Bio

I’m Mark Lyall, an MSc-qualified Personal Trainer with a passion for helping people build strength, confidence, and long-term health through evidence-based training. My coaching philosophy centres around three key principles: Movement, Muscles, and Mind. I believe mastering movement quality is the foundation for achieving any fitness goal safely and effectively.

Whether you’re completely new to the gym or an experienced athlete looking to improve performance, I create personalised programmes that match your goals, biomechanics, and experience level. Every plan is built using the latest exercise science to maximise results while reducing injury risk.

Alongside training, I provide practical nutrition guidance, including calorie and macronutrient targets, helping clients build sustainable habits rather than relying on quick fixes. I offer one-to-one coaching, small group sessions, hybrid coaching, and app-based programmes to suit different lifestyles.

Outside of coaching, I enjoy resistance training three to four times a week, running, football, and recently completed my first HYROX event. Challenging myself physically allows me to better understand the journey my clients are on and coach with both experience and empathy.
