MiniMax H3 Max Turbo makes a 5-second clip in about two minutes. Download the MP4 and share it.
Ideas and uses
The muscle growth effect
The AI Muscle Generator takes one photo of an adult and makes a 5-second clip where the shoulders and arms grow while the face, clothes and background stay the same. Pick athletic for a lean, toned result, bodybuilder for a big result, anime power-up for an energy-charged look, or gentle gains for a small, realistic change.
People use it for gym humor, before and after jokes and power-up clips for streams. Each clip is made with MiniMax H3 Max Turbo at 768P.
How to get a good result
- Upper body in frame: the shoulders and arms must be visible.
- Fitted clothing: a t-shirt or tank top shows the change best. Loose clothing hides it.
- Face the camera: a straight or slightly angled pose gives the steadiest face.
- Simple background: the background stays the same, so a plain one keeps the focus on the person.

Frequently asked questions
Is the AI muscle generator free?
You can try it free. Sign up with an email address and you get 40 free trial credits. On the trial a clip is made at 480P for 31 credits and carries a small watermark. With a plan, a 5-second clip at 768P costs 50 credits.
What photo works best?
One adult, facing the camera, framed from the waist or knees up, in a fitted top. The growth happens in the shoulders and arms, so keep them in the frame and not hidden behind objects.
Does the face stay the same?
The model is told to keep the same face, clothes and background. Small changes can still happen, most often with the bodybuilder look.
Is there nudity?
No. The person keeps their clothes on. The tool is for photos of adults only.
Can I use photos of other people?
Only photos you have the right to use, and only with the consent of the person in them.
Is my photo stored?
Your uploaded photo is deleted from our server within 24 hours. To make the video, the photo is sent to our AI provider, fal, which keeps its own copy under its own retention rules.
