I work with a diverse range of amazing clients from different backgrounds, experience and lifestyles. I focus on identifying my client's fitness goals, helping them to become fitter and stronger for life. I can work with you in a number of ways to suit your budget and availability from 1:1 training, group sessions or even a spinning class. We can work together either in person, in the park or at home or I can work with you online, so we are not restricted by location.

Client Testimonials

I have a long-term condition and keeping strong and flexible is important for my health.  After a recent issue with bursitis in both hips which led to problems with my knees, Sara adapted my training plan to help me to keep attending sessions with her while protecting joints and muscles where needed.  As this has now lasted for over 3 months, she has helped me maintain muscle strength and general fitness during a period when I could easily have given up and retired to a chair!  I am very grateful to her for her knowledge and patience as she has coached me through this frustrating time!
Sarah – Online

We’ve been working together for just over a year now and I’ve really seen a big impact in my game following our sessions. Sara is constantly keeping the sessions fresh and open to feedback on ways I think we might be able to get more out of them. Often, I can be overzealous with my requests which she’s very good at keeping me in check and focussed on my goals.

The weekly sessions are a welcome respite to the monotony of work & family life – Not only being a great trainer, Sara is also a fantastic listener. In between sets (which often isn’t a lot of time – @Sara hint hint), I have the chance to offload some of my life challenges. However trivial they may be, Sara always has a kind word to say or helps to rationalise.

I’d recommend reaching out to Sara to help with your health & fitness goals. She has a wealth of knowledge; and if something isn’t within her repertoire, she’ll go away and research it ready for next time.

Matt – Touch rugby player

I have just completed my first block of sessions with Sara and I am really enjoying it. I no longer live in the UK but as all training has been online recently I thought I would try virtual PT. The virtual aspect of the training has not been a problem at all. What I most like about Sara is that she asked up front what exercises I hate. She also really listens to my feedback about how I am feeling, muscle pain etc, and modifies workouts accordingly. I look forward to the sessions and because of the variety of exercises it doesn’t feel boring. Sara was recommended to me by a good friend and I would definitely recommend her to anyone. She is professional, communicative, really friendly and easy going too. I am really happy that I started working with Sara and I already feel stronger and healthier!

Nicola – Basel, Switzerland

As an anxious and easily stressed individual, Pilates has helped me to take a breather and relax my mind. It’s the only time in the week where my mind isn’t flipping somersaults and I’m able to focus on just me! Sara has helped me to refocus on my strength and instantly helps me to relax within the first moments of a session. Starting with a full body roll down or just some basic shoulder rolls and slow breathing, I’m immediately transported to calmness. I’ve started to see such an improvement in just three months; reduced anxiety, stronger in my core and the ability to better control my breathing.   So far, Pilates has been enormously refreshing and I look forward to continuing to build on my strength and working with Sara, who has been so tremendously fabulous and patient throughout!

Laura, Windsor based online client

“I have been doing Sara’s outdoor fitness classes twice weekly for about 10 weeks (via Zoom during lockdown). They are very enjoyable with a great variety of exercises. Sara is great at motivating you, so whether you are just starting out or are someone who already exercises you will benefit from her sessions. Would definitely recommend.”

Aileen, Windsor


“I never thought I’d find a class where exercise doesn’t seem a chore but Fitness in the Forest is always fun and varied. I always leave feeling energised and set up for the day. I love these sessions :)”

Niki, Windsor (Busy Mum)

“I love the Fitness in the Forest session every Friday, they are always fun, varied and challenging.  I come away feeling really positive and ready for the weekend.  Sara is not at all as I imagined your boot camp trainer to be, she is very knowledgeable and kind.  Thank you, Sara!”

Sophie, Windsor (Small Business owner and Mum of 2)

“Sara is amazing. She has listened to what I would like to achieve and work on and has tailored my workouts to suit me.  No pressure, just support. Thanks, Sara.”

Sharon – Mum of two

“Sara’s sessions are tailored very specifically to my needs (eg knackered knees!) & wants. She’s very encouraging, and her sessions are always varied & interesting.”

Debbie – Newly retired

“Sara is an excellent PT who is very dedicated to her work. I’ve been training with her for over 7 months and each session is thoroughly planned to suit me and my ongoing progress whilst also being mindful of pre-existing injuries.  She is highly knowledgeable offering advice when asked and also flexible, regularly adjusting sessions on the spot to incorporate my toddler when necessary!”

Sumreen – Mum of two


When I start to work with any new client I find that there a number of commonly asked questions, especially if you have not enjoyed working with a personal trainer before.  To help you understand a little more about how it all works, please check out our FAQ section. Of course, do please get in touch with any questions that you may have.

There are so many benefits to spinning, some of them are:

  • Increased cardiovascular ability.
  • Improved endurance for outdoor cycling.
  • It’s really fun to ride both flat and hill to the rhythm of the music.
  • Loads of endorphins after the class.
