Fans were free to document their progress throughout the challenge. The brand asked the fans to tag the brand using @GymShark and #gymshark66. The winner of the challenge would win a free year-long supply of GymShark goods.


In order to promote the challenge, increase brand awareness and create meaningful engagement on their channel, Gymshark collaborated with 6 influencers on TikTok. All 6 influencers had more followers on TikTok than they had on Instagram and interestingly, 4 of the 6 accounts were operated by twin siblings (twins are extremely popular on TikTok).
