How I lost 18 kg in 3 months
— and why I created KLYN

A few months ago, I no longer recognized myself in the mirror. Not because I'd stopped trying — I had tried everything. Diets, gyms, program PDFs downloaded off the internet. Nothing stuck. After two weeks, I'd give up. Always the same story.

What changed everything was the method I later built into KLYN. And in 3 months, I lost 18 kg. I'll explain exactly how.

Why conventional programs don't work

Most weight-loss programs make the same mistake: they hand you a fixed plan, without accounting for your level, your availability, or what you actually eat. You miss a session, you feel guilty, you quit.

A good fitness program should adapt to you, not the other way around. That's what I understood — and that's the principle I built KLYN on.

Phase 1 · Weeks 1–4

Shape Bodyweight — the first 4 weeks

I started with no equipment at all. No gym, no dumbbells, just my body and some floor space.

The KLYN Shape Bodyweight program is 3 guided sessions a week, progressive. Every movement is explained, every rep counts. The AI coach Maya guides you session after session — she adapts the intensity to your level, not to a generic one.

In the first weeks, I lost around 4 to 5 kg. Mostly thanks to a change I didn't expect: nutrition.

The real secret: nutrition is 70% of the results

I'll be direct: exercise alone isn't enough. It took me a while to accept that.

With KLYN Shape, I followed the nutrition plan included in the app: 28 recipes calibrated over 28 days, with weights, macros, and alternatives if you don't like an ingredient. Breakfast, lunch, dinner — everything was prepared for me.

Phase 2 · Weeks 5–8

Shape Equipment — the next 4 weeks

After a month of bodyweight, I added dumbbells and resistance bands. The program evolves naturally — coach Léna takes over with more intense sessions, focused on sculpting and losing body fat.

This is the stage where the visual transformations become most striking. My body began to reshape: less volume, more tone.

Week 3: the moment I almost quit

I'll be honest. By the third week, the scale hadn't moved in several days. I wanted to give it all up.

What saved me was structure. I had a plan for the next day. A scheduled session. Meals already decided. I didn't have to decide — I just had to follow.

I held on. And in week 4, my body caught up.

The result: −18 kg in 3 months

After 12 weeks, I had lost 18 kg. Not thanks to a miracle, not a pill or an extreme diet. Thanks to a coherent method: progressive training + calibrated nutrition + constant support.

That's exactly the method I built into KLYN.

Why I created KLYN

Throughout my transformation, I wished I'd had an app that truly guided me — not a fixed PDF, not a generic program, but something that adapts to me, that answers my questions at 2 a.m., that encourages me when I want to give up.

KLYN is the tool I didn't have. So I built it.

5 AI coaches (Maya, Léna, Atlas, Onyx, Kaïa), 4 programs (Shape, Build, Military, Mind), nutrition included, AI coach available 24/7. Everything you need for your transformation — in a single app.
