes every time. ”

Emily Gialouris

“Training at Base Body Babes Studio is like nothing else. The support and encouragement is outstanding throughout every session. Each four week phase is a new challenge, which keeps me motivated. As a result from training with the BBB team I feel stronger than ever and more confident. Thanks to all the Babes for the love and support throughout the last year that I have been training at the studio. ”

Shelby Hart

“I am so grateful for Base body studio, a gym full of the most supportive and encouraging women. It is truly my happy place. I have trained at loads of different gyms in the past and for me the difference is that all the instructors are at the top of their game with so much knowledge and so motivating. They have pushed me far beyond what I thought I was capable of and continue to do so. After having two babies back to back with two c-sections my body had some big changes happen with allot of weight gain. After a year of training hard and nutrition guidance and support from the team at base body babes I am back to my pre baby weight, so happy and full of energy. So thank you Im honestly so grateful for all your efforts and constant support and motivation. I look forward to a new year of smashing new goals at base body studio ☺️ ”
