There's nothing to film: our page gives you the shy smile, the sleeve push, the flex, the heart and the hold, complete with the sound. You'll keep your own face, hair, arms and outfit in every second.

Here's what's below:

How to Do the Bicep Heart Pose With Your Own Arms

How to do the bicep heart trend starts with the pose: one flexed arm and your other hand make one heart.

Here's the bicep heart pose, move by move:

1. The flex: bend one arm up at shoulder height with the fist closed by your head.
2. The hook: curl the four fingers of your other hand over against the inside of that wrist, just under the fist.
3. The thumb: rest the thumb of that hand on top of the flexed arm.
4. The heart: the curled fingers and the fist make the two round tops of the heart, and the thumb is its point.

A viewer under one of the videos shared a tip: "put your thumb on your bicep w the arm you aren't flexing i think".

You don't need big arms, since the heart's your own flexed arm and your own curled hand, so any arm makes it.

The Bicep Heart Trend in 7 Seconds, Beat by Beat

A bicep heart trend video runs about 7 seconds in one take, from a shy smile to a held heart.

Here's how our 7-second version plays out:

• The smile (0 to 0.5 seconds): one hand holds your other forearm low in front of you. You give the camera a shy, closed-mouth smile with a slow blink and a little head tilt.
• The sleeve (0.5 to 2.4 seconds): one arm crosses your chest, and that hand pushes the T-shirt sleeve on your other arm up toward the shoulder.
• The flex (2.4 to 3 seconds): your other arm lifts out to the side and bends up, fist closed by your head. The bicep tenses into a curve, right on the beat.
• The heart (3 to 4.2 seconds): the crossing hand rises to the flexed arm and curls. The fingers hook up under the fist and the thumb rests on top of the bicep, so your hand, forearm and fist frame one heart.
• The hold (4.2 to 7 seconds): you keep the heart still with a proud little smile. Your eyes close softly for a moment with a smile and a head tilt, then you look back into the lens to the end.

It's set to the music: the flex lands on a beat of the trend's original sound, and the heart lands on the next.

When people film it themselves, they prop the phone's front camera at chest height and film from the waist up, indoors, in a short-sleeve top. It's one take of about 7 seconds. Before the flex, most push the sleeve of the arm they flex up over the shoulder.

If you'd rather skip filming, add one photo to our Bicep Heart Trend AI generator and press Create.

• A pet or a character: upload a dog, a cat, or a cartoon or game character if you want a playful spin.
