The Boxing Stance

http://www.self-defender.net/boxing-techniques.htm

While I was rereading my old posts today, I realized that I kept referring to the "stance," but never actually explained what that meant! So today, I will explain to you the perfect boxing stance, a position that will allow you to just as easily move to strike as to block. In order to do so, your stance needs mobility, balance, flexibility, and stability.

You should think of the placement of your feet as though there is a between them. Your front foot (the opposite of your stronger hand) should hit the line on the left side. Your other foot should be shoulder-width apart from the front foot, and that heel should hit the right side of the one-inch imaginary line. Both feet should not be facing the target, but rather at an angle, your back foot a little more facing the right.

What Not to Do:
1) Face forward... This position leaves more of your body open to attack, and you will not have as much room to really throw your body behind a punch. Also, your balance will not be nearly as good.
2) Too square (front foot is farther left, away from the line, and feet are pointing towards the same direction)... Same problems as #1. 
3) Too straight (back foot is farther left, on the line)... The right hand is too far to make a quick strike and to defend, and you are easily thrown off balance.
4) Feet are too wide apart... This stance has poor mobility and balance.

Things to Remember:
-You should always be on the ball of your back foot.
-Your knees should always be bent.
-Relax your hips, shoulders and arms for mobility.
-Keep your weight balanced between both feet.
-Keep your elbows close to your body.
-Hands should protect your face, and your chin should be down.
-Don't turn your shoulders completely towards your opponent, just slightly.
-Left hand is at nose level; right hand is at cheek level.
