Briana Sabella
Originally from San Francisco, I moved to London in 2021 to attend Le Cordon Bleu Culinary School. While searching for balance in my job as a pastry chef, I discovered a passion for health and fitness and went on to earn my certificate as a Nutritional Advisor through the Royal Society of Public Health.
Alongside nutrition, I trained to teach group fitness and spin. With a background in music as well, I love to create energetic, fun and motivating playlists. I believe exercise and nutrition are forms of self-care - not chores - and I am passionate about sharing that mindset so others can feel strong, happy and confident along their health journeys.
