Clothes in size S.And they still hang off you.

Summer. And you know exactly how that shirt sits on you.

And someone tells you again:Just eat more.

You are not undisciplined.
You are a hardgainer.

And that is not bad luck. It is an explanation.

I was under 50 kg.75 today. It took a long time to understand why.

What this is

We build a system, not motivation

Hardgainer Performance Nutrition® is a specialised brand for people who build body weight and muscle only with difficulty, despite training, discipline and a small appetite. Not a general fitness portal, a place for this one specific starting position.

What you get here: free calculators and planners, six core topics from training to mindset, a glossary with more than sixty terms, twenty myths taken apart, and the first Hardgainer Supplements of our own, once they meet our standard.

Built by Christian Schönbauer. Under 50 kg at 16, 75 today. I was a hardgainer myself.

The explanation

Why nothing happens to you

Your daily life burns more than you think.
You are full before enough went in.
Your training costs more than it builds.

Your daily life burns more than you think

Fidgeting, walking, standing, restlessness. That runs under NEAT and is often the largest single item in a hardgainer's TDEE. Add exercise activity on top of it. Together they explain why your maintenance calories sit higher than any standard calculator says. Deeper in the deep dive on calorie needs.

You are full before enough went in

Appetite is not a character trait, it is a signalling system built on ghrelin and leptin. Eat high volume and low energy and you end up full without gaining. The lever is energy density and distribution, not willpower. Practical side in the meal plan for a low appetite.

Your training costs more than it builds

Between MEV and MRV lies the range where training works. Above it every extra set turns into junk volume: fatigue without growth. You steer that with RIR and the SFR. Numbers in the deep dive on workout volume.

Not bad genetics. An energy gap you can steer.

The tools

Three calculators, one system

Free, no signup, straight in the browser. They build on each other: first the number, then the plate, then the plan.

Common questions

What hardgainers ask most

What is a hardgainer?

A hardgainer gains weight only with difficulty despite training and eating. Common reasons: high energy expenditure through NEAT, low appetite and the wrong training dose. The term describes a structural energy gap, not a willpower problem. Full explanation.

Where do I start today?

Take the test, then the calorie calculator, then 10 to 14 days of trend weight, then meal plan and workout plan. One variable at a time.

How do I find my starting calories?

Start at your maintenance calories, watch your weight over 10 to 14 days, then adjust. Fastest with the calorie calculator.

How fast should I gain?

Controlled. Steer by the weekly average and adjust in small steps. Use rate of gain as your guardrail, not the daily number on the scale.

How much protein do I need as a hardgainer?

Spread protein across the day instead of packing it into one meal. What matters is that every serving hits the leucine threshold. Beyond that, more in the same meal adds little.

How often should I train?

Often enough to land between MEV and MRV. More sessions only help as long as you recover from them. Details in the deep dive on workout volume.

What do I get with Hardgainer Pro?

Hardgainer Pro unlocks the Pro versions of all three calculators, including saving, PDF export and advanced settings. One-time payment, no subscription.

Do I need supplements to gain weight?

Supplements can support you, but they never replace the basics: enough calories, enough protein, clean training and recovery.

When are the Hardgainer Performance Nutrition® supplements coming?
