Big Guy — a park dance with flex poses.
Big Guy sets the subject dancing. The sample opens on a woman with long dark hair, a black crop top, olive cargo trousers and white trainers, standing on a stone path in a sunny park. She moves through a string of arm moves, including a raised, flexed-arm pose, while the camera stays still.
The sample
What happens in the Big Guy sample.
The sample opens on a woman standing on a stone path in a green park, with pine trees, grass and bright sun behind her. She wears a black crop top, loose olive cargo trousers and white trainers. She starts to sway, then raises one arm in a flexed bicep pose while the other arm swings out. More moves follow: hands drawn up near her chest, arms stretched to the sides, a quick hand gesture near her face, and a final raised, flexed arm. Her feet shift and step along the path as she dances.
Her clothes, hair, the path and the park stay the same from start to end, and the camera does not move. Her body size does not visibly change in these frames, even though the effect's name hints at bulking up. What the sample shows is a dance routine built around flex poses. She is framed head to feet throughout, so a full-length photo is the nearest match.

Your photo
Photos that suit it.
One-tap effects have one input. The photo you pick is your creative control.
Head to toe in frame
The sample shows the woman from head to feet the whole time, so a full-length photo matches its framing.
Open space around you
She swings her arms wide and steps along the path, so a photo with clear space on both sides leaves room for the moves.
One person standing
A single dancer stands upright in the sample. A solo, standing photo is the closest starting point.

What does the Big Guy effect do?
A woman in a black crop top and olive cargo trousers dances on a stone path in a sunny park, moving through arm swings and raised, flexed-arm poses.
Does Big Guy make you look more muscular?
Not in the sample. The woman's body size does not visibly change across the frames. What she does is dance on a park path, raising and flexing one arm, swinging her arms out and gesturing with her hands, while her crop top, cargo trousers and the park stay the same. The camera holds still throughout. One photo is all it takes.
