I've seen this for a long time now but have never find an answer to this. Can someone explain to me why football players and coaching staff flex their arm muscles before taking the field? Is it some code for like go strong? Kick some butt?
...it is non-verbal code, for (quickly) relaying an instruction to the players on the field, but because it's code it will mean different things to different teams..a specific formation, a series of plays, a set of predetermined assignments, etc.
The signs and signals on the sidelines of professional sports has always fascinated me. I was at the Argos game on Saturday, and a coaching assistant on Edmonton's sideline was occasionally holding up a sign of the character Tails from the the Sonic The Hedgehog video game series. Totally baffling; I couldn't figure out the pattern.
