The player who tries to dribble must be sure that it is he who must always take the initiative. Sometimes the opponent will offer you a way out - watch out for this as it might be his way of taking the ball from you. To be good at dribbling you need to have a lot of confidence in yourself, a great deal of practice and a good sense of balance. Keeping your balance will become easier if you are able to understand the basic laws of equilibrium. I'll try to explain to you very simply what I have learned.
Every solid body has a center of gravity.
In the human body it is situated in the middle of your torso at about your navel. Whenever an imaginary line from the center of gravity falls in the middle of the support area it is said that the body is in equilibrium. In the human body the support area is the space between the two feet. If your feet are together your equilibrium will be less because the center of gravity can 'fall' outside the area made by your feet. If you stand with your feet apart the support area will be larger.
