How is this a myth? What is the supposed content of this myth? And the video? Some people throw like girls, then throw even more like girls with their other hand. Then this lady comes up who can throw and is commended for throwing like a man. What?

If you are a man and someone says you throw or run like a girl everyone understands what that means. It means they want to find out if you also fight like a girl.

If you are a girl and you do something like a girl - that doesnt actually merit conversation. Or insult. Ambiguity overload. Could mean anything.

Throwing with your left hand. That has more to do with your favored hand and favored eye than practice and technique. My younger son is right handed but has a dominant left eye. He can hit a target equally well with either hand, same "form". He can probably throw a bit farther with his right hand but not by much. Not so good trying to aim a gun - try holding a weapon in your right hand and aim with your left eye. He shoots like a girl (yes I know there are many girls who can shoot) but he can throw like a man with both hands. For basketball, tennis, ice-hockey, soccer - very useful to be ambidextrous. Probably also skiing, snowboarding, surfing, because you care less about which way you are turning.

Why would you want to take practice and technique out of the equation anyway - throwing like a girl is not just about strength, it´s about attitude and motivation and will to compete. And technique.

And girls very obviously have different techniques to men in sports that rely a lot on strength and aggresivity. Some girls practice with men and apply masculine techniques, others try to find their own way. No one tells Sharapova that she hits the ball like a girl - but that is certainly exactly what she does, compared to Nadal, no insult intended.

Andy Murray now has a female coach, I am sure he will be very careful not to appear to be hitting the ball like a girl.

If you have the same equipment and strength matters you cant help having a different technique.

If all that matters is skill (lets say youre throwing a light ball a short distance at a target) I would expect not much gender difference.
