Bettina Sagi

Swiss Cottage Leisure Centre


My journey started with being active at the age of 8; 5 years in rhythmic gymnastics and 8 years in amateur horse riding. 

I had an accident at work in my early 20s and dislocated one of my kneecaps. A few years later in 2012 when I started to work at the cafe of Swiss Cottage Leisure Centre I met one of the personal trainers, Susanna Karpati. I regularly trained with her 3 times a week. With her knowledge, motivation and inspiration I went through major life changes. I gave up bad habits such as unhealthy eating, being inactive, stopped smoking after 10 years and she helped me to fully recover from my knee injury. In 2015 I changed my job and started to work as a Fitness Manager and Fitness Class Lead for GLL for 4 years and regularly attended courses, as well as learning from my Mentor, Susanna. 

In 2019 I decided to change my career to help others reach their goals and dreams the way I did. Im currently working as a Personal Trainer in Swiss Cottage and as a Group Exercise Instructor teaching 10 different types of classes for Better.

I am so proud of my first client, Julia as she did incredible well on her weight loss journey so far and lost 30 kgs/66 pounds since October 2017.
