The "💪🏿" emote, or "Flexed Biceps: Dark Skin Tone" emote, is a representation of a flexed bicep muscle with a dark skin tone. It is often used to convey strength, power, and determination in various contexts, such as fitness, sports, and personal achievements. The dark skin tone variant of the emote was introduced in 2016 as part of a larger effort to increase diversity and representation in emoji.
