The model looked strong and powerful in a teaser for a new campaign she hashtagged "StrengthBeyondSize."
Graham is glowing and working up a sweat as she boxes in the video.
"I can't stop. I won't stop. I am an overcomer. I am Strength. I am Power. I am Determined. #StrengthBeyondSize #BeautyBeyondSize" Graham captioned the Instagram.
The director, Justin Ervin, shared a behind-the-scenes shot on his own Instagram, and Graham commented, "When a power couple makes magic together…"
Trainer Christopher Kadima added another intense photo from the shoot, hinting that the full video is "coming soon."
Graham made history in February as the first size-16 model to land the cover of Sports Illustrated's Swimsuit Issue.
