A warm, softly lit modern home gym or sunlit studio, photographed in a clean editorial style. In the center-right of the frame, a silver-haired woman in her mid-60s with a calm, confident expression grips a matte black kettlebell at hip height. She wears a fitted sage-green athletic top and charcoal leggings. Her forearms and shoulders show lean, defined strength rather than bulk. Beside her, slightly out of focus, a man in his late 60s with short white hair and a trim beard performs a controlled bodyweight plank on a pale oak floor.

In the foreground on the left, a minimalist wooden tray holds two small ceramic bowls. One contains fine white powder and the other holds a few cream-colored capsules. Next to them sit a glass of water with a lemon slice and a folded linen towel. A subtle scatter of powder dusts the tray. The foreground is shot with shallow depth of field and a creamy bokeh falloff.

Behind them, tall windows pour in golden morning light, with long soft shadows across the floor. A potted fiddle-leaf fig and a stacked set of pastel-toned dumbbells on a low wooden shelf add texture. The wall is warm off-white plaster with a hint of terracotta in the corner.

The palette is muted and modern: sage green, warm cream, soft terracotta, natural oak, and charcoal, with gentle highlights. The mood is quietly optimistic, focused, and grounded, suggesting strength, vitality, and measured scientific curiosity. The composition leaves clean negative space in the upper-left for a headline overlay. The look is a high-end wellness magazine cover with natural film-like grain, soft contrast, and crisp detail on the hands and kettlebell. There is no text, no logos, and no futuristic elements, only authentic, aspirational realism.

Creatine + HMB maken 60-plussers sterker in zes weken, niet groter

BY DR. GYMBRO ·

In een dubbelblinde crossover‑studie met 30 actieve ouderen leverde een creatine‑+‑HMB‑stack binnen zes weken een duidelijke krachttoename, terwijl de spiermassacijfers nauwelijks veranderden. De onderzoekers vonden verbeteringen in beenspieren, rug, armen, bovenlichaam‑ en core‑uithoudingsvermogen. Regressie‑analyses suggereren dat de winst grotendeels onafhankelijk was van spiergroei, wat wijst op een neuromusculair effect. Let wel: de onderzoeksperiode was kort, de groep klein en de lichaamssamenstelling werd gemeten met BIA. Hieronder lees je wat de studie wel en niet aantoonde en hoe je de resultaten moet interpreteren.

A wide, landscape editorial photograph with a modern wellness-journal feel. In the foreground, a clear glass vial of pale amber liquid sits on a matte white stone surface, with a small dropper beside it and a few droplets catching soft light. A slim brushed-steel measuring spoon and a minimalist notebook with handwritten dose calculations in pencil rest nearby. The numbers are blurred and unreadable.

In the softly blurred background, a bright, airy modern gym with large windows and morning light. A fit man in his thirties, in a charcoal athletic shirt, is mid-stride on a treadmill in profile, with a gentle sheen of sweat and a focused expression. Behind him, a wooden plyo box, a kettlebell, and a rope are arranged neatly, suggesting functional training.

The palette is calm and refined: warm cream, soft sage green, muted terracotta, and touches of deep navy. Natural golden side-light makes long, gentle shadows. Shallow depth of field with a crisp foreground and creamy bokeh. Clean composition with negative space on the left third for a title overlay. Premium magazine photography, subtle film grain, realistic textures, no text or logos, and no futuristic or digital elements.

HMB Verbetert Cardiovasculaire Fitness, Niet Kracht, in Nieuwe 2026‑Studie

BY DR. GYMBRO ·

HMB wordt voornamelijk gepromoot als middel om spiermassa te behouden en kracht op te bouwen, maar een nieuw drievoudig blind onderzoek toonde iets anders. Bij 90 mannen leidde een hoge, op de lichaamssamenstelling afgestemde dosis vloeibare HMB in combinatie met high‑intensity functional training (HIFT) tot een grotere VO2max en verbeterde drempelwaarden ten opzichte van placebo. Het effect was duidelijker bij getrainde mannen, terwijl de isometrische beenspieren ongewijzigd bleven. Hieronder vind je de doseringsberekening, een vergelijking met de standaarddosis van 3 g en voor wie dit mogelijk relevant is.
