You can say no
"I can't today": ALVIA instantly offers an alternative — shorter or gentler.
The hard part isn't the workout — it's deciding.
I decide which session you do today.
Every day, ALVIA reads your form — sleep, energy, drive — and calls it: one session, not a list. You stay in control: start it, adjust it, or say "not today."

Every evening, the same question: what do I do tomorrow?
Too tired? Enough time? Worried about pushing that sore knee? Faced with the doubt, you put it off — and tomorrow it starts again. The real barrier to consistency is neither time nor motivation: it's the decision. ALVIA takes it for you, every day.
How it works
- 01
Tell it how you feel
Thirty seconds when you open the app: sleep, energy, any discomfort. That's it.
- 02
ALVIA decides
The engine weighs your signals, the weather and your training load. It chooses — and it tells you why.
- 03
You follow the session
Guided, timed, no equipment — at home, outdoors or on a break at work. Whenever suits you, not just in the morning.
ALVIA calls it. You stay in control.
ALVIA decides to spare you the overthinking — not to take over for good.
You see why
"Why this session?" opens the reasoning: which signals weighed in, and how.
You steer what's next
Your feedback after each session recalibrates the next decisions. The further you go, the more they look like you.
Why this isn't one more fitness app
500 sessions, yours to pick from. The result: one more thing to decide, every day.
Week 3, day 2: the same session, even if you slept four hours. Your body isn't a schedule.
Ideal — but €50–80 a session, and never around the evening you're wavering.
One decision a day, set to your real state. Free in beta, there the moment you open the app.
What ALVIA listens to before deciding
Your sleep
A rough night changes the session.
Your energy
Wiped out? Recovery. On form? Let's make the most of it.
Your time
Fifteen minutes or an hour: the session fits your window.
Your signals
A twinge? We train around it, never on it. A pain that settles in? ALVIA eases off — and says so.
Weather and air
Driving rain or a pollution peak: indoor session.
Your load
Too many hard days in a row? ALVIA calls for rest.
Four families of sessions. Only one that counts: today's.
Endurance
Brisk walking, easy jogging. To get moving again.
Intervals
Short bursts, sustained intensity. For the days you're on form.
Strength
Bodyweight, no equipment. To build real strength.
Mobility & recovery
Stretching, breathing, gentle core work. To ease off.

Léa, 27
Motivated in waves, between two deadlines.
Tonight: 20 gentle minutes — she slept 5 hours, ALVIA doesn't push.
Marc, 42
Getting back into it, no fuss.
Today: 25 min of easy endurance — three weeks off, so we restart below the threshold.
Sophie, 47
Staying active without getting hurt.
Sensitive knee: ALVIA keeps her upper body active, never the area that bothers her.
Jacques, 58
On form for the long run, at his own pace.
Great-form day: strength work — mobility on the other days.
Trust comes first
Behind the decision, a conviction — and real caution.
Regular exercise should never be a mental burden.
ALVIA is led by Emmanuel Cardi: a trail and cycling practitioner, fifteen years telling stories on film. The engine he's building doesn't chase performance at any cost — it decides the right session, and it protects.

Caution, always on
Discomfort, comeback, overload, a rough night: caution is always on, never optional.
Frequently asked questions
Does ALVIA replace a health professional?
No. ALVIA is a training decision aid, a non-medical wellness tool. It never replaces a caregiver's advice.
When is it better not to train?
Some signs mean stop, not adapt: sharp pain, dizziness, tightness in the chest, fever. In those cases, don't train — rest, and talk to a caregiver. ALVIA can adapt around a mild discomfort; a genuine pain is for you and a health professional to judge.
Do I need any equipment?
None. Every session is bodyweight, at home or outdoors.
What if I haven't done any sport in years?
That's exactly why ALVIA exists. The comeback is gradual and the engine will never offer a session above your form for the day.
