A Few Words From Me


Level 3 Personal Trainer, Creator of Personalised Training Programmes and Nutrition Consultant

Hi, I’m Jeff Turnbull and the founder of TURNFIT. I became a Sudbury Personal Trainer after making my way to fitness following a life-saving operation a few years ago. Having emerged the other side and achieved my goals, I am now using my skills, experience, and journey to help others.

I care about my clients, and there’s nothing more important to me than helping someone go through an experience that’ll make them happy, confident and strong. Furthermore, I know how being unfit and overweight can affect all parts of your life, and I want to be there for those who wish to bring about change. I want to help you discover the benefits of training that have helped me become the person I am today, and I’m here to guide you every step of the way.

I understand life can be hectic, and it’s often tough to find time to work out; I’ve been there myself and have made every excuse going. Now, I’ve used my experience and training to design programmes that are manageable, enjoyable and proven to work.

What Clients Say

Jeff is a fabulous guy and really knows his stuff. He is so passionate about helping me achieve my weight-loss and fitness goals. My programme was devised to allow me to progress to more and more developed exercises. The workouts are always different and I always look forward to each session. Highly recommended!”

Duncan L, Halstead

Before I first started training with Jeff, I was tired all the time and just didn’t enjoy exercising. As I was getting older, I knew it was time to get myself a knowledgeable person to help me out. Our sessions always feel tough, but always with an element of fun – enjoyment being so important to keep me motivated. 2 months in already and I have lost weight, I feel 100% fitter and I feel more energised!”

Nicola P, Braintree

I’ve been meeting Jeff for about 6 weeks and look forward to my sessions with him – my body always feels like it’s had a good workout. I like the mixture between flexibility, strength and aerobic and have found training outside really refreshing. The range of equipment Jeff brings along is great; I particularly enjoy using the resistance bands and kettlebells. Jeff has a natural way of getting more out of someone! I have benefitted by becoming stronger, leaner and have much better posture. I would definitely recommend Jeff to anyone, at whatever level of fitness.”

Jacqui G, Chelmsford

Jeff has made exercise fun again! I have been doing home workouts for a few years, but I just wasn’t seeing results anymore and so I lost enthusiasm. Jeff has introduced me to a whole new way of training and continues to show me new and fun exercises! He has helped me with my diet too and now not only am I seeing results again I am now looking forward to my sessions.”

Martin A, Dunmow

Jeff really listened to what I wanted to achieve and put together a varied workout plan for me to follow, which was regularly updated over the months. Jeff pushed me and his motivation and enthusiasm was a real driving force to help me persevere and challenge my ability, I didn’t want to let either of us down!

 Jeff is a knowledgeable and personable personal trainer that I trust and value his guidance to drive me forward.”

Anna J, Braintree
