MEET THE TEAM
SCOTT MARSH
Bsc. (Hons), C.S.C.S
FOUNDER & HEAD COACH
Scott Marsh is dedicated to helping individuals transform their lives, drawing from his own remarkable journey of weight loss and lifestyle change.
In 2006, Scott lost over 100lbs and 18” from his waist through self-motivation and lifestyle adjustments, giving him a unique insight into the challenges and rewards of such a transformation.
As a personal trainer, nutritional coach, and mindset coach, Scott specialises in working with busy professionals who struggle with motivation, stress, low energy, niggling injuries and who have difficulty losing weight. He uses his own experiences to guide his clients with empathy and expertise.
Inspired by his own personal weight loss success, Scott decided to shift careers to help others achieve their goals. He gained valuable experience as Head Coach at Phoenix Pro Fitness under Charlotte Ord, Personal Trainer of the Year 2010 and coach of ‘The Biggest Loser’.
From there Scott has continually pursued further education, studying with top trainers, nutritionists, and coaches globally. He is an accredited member of the prestigious NSCA (National Strength and Conditioning Association) and the UKSCA (United Kingdom Strength and Conditioning Association), both considered gold standards for elite trainers.
Recognising that true transformation extends beyond just physical training, Scott became a qualified nutritional coach and delved into mindset coaching. He studied NLP, Mindfulness, and Dax Moy’s ‘Mindmap Mastery’ to help clients overcome lifelong struggles with food and escape the diet rollercoaster.
In 2017, Scott entered a Duathlon with a client despite having no sporting background. After placing well in his first race, he was motivated to pursue competitive sports further. Within a year, he qualified for the GB Age Group Team and represented the country at three world championships.
With almost 2 decades of experience and having helped thousands of clients aged 7 to 77 transform their bodies and lives, Scott has developed a series of systems that deliver rapid, lasting results in a fun and motivating atmosphere.
With his endless enthusiasm, infectious energy, and unwavering passion for client success, Scott is the ideal trainer for those who wish to embark on a transformation journey to lose weight, boost energy, and feel better, guided by someone who has been there, done it and achieved remarkable results.
SAMMY STONE
FITNESS COACH
Meet Sammy Stone, one of our dynamic and inspiring coaches here at Xcelerate Fitness. With a deep passion for health and fitness, Sammy brings both experience and empathy to the table, making her the perfect guide for anyone looking to transform their body and mindset.
Her journey into the fitness industry began after a career change post-lockdown, following her studies in Graphic Design. Realising that her true passion lay in helping others, especially within the health and sporting world, Sammy dove headfirst into coaching—a natural extension of her lifelong love for fitness.
Sammy’s personal fitness journey is rooted in overcoming challenges. Throughout her teens and young adulthood, she struggled with gaining weight and often felt unhappy and weak. Martial arts became her outlet, and through the intense discipline of daily training, she rebuilt her strength, boosted her confidence, and honed her body for performance. As a Black Belt Kickboxer since 2019, Sammy knows firsthand the dedication and persistence it takes to achieve your goals, especially when injuries or setbacks arise. Her own battles with physical injuries taught her the importance of strength training, rehabilitation, and smart nutrition: lessons she now passes on to her clients.
A true athlete at heart, Sammy has trained in martial arts since she was 10 and recently added a Triathlon and Brazilian Jiu-Jitsu to her ever-growing list of achievements. What she loves most about the fitness industry, though, is the opportunity to connect with people from all walks of life, helping them find their strength, achieve their goals, and embrace healthier lifestyles.
Outside of coaching, Sammy is a woman of many talents. Whether she’s perfecting a crochet project, keeping a meticulous eye on the daily running of Xcelerate, tending to her ‘studio plants’ or sharing her martial arts expertise, she approaches everything with a passion and energy. Sammy’s blend of friendliness, professionalism, and lived experience makes her not only a relatable coach but an inspiring one. Whether you're looking to lose weight, tone up, or simply improve your health, Sammy is here to help you every step of the way.
SEKHAR UTHAYAKUMAR-CUMARASAMY
FITNESS COACH
Sekhar played various sports at school including football, cricket, and took part in middle-distance running, but started taking his fitness seriously after starting Taekwon-Do aged 14.
After finding his passion he progressed through the ranks to 4th Dan black belt, whilst assisting in the coaching of classes and eventually building his own club in 2009. Sekhar has also competed both nationally and internationally in his sport.
Taekwon-Do helped Sekhar learn about the physical and mental benefits of regular exercise, the pitfalls of overtraining, and how to manage his weight and nutrition, particularly in preparation for competitions.
As time went by Sekhar decided to train up as a personal trainer so that he could apply his coaching skills on a more personal level to a broader client base.
He has a keen eye for technique and likes to push his clients appropriately so they can get the very most out of their sessions whilst having fun along the way!

Nicci’s interest in health and fitness whilst on her own journey.

After several years of unsuccessful dieting and low-self esteem, she eventually found a solution which combined medicine and diet - resulting in a three stone weight loss and a new lease of life.
Never looking back, Nicci went on to become an avid runner and gym goer, eventually retraining as a PT in her early 40’s. Keen to share her education and experience Nicci runs regular ladies bootcamps and fitness sessions in care homes alongside coaching semi-private and private training sessions here at Xcelerate.
CHARLIE BONWICK
FITNESS COACH
Charlie’s journey into fitness has been anything but ordinary. Growing up, rugby was his world—until life as a chef meant he had to hang up his boots. Searching for a new challenge, he discovered the gym and never looked back. What started as a way to build muscle to support his body from getting injured it soon became a passion, with training sessions squeezed in between split shifts and late nights in the kitchen. Before long, he was helping friends transform too, which inspired him to step away from full-time cheffing and pursue a career in personal training.
For Charlie, the gym is all about progress. He loves the idea that you can always push further, lift heavier, and prove to yourself that you’re stronger than you thought. That constant pursuit of “better” is what drives him—and what he loves passing on to others.
Sport and movement have always been part of Charlie’s life. From earning a junior black belt in Taekwondo, to years on the rugby pitch, to his long-standing passion for bodybuilding (with competing still on the horizon), he thrives on challenge. And with a fine dining background, he also knows his way around a kitchen—whether it’s enjoying food from all over the world or creating healthier twists on favourite dishes.
A couple of fun facts? Charlie’s secretly a budding artist, and once tried his hand at tattooing (with a questionable leg tattoo to show for it)!
As a coach, Charlie’s mission is simple: to help people realise they’re capable of more than they think. He wants to show that fitness doesn’t have to be boring—it can be fun, exciting, and empowering. For him, results drive motivation, and he’s here to make sure his clients surprise themselves with what they can achieve.
