Why it worked
The video leverages high-quality, aspirational fitness content to naturally feature the brand, making the clothing look desirable through the creator's physique.
Product placement
Gymshark: (a) it ACTS — the creator is wearing a Gymshark branded sports bra, which is the focus of the video as she showcases her physique and the fit of the clothing. Removing it would change the video as it is a product showcase.
