Weight Loss Training

At Fitness Lab, we are redefining what weight loss training means & the results we deliver for clients.




Many of our clients come to the gym because they want to lose weight. All-too-often, they have developed a negative relationship with food and have begun to see exercise as a sort of punishment for eating or a chore that they have to do to lose weight. This is something we as a team are all incredibly passionate about addressing. We want people to find joy in movement and to feel empowered by gaining strength.

Our clients can expect to achieve hugely positive changes in their body composition, fitness, weight and strength, but more than this, their trainer will help them to find fun in the hard work and feel good about their bodies. We want you to celebrate all the important non-scale victories that you can achieve as part of a weight loss journey.

Some of the things we can help with include:

 Fitness assessment and monitoring

 Personalised training programmes

 Event preparation and planning

 Fat loss expertise

 Pre and post natal training

 Perform better, look better, feel better

Fat Loss London – How We Can Help

We are here to help every step of the way. First, after your initial free consultation, we’ll put together a step-by-step plan to map out the beginning of your journey with us and the goals that we will work on together. When it comes to fat loss, slow and steady wins the race. Other gyms might put you on a restrictive diet or promise a two week transformation. For the team at Fitness Lab, your long-term health and fitness is the priority. We want you to feel good for many years to come.

Your training plan will go hand-in-hand with the diet advice we give you – it’s crucial that both your workouts and nutrition are considered when it comes to weight loss, fat loss and body transformation.

Examples of Successful Weight Loss

“Jack and the team have quite literally changed my life. I started working with Jack a little over a year ago. When I started, I was unfit, allergic to exercise, overweight and generally unhappy but since working together things have turned around completely. I have fallen in love with exercise and as a result I’m fitter than ever, over 35kg lighter and simply much happier & more confident in myself. […] The benefits both physically and mentally are immense. I recommend Fitness Lab to anyone who will listen!”

Fat Loss Consultation

In your free consultation, your trainer will want to find out all about your goals and any training experience you have so far. This is where we start to get to know you, and is a great time for you to ask us any questions that you have about personal training with us.

Your free consultation is also an opportunity for your personal trainer to assess your movement and mobility. We take the time to learn as much as we can about your body, to make sure that your personal training sessions are fully tailored to your individual needs.

Guided By Experts

Our coaches are all qualified at the highest level and have a minimum of 5 years experience. They have the knowledge and expertise needed to get you from where you are now, to where you want to be. As a team, we don’t believe in basic instruction – we believe in high-level performance coaching. With your goals and needs at the heart of everything we do, we are committed to helping you reach your full potential.

Your trainer will put together a personalised programme with a clear plan, outlining week by week what results you can expect to achieve. As well as putting together session plans for the time you spend in the gym, they will also help you to keep up the hard work outside of the gym, too, with nutrition support all part of the package. If there are days where you can’t make it into the gym, there is no need to worry, as our trainers also offer online personal training, too.

Before you start training, your personal trainer will take the time to delve into your goals as well as your current dietary and lifestyle habits. From day one, they will help you to instil new, healthy habits that will last for life. For a lot of us, building an understanding around calorie intake and energy balance is the first step. Our team of trainers have the experience and expertise to guide you in a lifelong journey to feeling, looking and performing better than ever.

In the first few weeks of your training, the emphasis will be on teaching you “how to move”, building your confidence across all the fundamental patterns of movement. Daily check ins will help to keep you accountable when it comes to your activity outside of the gym and your nutrition.


You’re not alone – many of our clients have had the same experience.

A common problem is that, without the correct guidance, people will tend to adopt a really restrictive diet and an overly aggressive training plan, which is just not sustainable for fat loss in the long term. We want you to see your fat loss plan as just one part of a life-long commitment to your health and well-being.

Another problem is that – let’s face it – this journey isn’t an easy one! You need someone in your corner, encouraging you and guiding you every step of the way, making sure you’re doing what you need to do to get results. Without this support and expertise, it is all-too-easy to get disheartened and give up when results are slow to come.


This is unique to each person – your trainer will be able to give you a clearer idea of the time frame once they’ve taken you through your free consultation. Losing weight will usually require some lifestyle and nutrition changes, which you need to commit to doing outside of the gym, but your trainer will be there to support you every step of the way. In general, our clients start to achieve real progress in just a few weeks, whether that’s in terms of the weight on the scale, your body fat percentage or simply the way your body looks.

    5 star review  I have MS so have limited mobility. Ash has drawn me up a program to strengthen my core and upper body using resistance bands. The exercises, their purpose, which muscles were being worked were all clearly explained and demonstrated. Very excited about getting into the routine of using the program and I'm sure I will be going back to Ash for add ons. 10/10

Most of all, we have both loved working with our trainers. They’re committed to helping you transform your lifestyle and habits. They provide really helpful, tailored advice and are so positive and motivating! I have gotten stronger and healthier than I have ever been. It’s been such a wonderful experience to train with them, and with Sandra in particular!

Frequently Asked Questions

I’ve tried losing weight before but even after exercising I am struggling -why?

There are a number of reasons for this – one might be that you’re underestimating how much you eat, or underestimating how much you’re moving. Your trainer will be able to see what’s going wrong here. This is where a trainer’s experience can make all the difference – we’ve helped thousands of people on their fat loss journeys, so we know what works

Is 1 on 1 personal training more effective for weight loss?

We believe that 1-on-1 support is the best and most effective way to get results. Investing in yourself and being accountable to someone who cares deeply about your progress is an immense driver for motivation

Will Fitness Lab give me a nutrition / diet plan to help?

All new clients are offered a free nutritional consultation – a full hour where you and your trainer can dig deep into what is currently holding you back from achieving your goals. We’ll discuss your current dietary habits and suggest what is good, what changes can be made and what action you can take today to improve your diet.

Giving you a day-by-day diet plan is beyond our scope of expertise as personal trainers, however we will offer as much support as we can when it comes to making the best choices to support your goals. Depending on what your goal is, we can for example provide you with some examples of a day of meals that fit in with your goals. As part of the package, once you get started, your trainer will start a routine of regular check-ins to make sure you stay “on-track”
