Training and nutrition · Zürich

A 12-week programme to lose fat and keep your muscle.

You've lost weight before and it came back. Often part of what you lost was muscle, and the scale doesn't show that. Here you train one to one with a coach who studied sport science, Roberta Burla coaches your food, and a scan at the start and at week 12 shows the difference.

What you get

What makes the fat go and the muscle stay.

Most people try to lose fat with a diet and a lot of guessing. The weight goes down, some of it is muscle, and a few months later it's back. Here your coach, your nutrition coach and your scans work from the same numbers.

Training

Learn to train, and keep your muscle

One to one with a coach who studied sport science, who teaches you the basic movements and how to pick the right weight. When you eat less, that training tells your body to keep its muscle. And what you learn stays with you after week 12.

  • Health check and baseline tests in sessions 1 and 2
  • The basic movement patterns, taught step by step in your first 8 sessions
  • You learn how to progress, so you keep getting stronger
Nutrition

Learn to eat for your goal

No strict diet that ends the day you stop. Roberta Burla, MAS ETH in Nutrition and Health, teaches you how much protein you need and what to put on your plate, with simple menus for home and options for eating out. By week 12 you know how to eat for your goal on your own.

  • A 60-minute first consultation
  • Two 45-minute follow-ups
  • Check-ins every two weeks
  • WhatsApp support in between
  • Your plan adjusted as you go

See what you lost in fat and kept in muscle

One body composition scan before you start and one at week 12. Fat and muscle, region by region, including the fat around your organs. We explain both to you in person, side by side.

  • Your starting scan, explained
  • Day-one tests repeated at the end
  • Second scan and side-by-side report at week 12
Week by week

What happens in your 12 weeks.

From your first scan to your second: what you do in training and in food, and what you get from each stage. Scroll through it, or tap a stage.

Week 0 · Before the first lift

You see where you really start.

Most people only know their weight. Your first scan shows fat and muscle, region by region, including the fat around your organs. We sit down with you and explain every number. Then we set a goal you can measure and ask you four questions about what success and failure would mean for you.

Weeks 1 to 4 · Learn the lifts

You learn to lift well, so you can push hard later.

The first sessions include a health check and simple tests that give us your baseline. Then you learn the basic movement patterns everything heavy is built on: squat, hinge, push and pull. Once your technique holds, your coach runs strength tests to find your starting weights.

Weeks 5 to 8 · Get stronger

You get stronger while you eat less.

This is the heart of the programme. Most people expect to feel weaker on a diet. Here the weights still go up while you eat a little less, and that is the signal your body needs to hold on to its muscle. Same exercises, so we can see your progress clearly. Most weeks your coach adds a rep or a little weight.

Weeks 9 to 12 · Show it

You see how much stronger you are.

Your main lifts take another step up. In the last sessions you repeat the tests from day one, so you can put your numbers side by side. In week 10 we sit down with you and plan what comes after the 12 weeks, so you don't start from zero again.

How often

How often you train changes what you see.

Every session is hard work at your level. The more sessions fit into your 12 weeks, the more your coach has to work with. Pick how often you can come and see what to expect.

How often can you train?

Each column is one week. Each square is one 60-minute session.

How training and nutrition fit together

The scale can't tell fat from muscle.

If you've lost weight and got it back, this is often part of the reason. Food decides whether you lose weight. Training decides what you lose. If part of it is muscle, the weight tends to come back, and the next attempt is harder. That's why the two go together here.

What the scale saysWeight down
What the scan shows you lost
FatMuscle

Part of what you lose is muscle. You end up lighter but softer, and the weight comes back more easily.

Strength training protects your muscle while you eat a little less, so what you lose is mostly fat. Your scan shows you the difference.

Illustration of the principle. Your own numbers come from your scans.
Eat a little less than you burnWith enough protein at every meal, so you stay full and keep your muscle.

Our promise

What we promise, and what we don't.

We promise

You'll know exactly what changed in your fat and your muscle.

Two scans and a written plan between them. Your training and your food are coached, and your tests are repeated. If you come to your sessions and follow the plan, at week 12 you see in numbers what changed in fat, in muscle and in strength.

We don't promise

A number of kilos by a certain date.

Bodies don't work like that, and anyone who promises it is guessing. Where you start, how you sleep and how much stress you carry all play a part. We measure, so neither of us has to guess.

I’m in my fourth month now, going twice a week. I’d never really lifted heavy before, and now I’m genuinely surprised by how much I can do. … We did a [scan] and the results are already showing: I’m losing fat, gaining muscle, clothes fit better, my mood and posture improved. I’m getting great nutrition advice and homework.

Ivana B. · Google review · Sep 2026

I started with Alejandro more than 2 years ago with training 3 days a week and proper nutrition. The changes were very visible already in the first 6 months, with a significant loss in fat and weight increase in muscle.

They keep track of all your progress and can adapt the training to your need. I’ve been going there for a few months now and can see the difference.

Xavier D. · Google review · Oct 2026

The team also guided me with nutrition, calculating my daily calories and macros and helping me track progress using practical tools and apps. Jorge created personalized programs tailored to my goals, which we updated every 6–8 weeks.

Talgat N. · Google review · Oct 2025

I signed up for a trial session at Vault on a lazy Sunday morning, and it turned out to be one of the best decisions. … David is kind, professional, knowledgeable, and genuinely attentive. He pays close attention to how I'm doing and makes every session feel purposeful and encouraging. It's the reason I signed up for a year of twice-weekly training, and I'm excited every time I walk through the door.

Questions

Questions about the 12 weeks

For anyone who wants to lose fat without losing muscle, and wants to see it measured. It's for you if you've lost weight before and it came back, or if you train and don't see much change. Many of our clients are busy professionals, and some had never lifted before. It works best if you can train three times a week, and it works well with two.

No. The first sessions include a health check and simple tests, and you learn the basics before the weights go up. From there, the weights follow what you can do on the day.

Three sessions a week gives your coach the most to work with. Two a week works well too. Once a week also works: the change on your second scan is smaller, so we read it together with your strength numbers.

Yes. The programme includes two scans: one before you start and one at week 12, each explained to you in person. If you only want a scan, you can also book one on its own.

A 60-minute first consultation with Roberta Burla, MAS ETH in Nutrition and Health, two 45-minute follow-ups, check-ins every two weeks and support on WhatsApp in between. Your plan is adjusted as you go, based on how your weeks really look.

No. You don't get a menu for every day of the month. Roberta starts from how you eat now and gives you clear, simple targets, and she explains why they work. That way you can keep going after the 12 weeks without us.

We don't promise a number. It depends on where you start, how often you train, how you eat, sleep and handle stress. What we promise is that you'll know exactly what changed, because we measure it at the start and at week 12.

In most cases, yes. Tell us at your first session. We adapt the exercises and build up the area carefully. If something needs a doctor or a physiotherapist first, we tell you, and we're happy to work with them.

By the end you know what to keep doing with food, and your second scan becomes the starting point of your next block. We plan the next weeks from what your scan and your log show. You decide how you want to continue, with us or on your own.

It depends on how often you train. You find every option on our pricing page, and we go through it with you at your free trial, with no pressure to sign up on the day.
