Thank you for visiting my site! 


I'm Jacqueline K.ossiwa T, a certified group fitness instructor accredited by the American Council on Exercise (ACE). Although I was born in Ghana, I was raised in Zurich, Switzerland, and have spent the past few years living in four different cities across the US, the EU, and Africa.

In addition to my role as a DE&I Specialist for a global firm, I am deeply passionate about fitness and work as a freelance fitness instructor. My offerings include online and outdoor fitness classes, centered around the philosophy of "Your Body is Your Gym," emphasizing workouts that require no equipment and are therefore suitable for all fitness levels.

The core principles of my approach encompass body strength, balance, endurance, flexibility, posture, breathing, and mindfulness.

Furthermore, I provide clients with personalised fitness programs and consultations, aiming to support individuals on their unique health and fitness journeys.

My fitness journey....

At the age of 10, I discovered my passion for sports, particularly short-distance running, basketball, and track and field. Throughout my youth, I actively competed in various athletic events across Switzerland, showcasing my skills.

Between 2009 and 2013, I proudly served as a police officer, breaking barriers as the first woman of African descent on the force. During this period, I not only upheld my duties but also stood out as one of the few female assistant coaches for the local police department. Simultaneously, I represented the Police Multi-Events Swiss National Team as an athlete, distinguishing myself in both law enforcement and athletic pursuits.

Upon relocating to the United States in 2013, I continued my athletic journey as a track and field competitor for City College of San Francisco. In both 2014 and 2015, I participated in the Long Jump and Heptathlon at the California Community College Championships held in Sacramento and Los Angeles.

Inspired by my extensive 15-year background in fitness and athletics, I made the decision to become a certified fitness instructor, eager to share my wealth of experience with others.

My fitness offerings


Presently, I provide inclusive online and in-person fitness classes suitable for all fitness levels. Drawing upon my experience as an athlete and the technical expertise gained through my studies, my classes integrate a holistic approach to physical well-being.


My sessions stand out for their unique blend of Africanbeat music, the integration of effective breathing techniques, and concluding each class with visualization exercises and meditation, providing a holistic mind-body experience.

Thank you for stopping by, and I eagerly anticipate welcoming you to my classes.
