Arm emojis bring surprising versatility to texts — from flexing after a workout 💪🔥 to waving hello 👋 in group chats. Use 💪 when celebrating small wins, or 🤚 when you want to interrupt a conversation playfully. The raised hand and biceps combos work well in casual DMs and even in work Slack threads to keep things light and human. They show motion and attitude without saying a word.
