Hi! I am Mark Foster, a London-based personal trainer and fitness expert at Threo. With an extensive background in personal training, I have spent over a decade helping clients achieve their fitness goals through tailored workout regimes and nutritional guidance.

My journey into writing began as a way to share my knowledge beyond the gym, and I quickly established myself as a trusted voice in the fitness community. My articles cover a wide range of topics, including effective workout techniques, the latest in fitness technology, and in-depth reviews of gym equipment. My work in Threo aims to educate, motivate, and inspire readers to lead healthier, more active lives.
