Solo uses one portrait, Duo uses two separate portraits, and Pet adapts the gesture to your animal. ### Choose who makes the heart Each template has its own photo requirements and identity instructions. Duo currently means two people, not an arbitrary crowd. ### Preview the motion Solo has a human motion reference. Couple and Pet each have a dedicated 5-second AI-generated sample, showing two separate arm hearts and a two-paw heart respectively. These samples guide movement; they do not depict customer results. ### Leave room for arms and paws For people, frame the face through the waist with both arms visible. Short sleeves make the gesture easier to read. Avoid crossed arms, hidden hands and strong perspective distortion. For pets, use one clear animal with its face and front legs visible. Fur, markings and species come from your photo; the upright paw gesture is an animated interpretation. ### Output and quality Each request targets a 10-second vertical HD MP4. Your photos provide the identities and a separate pose image guides the gesture directly during video generation. A generation uses 10 credits for any of the three templates. https://bicepheart.dev/#create ## What Is the Bicep Heart Trend? https://bicepheart.dev/bicep-heart-ai-trend A raised arm forms one side of a heart; the other hand closes its shape. The gesture combines a little flex with a friendly expression. ### How the gesture reads Start relaxed and bend one elbow upward. Curl the raised wrist downward, bring the opposite hand across your chest and touch upward-curving fingertips to the downward fingertips. The arms and hands enclose the heart; hold the shape so it can be recognized. The effect does not need oversized muscles. A natural arm size and clear silhouette usually communicate the joke better than an exaggerated body transformation. ### One gesture, three casts Solo keeps the viewer focused on one expression. Duo puts two adults next to each other, with enough space for each to form a separate heart. Pet turns the movement into a stylized paw pose while keeping the animal recognizable. ### Motion reference versus identity The pose guide provides the final gesture. Your uploads supply faces, clothing or animal markings. The studio sends your photos and the separate pose guide together to generate the video, with instructions to borrow the gesture rather than the guide identities. This is a generative video edit, so hands, paws and facial details can vary. It is not a guaranteed frame-by-frame replacement. ### Make the context clear Review the result and label it as AI-generated when sharing. Use photos you are permitted to animate. Add a permitted soundtrack after downloading; the original song is not included. https://bicepheart.dev/how-to-make-bicep-heart-ai-video ## How to Make a Bicep Heart AI Video https://bicepheart.dev/how-to-make-bicep-heart-ai-video Choose Solo, Duo or Pet, upload a photo for every role, select quality and generate once. Review the heart gesture in your saved result before downloading the MP4. ### 1. Choose Solo, Duo or Pet Open the generator and play the motion reference. Solo accepts one adult portrait. Duo has separate Left person and Right person uploads. Pet accepts one photo of your animal. https://bicepheart.dev/#create ### 2. Upload clear photos Use JPG, PNG or WebP up to 10 MB each. Show each human face and both arms; for a pet, include the front legs and recognizable markings. Duo does not require a shared photo. Check the ready counter: one of one for Solo or Pet, two of two for Duo. Replace a photo if it is in the wrong role. ### 3. Choose quality and sign in The studio uses your photos and a separate heart-pose reference to request a 10-second vertical 720p video. Confirm your photo rights and sign in. Each request uses 10 credits. One-time packs cover 1 video for $9.90, 3 for $24.99 or 10 for $69.99. Credits last 180 days. Check your updated balance after payment. ### 4. Submit once and follow the task The app prepares your photos and saves a task. You can stay on the page or return to the same account. Do not submit another request simply because a provider confirmation is delayed. No fixed generation-time benchmark is claimed. Reference length is not processing time. ### 5. Review and download Check the face or pet markings first. Then watch the arms or paws through the entire motion. In Duo, each person should remain in the selected position and form their own heart. Download the completed MP4 from the result panel. https://bicepheart.dev/#create ### Hands, paws and failed tasks A malformed heart: try a clearer photo with visible arms, less foreshortening and no hand obstruction. A drifting identity: avoid distant faces or heavy filters. A pet with human features: use one animal only, clearly framed. Confirmed failed tasks restore reserved credits. A completed but imperfect clip is not a failed task; making another is a separate request. For an unresolved task or payment issue, use account support with its reference. https://bicepheart.dev/settings/tickets ### Music and sharing The original song is not included. Download the MP4 and add music you are permitted to use in an editor. Reference previews are labeled separately from your result. This guide does not claim a measured success rate or present references as newly generated outputs. ## Make a Couple Bicep Heart AI Video https://bicepheart.dev/bicep-heart-ai-couple Two people, two individual hearts. Upload one portrait for the person on the left and another for the person on the right. Each performs the arm-heart gesture independently in the same vertical video. ### See the two-person Bicep Heart movement In this AI-generated sample, a green-shirt performer stands on the left and a lavender-shirt performer stands on the right. Both begin relaxed, raise an arm, then meet their own fingertips above the bicep. They each make a complete heart; they do not combine hands to make one shared heart. The sample is approximately five seconds long. Your requested output is ten seconds, giving the gesture and final hold more room. The sample demonstrates movement and framing. Your two uploaded portraits supply the left and right identities; a separate pose image guides each person’s gesture in the generated video. ### One upload for the left person, one for the right Select Couple in the studio. The Left person slot maps to the left side of the finished video as you view it. The Right person slot maps to the right side. These are screen positions, not a person’s left or right arm. Use a separate photo containing one adult in each slot. You do not need a shared couple photo. Before generating, compare the two thumbnails and replace either photo if you assigned the wrong position. Left person: upload the first adult’s portrait. Right person: upload the second adult’s portrait. Check that the counter shows 2 of 2 photos ready. https://bicepheart.dev/?template=bicep-duo#create ### Photos that leave room for two hearts Choose a clear front-facing or gently angled portrait, ideally framed from the face through the waist. Keep both shoulders and arms visible. Short sleeves and an uncluttered background help the arm silhouette read clearly. Similar camera heights and lighting make the two people easier to place together. Avoid very distant faces, crossed arms, sunglasses that hide the eyes, extreme filters or photos containing several people. You can use two photos taken in different places. ### Create, review and download your couple video Confirm permission to use both portraits, sign in and generate once. The studio requests a 10-second, 9:16 video as an HD MP4 and uses 10 credits. Follow the saved task, then download its completed MP4. Review each face, the left/right placement and both hand shapes through the movement. Hands and identity details can vary in generative video. If the identities appear reversed, check the original slot assignments before deciding whether to make another request. A new render is a separate generation. https://bicepheart.dev/?template=bicep-duo#create ### Couple template questions Can two friends use it? Yes. Couple describes the two-person layout; the two adults do not have to be romantic partners. This template supports exactly two people, not a larger group. Does it include the original meme song? The original recording is not included. Add music you are permitted to use after downloading if you want a specific track. Does the sample guarantee the same result from any photo? No. It demonstrates the intended composition and gesture. Your generated result depends on photo clarity, framing and model output. ## Make a Pet Bicep Heart AI Video https://bicepheart.dev/bicep-heart-ai-pet Give your pet the Bicep Heart treatment: two furry front paws curl together to outline a heart beside the face. Start with one clear pet photo and use the Pet template for this deliberately playful animation. ### Watch the husky paw-heart sample The black-and-white husky starts seated with its front paws down, lifts both front legs and touches its paws to complete the heart opening. Its blue eyes and recognizable coat remain visible as it holds the pose. This is our approximately five-second AI-generated sample. The pose deliberately gives the front legs an expressive, human-like bend while keeping furry paws. It is an animated meme, not a depiction of natural canine movement. Your requested video is ten seconds. ### Choose one clear photo of your pet Upload one animal in the Your pet slot. Keep its face, chest and both front legs visible, with room around the shoulders. A seated, front-facing photo gives the reference movement a useful starting point. Sharp fur markings, visible ears and a well-lit face help distinguish your pet from the husky sample. Avoid a distant animal, a close crop of the face alone, a pet hidden under a blanket or a photo with several animals. JPG, PNG and WebP uploads are supported up to 10 MB. https://bicepheart.dev/?template=bicep-pet#create ### Dogs, cats and recognizable details The Pet instructions preserve the uploaded animal’s species, muzzle, ears, coat pattern and tail, using the reference for movement rather than its husky identity. Dog and cat photos can be submitted; different body shapes can produce different paw silhouettes. The visible sample demonstrates a husky. It does not establish a measured success rate for cats or every breed. For animals with very different anatomy, this front-leg gesture may be less suitable. The intended result retains animal paws instead of adding human fingers. ### Generate your pet’s Bicep Heart video Open Pet, check your uploaded thumbnail, check the 10-second vertical HD format, confirm photo permission and sign in. A request uses 10 credits and targets a ten-second vertical HD MP4. Submit once and follow the saved task. When the result is ready, watch the whole clip. Check the pet’s identity, the number and connection of its legs, and whether both paws finish the heart. Download the MP4 from the result panel after reviewing it. https://bicepheart.dev/?template=bicep-pet#create ### If the paws or markings look wrong A wave instead of a heart: check that you selected Pet and watched the two-paw reference. A body that is hard to read: choose a seated image with both front legs unobstructed. Lost markings: use a sharper, evenly lit photo without a strong filter. A completed clip can still contain imperfect anatomy. Confirmed failed tasks restore the reserved credits; a completed but imperfect clip is a different case. Use account support with the task reference if you need help reviewing an unresolved generation. https://bicepheart.dev/settings/tickets ### Sound and sharing The original meme song is not included. You can add a permitted soundtrack in your editor after downloading. Share the clip as an AI animation. Keep a local copy of the result you want to retain, and use account support for requests to delete uploaded photos or saved results.
