What AI Muscle does
You flex and bulk up on camera into a full bodybuilder: shoulders broaden, arms swell, abs pop and your shirt gives up at the seams.
Flex into a bodybuilder on camera
You flex and your body bulks up on camera into a full bodybuilder physique: broad shoulders, huge arms, a stage-ready pump. A waist-up or full-body photo works best.
Still looks like you
The video opens on your exact photo, so the face, hair, outfit and surroundings carry through the whole effect.
A full transformation in one shot
The change happens on camera in one continuous take, so viewers see the before and the after in the same clip.
