[That Foreign Guy]

Good post.

Back in my younger days I used to get into "disagreements" with people at the bar quite a lot (macho students think they can prove their toughness by taking on soldiers). You can tell if a guy is serious by watching his torso - if a shoulder moves backwards he's throwing a punch with the other arm.

But yeah, try throwing a punch in the mirror without the opposite shoulder going backwards. Unless you're in almost a completely side on stance, it's almost impossible (and even harder to throw a good one).

The surest way to throw like the proverbial girl is to not involve the kinetic chain properly. As anyone who has tried to learn how to throw with their off hand will know - there's a lot of stuff that goes on in a throw before whipping the arm through.
