Sarah Mariko
Fitness Coach
Sarah Mariko has over eight years of experience in the fitness industry, specialising in group exercise and one-on-one personal training. She has coached thousands of people worldwide, from London to Los Angeles, Sydney, and Dubai.
She coaches high performing business women one-to-one who recognise the importance of exercise in enhancing their brain health, focus and performance at work.
In 2020, Sarah launched MOVE With Mariko, a fitness app designed specifically for women, leveraging her extensive industry knowledge to create a supportive and empowering global community. Her platform has gained recognition for its practical and realistic approach, proving that you don’t need to spend hours training to see results -just a little movement every day can make a lasting impact both physically and mentally.
Through years of coaching, Sarah has identified the biggest challenges people face: lack of time, inconsistency, and the struggle to build a sustainable fitness routine. Her mission is to tackle all three by promoting a flexible, enjoyable, and realistic approach to fitness.
"I want people to love fitness -to see how movement enhances their day and makes them feel stronger, more confident, and more energised. It’s not about perfection; it’s about showing up for yourself every day.
