Who to tag

Who to send your bicep heart to

  • Your partner

    The classic: a bicep heart instead of a love letter. Expect one back.

  • Your crush

    Low pressure, high charm. It is a joke and a hint at the same time.

  • Your gym buddy

    Show off a little progress, with love. Bonus points if they reply with a bigger one.

  • The group chat

    Send it as a reaction to good news, or just because. Then wait for the replies.

  • Your mum or dad

    Parents love this one, and they will probably try it back.

  • Yourself

    Self-love counts. A deadpan bicep heart to your followers is a whole genre.
