What Will Your Next 20 Years Look Like?

Some of what we accept as ‘normal’ ageing is actually preventable decline.

The Default Path(Doing Nothing)

Accepting Passive Decline

  • Progressive loss of daily energy & strength
  • Joint stiffness, caution, & fear of injury
  • A shrinking world of physical limitations
  • Relying on reactive medicine later in life

The Longevity Path(Taking Control)

Building Proactive Resilience

  • Restored vitality, muscle, & metabolic energy
  • Guided, joint-friendly strength progression
  • The physical confidence to travel, play, & live freely
  • Protecting your long-term independence & healthspan

At Longevity, we help you take control of your health through strength training, nutrition, sleep, metabolic health testing, coaching and measurable progress.

Why strength matters

Strength is not just exercise. It’s the greatest investment in your health.

Muscle is metabolic currency. It is one of the most powerful interventions available for long-term health, balance, and vitality.

Metabolic Health

Joint & Bone Defence

Protects joints, reduces pain, and builds natural balance to prevent falls.

Daily Independence

The physical foundation to keep travelling, playing with family, and living active lives.

Deep body insights meets guided strength training

We take the guesswork out of getting older using three tailored pillars:

Precision Health Insights

Simple, comprehensive diagnostic testing (metabolic rate, biological age, visceral fat) to show you exactly what is happening inside your body, taking the guesswork out of your health.

Automated Guided Strength Training

Specialised equipment that automatically adapts resistance dynamically to your capability. It builds maximum strength safely with zero high-impact stress on your joints.

A Welcoming, Structured Environment

No wandering around wondering what to do or feeling out of place. Enjoy a clear, step-by-step routine in a supportive studio setting with our team on hand to help.

Members don’t just feel younger. We measure it.

What our members say

Rated 4.8 out of 5 on Google

Small, specialist health studio with a focus on helping clients build their strength and fitness to reduce their bio age . It's an incredibly friendly and welcoming environment where the coaches have time to spend with members, understand their goals and advise on the right mix of exercise to deliver them. The classes are small so you get great interaction with the coaches and the recently introduced education sessions have been interesting too. Highly recommended for those who want to age younger

— Clare, via Google

Best place ever to age younger! Great people working here and really good equipment. Can't recommend it highly enough. Join - you won't regret it!

— Julie, via Google

Joining Longevity was the best fitness decision I've made. After COVID, I struggled to start exercising and felt intimidated by traditional gyms. However, after discovering Longevity on Instagram, I decided to try the induction—expecting not to join. I was wrong. This gym is truly unique. Neil and the team offer exceptional support, and the bio age assessment was eye-opening. The tailored training plan and interactive machines keep me motivated, and the app helps track my progress. Longevity is perfect for anyone unsure of where to start their fitness journey. The atmosphere is welcoming, and you're never left to figure things out on your own. Highly recommended! 😊

If you want to improve your overall health, lose weight or just increase your strength and fitness levels I can highly recommend Longevity Gym at Windmill Hill. It has modern equipment which is tailored to your exact needs and is easy to use. There are fitness trainers there all the time to help you achieve your goals and answer any questions you may have. You get regular assessments to ensure you are progressing towards your goals and it has a very friendly environment. I particularly like going there as it is tailored more towards an older age group.

— Fiona, via Google

A small gym with knowledgeable trainers. The equipment gives you the complete workout. I especially like the fact that the programme changes every 6 sessions so that you continually progress. I also take part in the Bio Age assessments which help with understanding your body and keeping it young initially my bio age was older than I actually was but now I am 6 years younger after 12 weeks.

— Linda, via Google

Well equipped and friendly gym. Staff very knowledgeable and helpful.

— Mike, via Google

Small friendly place to work out. Doesn't take too long to work your way around the machines in the circuit. Plenty of free parking.
