Roice Gummer
Head Coach, General Dogsbody at CrossFit Thurrock

CrossFit Thurrock was created with one simple mission: to help everyday people become stronger, healthier and more confident — both inside and outside the gym. My name is Roice Gummer, and fitness has been a huge part of my life since I was 7 years old and first learned to kick a ball, playing for Little Thurrock Dynamos, Grays Cosmos and eventually Thurrock FC (formerly Purfleet). After serving in the military and spending years working as a Personal Trainer and nutrition coach, I realised something important: Most people don’t struggle because they don’t know that exercise is good for them. They struggle because they lack the right environment, the right support, and a plan that actually fits into their life. I wanted to create a gym that was different from the traditional fitness experience — somewhere people weren’t left wandering around with no direction, feeling intimidated or unsure what to do. That idea became CrossFit Thurrock. When we opened our doors, the goal was never just to create a place where people could work out. The goal was to build a community where anyone could walk in, regardless of their starting point, and feel welcomed, supported, and coached. Whether you’re a complete beginner stepping into a gym for the first time, someone looking to lose weight and improve their health, or an experienced athlete wanting to push your limits, our approach is the same: Great coaching. A supportive community. A proven plan. Consistency over quick fixes.

Over the years, we’ve helped thousands of people locally transform their fitness, improve their confidence, and build healthier lifestyles. We’ve seen members achieve things they never thought possible — from losing weight and getting stronger to simply having more energy to keep up with everyday life. What makes CrossFit Thurrock special isn’t just the workouts. It’s the people. It’s the friendships built during early morning sessions. It’s the encouragement when someone achieves their first pull-up or lifts a weight they never thought possible. It’s the community that makes turning up each week something you actually look forward to. My promise is simple: every person who walks through our doors will receive expert coaching, genuine support, and a place to become the best version of themselves. If you’re looking for a gym in Thurrock where you won’t be another membership number, where you’ll be coached properly and where you’ll be surrounded by people who want you to succeed — we’d love to welcome you to CrossFit Thurrock.

With a background in the military, qualifications in personal training and nutrition coaching, and years spent working with people of all different abilities, Roice brings a wealth of knowledge and practical experience to every session. His coaching philosophy is simple: meet people where they are, help them understand what they are capable of, and give them the tools and support needed to keep progressing. Roice believes great coaching is about more than just writing workouts. It’s about understanding the person in front of you — their goals, their challenges, their lifestyle, and what success looks like for them. Whether coaching someone taking their first steps into fitness, helping a member improve their strength and technique, or supporting someone chasing a new personal best, Roice focuses on creating an environment where people feel challenged, supported, and confident. With his background in nutrition coaching, he also understands that achieving results goes beyond what happens inside the gym. He helps members build sustainable habits around training, food and lifestyle so they can create changes that last. One of the things Roice enjoys most about coaching is seeing the moments when people put effort in that they didn’t know they were capable of. Simply being willing to try their hardest, regardless of ability, is how Roice likes to lead his sessions. Coach Roice’s goal: To help every member develop the confidence, resilience, skills and mindset to become the strongest version of themselves.
