My path into fitness wasn't a straight one. For years I battled a severe autonomic nervous system dysfunction, a heart condition requiring a pacemaker, and a list of symptoms that at times made even day-to-day life a challenge. I know what it's like to start from zero, rebuild strength, and push through setbacks. That journey gave me not just knowledge, but a real empathy for anyone working toward better health. Fast forward to today, I'm fitter and stronger than I've ever been, and I channel that experience into my coaching.

I have over 20,000 hours of personal training experience, working with a broad range of clients from Commonwealth athletes to 90-year-old musicians & clients in need of injury rehabilitation. With a huge focus on nutrition, gut health and lifestyle balance to allow you to make the most of your training and push the boundaries of what is possible.

I have over 10+ years of experience in the fitness industry, with vast knowledge of sports performance, body recomposition and nutrition, specialising in working with individuals with eating disorders and athletes who need support with their nutrition, in person and online. I hold a BSc in Sport, an MSc in Public Health Nutrition, Level 3 PT and coaching qualifications, and recently completed my PE teaching degree. I have recently retired from professional rugby league, having played for Castleford Tigers, Bradford Bulls and Wigan Warriors, as well as the England Rugby League set up and Rugby League Ireland.

I have been in the fitness industry since 2014, starting out in commercial gyms and working my way up to General Manager. This gave me a strong understanding of how gyms run, the importance of customer service, and most importantly how to help people feel comfortable and supported in a gym environment.

In 2016, I began personal training alongside my management role and quickly realised coaching was where my passion truly was. I made the move to full-time PT, focusing on helping people build confidence, strength, and sustainable habits.

With over 10 years in natural bodybuilding, including a 3rd place finish at British Nationals, I have developed an in-depth understanding of training, nutrition, and mindset. In 2025, my coaching reached the world stage, helping a first-season bikini athlete become a World Champion in LA, bringing the title back to Britain.

Alongside bodybuilding, I have also trained in powerlifting and continue to invest heavily in my education, working with some of the best coaches in the world to refine my own coaching systems.

Through ATKNSN Coaching, I focus on long-term transformations that fit real life. My coaching style is collaborative, supportive, and tailored to each individual, with no quick fixes, no extremes, just sustainable results you can maintain for life.

With over 11 years' experience in personal training, I now specialise in transforming women into stronger, radiant, confident versions of themselves.

I have a background in competitive powerlifting & bikini bodybuilding, which has allowed me to crack the code to getting in shape & maintaining it without the restrictive diets all year round.

You can usually find me dancing along with clients between sets to a decent song, or chasing my child around pretending to be Johnny Knoxville.

Outside of the gym I have a passion for travelling, festivals, as well as spending time with my little lunatic family.

I'm dedicated to helping people of all fitness levels build strength, confidence, and long-term results through structured weight training.

I've worked with clients ranging from 17 to 65 years old, creating personalised programs that support body recomposition, fat loss, and sustainable lifestyle change based on each individual's goals, abilities, and limitations.

My experience includes working with clients managing a wide range of injuries, recovering from surgeries, living with disabilities such as cerebral palsy, and those new to training or returning after time away. I take a safe, thoughtful, and personalised approach to coaching, with a strong focus on proper lifting technique, progressive overload, and building lean muscle while reducing body fat. I also offer practical nutrition guidance to support performance, recovery, and long-term weight loss.

I believe fitness should improve your quality of life, not intimidate you. My coaching style is supportive yet challenging, and my goal is to help every client get stronger, move better, and achieve lasting results both inside and outside the gym.
