A sun-lit editorial still life on a pale oak gym bench: a loaded barbell rests on a rack just above it, chalk dust drifting in the air. In the foreground sits a small ceramic bowl of roasted beets, some sliced to show their deep magenta rings, with a few whole beets still wearing their leafy burgundy stems. Next to the bowl is a matte white supplement tub with a minimal label, a wooden scoop of fine white powder, and a clear glass of water catching soft highlights. A slim notebook lies open beside them with a simple hand-drawn bar graph and a pen, suggesting data and analysis without any readable text. Behind the bench, a softly blurred minimalist training space: raw concrete wall, tall window with warm morning light, a rack of black dumbbells fading into bokeh. The palette is earthy and modern: beet magenta, warm cream, charcoal, brushed steel, and touches of sage green from the beet leaves. Soft directional light from the left creates long gentle shadows and a slight film-grain texture. Shallow depth of field keeps the beets and powder tack sharp. The composition is wide and balanced, with negative space on the right for headline overlay. The overall feel is a clean, contemporary health and fitness journal photograph, warm and tactile, with an understated scientific tone.

Betaïne verhoogt bench‑throw power met ongeveer 16 % in 14 dagen

BY DR. GYMBRO ·

Twee weken betaine, een verbinding uit bieten die ook als TMG wordt verkocht, leverden een toename van circa 16 % in bench‑throw power op de eerste dag van een intensief testblok bij weerstandstraining. Een gerandomiseerde, dubbel‑blinde crossover‑studie toonde bovendien hogere isometrische bench‑presskrachten, met een kleinere winst in verticale sprongkracht en isometrische squat‑kracht. Herhalingen en sprong‑squat‑kracht bleven echter gelijk, en de studie betrof slechts 12 mannen. Hieronder de resultaten, de gebruikte dosis en wat sporters er wel én niet van moeten afleiden.
