Flex on 'em. The Flex leggings are back on Friday! To celebrate the return of our four current colours (Lilac, light grey, turquoise and black), we are giving three lucky members of the Gymshark Family the chance to win a pair. All you need to do is let us know your favourite Flex legging colour below. You have 24 hours! Don't keep the news to yourself 👀 Good luck! @gymsharkwomen #Gymshark
