Make Yourself Bigger

To play down low you have to make yourself bigger. You do this by setting yourself up with an exaggerated basketball stance.
Spread your feet wider than shoulder's width. Make sure your elbows are flared and your hands are up. What this big stance does for you is help keep your defensive man from stepping around you or reaching over your back to either steal or knock the ball away.

When fighting for position down low, the most important thing to do is to present yourself as a good target for your teammates. With so many players cutting in and out of the low-post area, this is often difficult.

Your own defender will be doing his best to get in front of you and cut off any passes, and any other defender coming through the low-post area will throw out his hand if it looks like he can steal an incoming pass.

Keep your man behind you at all times by continually maneuvering in front of him, blocking him with your upper arm, while at the same time presenting a target for a pass with your other arm held high. It's extremely important to have contact with the body of your defender so you can always know where he is and what type of move you can try to make.

To work successfully in the low post or in the lane, it will take a coordinated effort between the passer and you to finally get you the ball.
