Story & heritage
Gymshark’s official copy frames Flex High Waisted Leggings as a callout to the “OGs,” tying the product to one of the brand’s long-running gym silhouettes.
The line is positioned for lifters, with “set by set, rep by rep” language on the current product page.
Materials & craft
The page lists physique-shaping shading, sweat-wicking technology, soft-yet-supportive seamless fabric and a branded seamless jacquard waistband.
Materials are listed as 91% nylon and 9% elastane.
How to choose & style
The high waistband is the visual signature, so cropped tanks and sports bras make the Flex identity clearer.
Black is the classic option; charcoal and petrol marl versions highlight the contrast waistband.
