The Flexed Biceps emoji is most commonly used when a person wants to show off their physical prowess. In terms of showing off physicality, you could simply use the emoji in a comment under your post or selfie to highlight said physical fitness. You can also use the muscle emoji to boast about a successful (or upcoming) physical activity; you will most likely need some context to give the emoji meaning however. For example, you have just done a run and want to inspire your out of shape friends. You could say something like: Just did a 10k run 💪💪 While this emoji is certainly applicable to anything involving exercise - you can also used the flexed arm when you want to show off an impressive result or achievement; as if you’re showing off the ‘guns’. Let’s say you applied for a job and were notified that you were successful. You could message your friends something like: You know that job I went for? Start on Monday 💪

The Flexed Bicep emoji was added in Emoji 1.0 and was approved as part of Unicode 6.0 in 2010.
