How to do the bicep heart by hand
- 01
Make a fist and flex
Raise one fist next to your head so the arm bends into a bicep flex. Turn that arm slightly toward the camera.
- 02
Curl the other hand on top
Bring your other hand across your chest. Thumb down along the inside of the bicep, fingers curled over the top of the muscle.
- 03
Close the heart and hold
Your hand and the curve of the flexed arm should make one heart. Hold it for a beat and smile at the camera.
Photo tips for a clean heart
- One person from the waist up, facing the camera.
- Both arms in view and not crossed, hands free.
- Short sleeves or a T-shirt so the bicep and the heart are easy to see.
- Good, even light and a plain background. A vertical photo works best.
The bicep heart AI keeps your own arms. It does not add muscle; the curled hand makes most of the heart.
Add the bicep heart sound on TikTok
