There’s only one way to experience Foundry – give it a go.

Our 21 Day Challenge lets you experience our training programmes, feel what it’s like to be part of our community and work alongside our professional coaching team to get the best from every session.


Each month, we make 20 places available in each of our gyms, to allow people to
experience our Small-Group Personal Training and uplifting community spirit.

Join us next month and you’ll see first-hand how our unique sessions build
confidence, transform your motivation and inspire your fitness journey

6 x small-group personal training sessions (50mins)

Our SGPT classes combine high-quality coaching that focusses on what you really need to get ahead and get results, with the added motivation of a fun class dynamic.

Every fitness journey needs a starting point. This is yours. We take time to assess your individual mobility, agility and fitness. Then, develop a programme to help you excel.

Drop into our classes whenever you like, for fad-free, feel-good training that ticks all the boxes. Work with the best coaches in London and let the community vibe take you further.

Discover the best way to power your fitness journey and how to transform your health and wellbeing, in and out of the gym.

Our Challenge FAQs

What is included in the 21 Day Challenge?

We want to give you the best possible experience when you join, and make you feel exactly like a full time member. To get you off to the perfect start, see where you’re at, and discuss any specific goals or concerns, we’ll give you a personalised evaluation with one of our personal trainers.

This includes a movement screening and an optional body composition measurement. It will also give us an opportunity to get to know you and help you get the most out of your training.

You can then look forward to 6x SGPT sessions, unlimited group classes, a warm welcome to the Foundry collective and our fitness community.

Don’t we all! We totally understand and appreciate that you may be carrying some previous injury history, so don’t worry. We can discuss, assess and make a plan to manage this together.

Our aim is to make sure you feel comfortable and confident, even if that means we need to proactively adapt some movements, or add some corrective exercise.

Perfect for us! We absolutely love being able to support our member community, no matter what level or experience you have. You may have not been keen on sports at school, or maybe you’ve taken up fitness later in life?

We’re firm believers that “age ain’t nothing but a number”, and we’re here to support your journey.

Not every day needs to be a training day. We believe in a sustainable approach to training, and rest days are truly a big part of the process.

If you sign up to the challenge and know that you will be unavailable for a portion of the 21 days, let us know, and we may be able to extend it for you – so you can still get the most out of your experience.

Hell no! What does strong really mean? Foundry is not just about building physical strength; it’s about mental strength too – the strength to start a challenge, the strength to turn up, the strength not to quit when the going gets tough, the strength to tell your coach to do one when he asks for two more reps!!!

After successfully completing a new workout routine over your 21 days, you’ll have the opportunity to continue your new found momentum and motivation, and become a fully-fledged member of the Foundry collective.

We’re always happy to see our community go from strength to strength (quite literally!). and would love you to join us.

Our Small-Group Personal Training sessions (SGPT) are 50 minutes, and our group classes are 45 minutes. Simple, yet effective doses of training.

We hold ourselves accountable to delivering within those times, as we know how important it is for you to manage your schedules around the gym.

You’ll have full access to toilets, changing rooms, showers, shower gels, shampoo and conditioner. We also have hairdryers (Dysons no less!), straighteners and some other toiletries for you to use.

Shower towels are available free of charge (one per member), and sweat towels are also available in reception for you to take into your session. Just pop these in our towel bins at the end of your workout.
