Hardgainer before and after: 2002 and 2025

The first photo is from 2002. I had been training since 1999, nobody took progress photos back then.

The iron does not lie.

How I gained weight, in three chapters

011999, Wiener Neudorf

My body had an engine and no chassis.

From my book „Warum du nicht zunimmst“ (German)

Strength training grabbed me from day one. I wanted to look muscular, not just thin. At 16 the scale showed 49.3 kg. I had plenty of endurance, strength was missing.

02The years after

Complicated plans are often just camouflage for a lack of consistency.

From my book „Warum du nicht zunimmst“ (German)

Magazine plans with 20 sets of biceps did nothing. With two training partners, four exercises were left: squat, deadlift, pull-ups, dips. Against all advice. The weights went up, so did the scale. Today SDPUD is available as a template.

03Dec 2023 to Apr 2025

Why was I steering other companies with data and my own body with hope?

From my book „Warum du nicht zunimmst“ (German)

In my early 40s I did what I do in controlling every day: measure, weekly average instead of the daily scale. From 65.91 kg to 75.52 kg in 16 months. This exact build-up is what made me found Hardgainer Performance Nutrition®.

Patience was never standing still. Patience was the method.

Common questions about the deep dive

Why do you show numbers and photos so openly?

Because hardgainers do not need fairy tales. Building up is often slow, unspectacular and sometimes messy. Numbers, photos and context show what really happens and how to steer it.

Why is the first photo from 2002 if training started in 1999?

Because in 1999 nobody took progress photos. Training started in 1999 in Wiener Neudorf, the first photo was taken about three years later. The progress before that is real, it is just not on camera.

What is SDPUD and where does it come from?

A training protocol I developed with coaches from BBSzene out of the Heavy Duty and Super Slow principles of Mike Mentzer. Not a system copied from someone else, but adjusted until it worked for hardgainers. Today SDPUD is available as a free workout plan template.

Why does your weight drop at times?

Because real curves have phases: build-up, peak, reset. Stress, daily movement, sleep and deliberately managing body fat move the scale. What matters is not that it always goes up, but that you know why something happens and how to correct it.
