In the video, a man is flexing his bicep in a room. The man is wearing a green shirt and has a muscular build. The room appears to be an office or workspace, with a woman sitting at a desk in the background. The man's bicep is well-defined and he flexes it several times to show off his muscle. The woman in the background seems to be focused on her work and does not pay attention to the man's actions. The lighting in the room is bright, and there are shelves with various items in the background.
