Powerlifting · Squat · Bench Press · Deadlift

We make elite training
accessible to everyone.

Imagine standing in front of a barbell in twelve weeks with a weight you think is impossible today – and lifting it. And in a year, standing where you never dared to dream. Not through a miracle. But because an intelligent system showed you every single step of the way.

What sports science and federations say about us

How Moserab works

One system for your entire journey

  1. Enter your maxes

    Age, body weight and your best lifts. Moserab turns them into goals and a twelve-week plan.

  2. Train with Rab

    Before every session your AI coach asks how you feel. The plan adapts, but only with your approval.

  3. Film it and get better

    A phone video is enough: the technique analysis measures every rep and tells you what to change.

Mission

Discipline and strength can be practised – day by day, set by set. But a person's greatest strength doesn't show at the barbell. It shows in how they make the world kinder.

We believe the true task of every person is to reach a higher spiritual level. The body is not an obstacle on that path – it is the tool.

That is where our system comes in. It corrects your body and with it the way your soul is connected to it. Every set at the barbell becomes a step on your inner path.

Questions

What athletes ask us

What is Moserab?

Moserab is a powerlifting app for squat, bench press and deadlift. It turns your maxes into an adaptive twelve-week training plan, guides you through every session with the AI coach Rab and analyses your technique from a phone video. Moserab is available as a web app in your browser; the apps for iPhone and Android are coming soon.

Does the app change my plan without asking me?

No. Every change to load, sets or exercises appears as a card with a reason. You accept or decline. What you decline stays as planned – and the decision is recorded.

What happens if I progress faster than planned?

After every set the app calculates your current max from weight and reps. If it is more than ten percent above your goal, Rab asks whether you want to raise it. If you say yes, your max becomes the new goal and upcoming sessions for that lift get heavier in the same ratio. If you say no, the plan stays as it is.

What happens with pain or illness?

You log pain with location and intensity. Up to 3 you keep training, from 4 the load is reduced, from 6 the rule engine swaps the exercise for a low-pain alternative from the catalogue. With fever, chest pain or shortness of breath, training is locked. Moserab does not diagnose or treat anything – if symptoms persist, Rab refers you to a professional.

What data does the app need?

To start: age, sex, body weight, height and your maxes in the three lifts. Optional before each session: sleep, how you feel, pain, health values. The rule engine works with whatever is there.

Who is behind Moserab?

Moserab was developed by the von Lemberg family: Dr. Tatjana von Lemberg, three-time IPF World Champion, Yurij von Lemberg, two-time World Champion, and Edwin von Lemberg, German youth bench press record holder. Their competition results are publicly available on OpenPowerlifting.

How does the technique analysis work?

Film a set with your phone, from the side or the front, and upload it. The analysis tracks the plate and your skeleton, measures speed, path, angles and symmetry and checks the finding rules. A few minutes later the report is ready with two overlay videos. Six analyses per month are included; more come in packs of five.

Where does my data go?

Training and health data are special categories of data. Rab and the technique analysis only run with your explicit consent, which you can withdraw at any time. Nothing sent to the language model contains your name or email; the analysis only knows you by a pseudonym. Deletion reaches all the way into the video.

Do I have to train six times a week?

The plan is dense: three lifts spread across the week, with deload weeks 5 and 9. If you manage less on a given day, you tick off less – the plan stays in place and the rule engine takes it into account at the next check-in.

Is there an app for iPhone and Android?

Coming soon. Today Moserab runs as a web app in your browser – on your phone, tablet and computer. The apps for iPhone (App Store) and Android (Google Play) will follow; they share the same account, the same data and the same plan.

Diagnostics and plan

As you get stronger, your plan grows with you.

To start, you enter your age, sex, body weight and your maxes in squat, bench press and deadlift. Moserab turns them into goals for twelve weeks, with deload weeks 5 and 9 and a max test in week 12. Then the next cycle begins.

Not every cycle goes to plan – sometimes it goes better. After every set the app calculates your current max from weight and reps. If it is more than ten percent above your goal, Rab asks whether you want to raise it.

If you say yes, the max you reached becomes your new goal and all upcoming sessions for that lift grow in the same ratio. If you say no, everything stays as it was.

  • Measured on your own sets.
  • From ten percent above your goal.
  • You decide whether it goes higher.
You're ahead of plan
Bench press goal: 100 kg → 116.5 kg
You just pressed 100 kg × 5. That equals a max of 116.5 kg – more than ten percent above your goal. If you like, we raise the goal and adjust upcoming sessions.

Training day

One screen for the whole day.

“Today” shows everything the day needs: Rab asks how you feel at the start, your exercises sit below, and at the end he asks again. Questions expand in place and collapse into a single line once saved – you never leave the screen.

1

At the start

“How do you feel today? Tell me before you start.”

  • Stress, motivation, soreness, sleep
  • Pain, with where it hurts
  • Blood pressure, pulse, weight – from the health app or by hand
  • If something needs to change, the card appears right below – otherwise “Plan confirmed”.
2

Training

“Start set 1”

  • Adjust weight, sets and reps and tick them off
  • Effort 6–10 and pain 0–10 per set
  • Rest with voice cue: “Rest over, set 3, 85 kilos”
  • Pain from 4: the card appears where you are – at the bar.
3

Wrap-up

“Done – how do you feel now?”

  • Well-being 1–5 and pain after training
  • Sets, volume, duration – calculated, not estimated
  • Journal note, health values over time
  • Finally: what was decided today.

AI coach Rab

The rules decide. Rab explains.

Rab is your AI coach. He asks how you feel before and after training, answers questions about your plan and the app, reads aloud and listens – in English, German and Ukrainian.

When the rule engine suggests a change, Rab presents it to you in the first person, without jargon – and he never comes up with a number of his own. You accept, decline or ask “Why?”. Declined means declined; Rab says “Got it.” and remembers.

  • No change without your approval.
  • Every change is visible in the plan.
  • Rab explains, but never invents a number.
Change to your plan
Today 2 instead of 3 sets per main lift
You slept 5 hours and reported soreness 3. Here's how we work: with little sleep and heavy legs we drop one set – the load stays so your technique stays.
AcceptDeclineWhy?
Rab
I've looked at what you told me. If you accept, the new number goes straight into your plan – and tomorrow we check in again.

More cards: substitute exercise for pain in one area · technique session when readiness is very low · reduction on request (“reduce today by 20 percent”) · increase after a strong set.

Rule engine

Twenty rules read what you tell us.

Less than six hours of sleep, soreness, stress, pain in one area, a set that was harder than planned, a competition in seven days: your input becomes a suggestion with a number and a reason. Rab presents it, you decide.

Findings from the technique analysis feed in too: a critical technique finding lowers the load in the next session. With signs of illness there is no discussion – training is locked until you report back healthy.

Pain per set, 0 to 10

0–3You keep training as planned.
from 4The load is lowered; after two sets Rab asks again.
from 6The exercise is swapped for a low-pain alternative from the catalogue.
FeverFever, chest pain or shortness of breath: training locked.

Moserab does not diagnose or treat anything – if symptoms persist, Rab refers you to a professional.

Technique analysis

Film a set. Read what your bar did.

One phone video, from the side or the front. The analysis tracks the plate and your skeleton, measures speed, path, angles and symmetry and checks 47 finding rules – each with severity, affected reps and a recommendation.

The report is written in plain language and can be read aloud. Findings feed into the rule engine: a critical technique finding lowers the load in the next session.

Nutrition

Your needs are calculated in the background.

The app already knows your age, sex, height and weight. From that come your calorie needs for training and rest days and a protein goal that rises with the training phase: 1.5 grams per kilo in the first weeks, 2.4 in the heaviest. You log what you ate by photo, barcode or search – every estimate is a suggestion you can correct.
