unlock fitness.

We’ve teamed up with the best local specialists to offer you a joined-up and truly personalised fitness experience…  

Jonny Bruce

Founder, Head Personal Trainer and Sports Massage Therapist

Jonny’s been a personal trainer for almost a decade and a sports massage therapist for five years, starting out his career working mainly in local gyms until he started Unlock Fitness back in 2018. He loves now having more freedom to develop properly-tailored fitness plans, working with people in a way that can take their particular lifestyle, body, and needs into account.

He’s got a BSc in Sport and Exercise Science as well as qualifications in Personal Training, Sports Massage Therapy, and Electrical Muscle Stimulation. When he’s not playing sports (which is most of the time) he loves watching films and going to stand-up comedy shows, and he also enjoys walking holidays in Scotland and running marathons.

Becky Dean

Personal Trainer and Pilates Instructor

Becky’s been working as a personal trainer and Pilates instructor for almost 15 years, with a particular focus on pre- and post-natal health. She’s also run almost every kind of fitness class under the sun in her time, from Zumba and dance aerobics to spinning, body pump, and circuit training. She loves helping people find the joy in exercising, learning what motivates and interests them and seeing them get to a point where they actually enjoy their workouts.

She’s got qualifications in Personal Training, Pilates, TRX, and Advanced Kettlebells, and is currently studying for a qualification in Women’s Health. She’s a busy mum of three under three, her favourite treat is Nutella straight from the jar, she enjoys dancing and doing yoga to relax, and she once got to meet the Queen.

Nichola Shuttle

Wellness Coach

Nichola’s been working as a wellness coach for about 7 years, helping people feel happier and healthier in their day-to-day lives by making positive changes to their habits, diet, and lifestyle. She’s worked with people struggling with everything from food intolerances and sugar addiction to diabetes, menopause, and cancer, and she loves getting to be part of so many different and interesting health journeys.

She studied holistic nutrition (specialising in health and wellness coaching) at the Institute of Integrated Nutrition, graduating in 2015. She grew up in South Africa and still loves going on safari, although she now lives here in Buckinghamshire with her husband Jamie, her cockapoo Lottie, and her two teenagers. Her early career was spent as a shoe buyer for Pied a Terre, she enjoys wild swimming, is proud to have competed as part of the GB sprint triathlon squad in the 2021 European and World championships, and her favourite type of food is Indian.

Jenny Murray

Physiotherapist

Jenny’s been a chartered physiotherapist specialising in musculoskeletal injuries for 25 years. She’s got a particular interest in helping people understand and manage chronic pain, along with understanding their acute injuries to make sure they not only make a full recovery but also finish their treatment stronger, fitter, and performing better. As well as being skilled in a wide range of physiotherapy techniques, she’s also experienced in treatments like hydrotherapy, taping, and acupuncture.

Jenny qualified as a physio from The Middlesex Hospital London in 1993, and is a member of The Chartered Society of Physiotherapy and The Acupuncture Association of Chartered Physiotherapists as well as being registered with The Health and Care Professions Council. She grew up in the Middle East and the Seychelles, although she’s lived in the UK since qualifying – moving to Amersham 20 years ago. She loves skiing, sailing, and cooking Asian food, as well as long walks in the Chiltern Hills with Alfie (her fluffy white Maltese).

James Baker

Physiotherapist

 James has been working as a chartered physio for just over a decade, in both NHS teaching hospitals (including the world-renowned Royal National Orthopaedic Hospital in Stanmore) and also a private practice context. He loves to take a holistic approach to treatment, especially injury recovery, and has extensive experience in hydrotherapy, acupuncture, and chronic pain management as well as standard physiotherapy techniques.

James qualified as a physio from St Georges Hospital London in 2011, and also has training in Sports Massage Therapy. In a previous life he coached youth football for Wycombe Wanderers FC and he still loves playing football for his local team. He also enjoys cooking, hiking, and going to the gym.

Trisha Duffy

Pilates Instructor

Trish has been teaching group exercise classes in everything from step aerobics and spinning to aqua fit for 26 years, although her focus now is on Pilates. She loves to get people moving and watch how staying active helps them feel better about life and about themselves, as well as growing in confidence and making new friends. Her classes have also helped people struggling with things like back pain, scoliosis, and osteoarthritis.

She’s got qualifications in both Pilates (mat-based and machine-based) and Nutrition and Weight Management. When she’s not teaching she loves to be by the sea or out cycling, and the rest of her spare time is taken up with training her new puppy or helping take care of her small grandchildren (two remarkably similar activities!) Impressively she’s also climbed Mount Kilimanjaro, in order to raise money for a dementia charity.

Marie Caublot

Osteopath

 Since qualifying, Marie has worked with patients in both private and NHS-integrated settings.  She now runs ‘The Tilsworth Clinic’ at Unlock Fitness, caring for patients with both acute and chronic musculo-skeletal problems.  She has particular interests in healthy ageing, women’s health and advice for sportspeople. Marie has a Masters in Osteopathy from Swansea University and is a Member of the Institute of Osteopathy.

In her spare time Marie sails, is a qualified windsurfing instructor, rides horses and plays rugby for Marlow Ladies.  And if that’s not enough, she also has a post-graduate certificate in Animal Osteopathy and is continuing her post-graduate studies (though you can’t bring your horse to Unlock Fitness – we can’t get it through the door!). 

Dan Whittall

Personal Trainer and Sports Massage Therapist

Dan may be our newest and most recently qualified coach but he’s already clocking up his hours in the space, as even when he’s not there with clients he likes to work out almost every day. For him fitness isn’t about giving everyone a six-pack (unless that’s exactly what they want) – he’s focused on using exercise and massage to help people better manage and enjoy their day-to-day life.

He’s got a first-class degree in Sports Studies as well as qualifications in Personal Training and Sports Massage Therapy. He loves playing rugby and riding his skateboard, his favourite holiday destination is skiing in the Alps, his guilty pleasure is pizza, and he has a strange but very strong dislike of frogs.

“I love the private workout space at Unlock Fitness and the personalised training I get. The calm, encouraging coaching style of Jonny and the team pushes me, but without any intense boot-camp-style delivery. And I especially appreciated the effort that went into keeping both me and my family fit and healthy all through the lockdowns.“

Mona

“In the past I was never particularly active - but for the last 5 years I’ve been coming to Unlock Fitness weekly (often twice weekly) and that’s all down to Jonny’s ability to make our sessions so fun and enjoyable. Despite being in my late 40s, I have never felt better. Jonny is a great motivator and always keeps the sessions fresh. I really can't recommend Unlock Fitness highly enough.”

Benedict

"I’ve been training with Unlock Fitness for nearly 10 years and I have no intention of stopping. The coaching has always been great - fun, targeted to my goals, and motivating me to push myself in the sessions. Plus the space itself is light and bright and a good place for people of all levels of ability to train."
