About Me
Mark Etherton - Qualified Gym Instructor / 1-to-1 Boxing for Fitness Trainer
I’m passionate about fitness, wellbeing, and helping people feel stronger both physically and mentally. After years working in high-pressure environments, I experienced firsthand how powerful exercise can be for improving confidence, reducing stress, and creating a healthier lifestyle.
That passion led me to create CoreBox Fitness, a fitness community built around boxing-inspired training, movement, and support. My goal is to help people improve their fitness, build real strength, increase confidence, and enjoy training in a positive and motivating environment.
BoxFit is an exceptional workout and it’s about feeling better, moving better, and becoming the strongest version of yourself.

Everyone's welcome!
Whether you're brand new to fitness or an experienced athlete, our sessions are designed for all ability levels.
