In one sentence, describe what the following article is about: . Blocking is very easy. Blockers should be cocked and ready to jump up. Generally, you should be half an arms length away, off from the net. Watch the ball and then jump. When you are in the air, do following steps. Swing your arms up to get height. Hold your arms straight, hands stiff. When the ball comes over, just touch the ball, keeping hands stiff, with your palms. Even if you aren't as tall as the net, just getting a glimpse of an emerging body will scare them and throw the opposing team off. Do this every play, even for just a bump. Keep your hands up at your shoulders. After you jump, penetrate the net with your hands and hold stiff against ball. If your fingers are not stiff, you can risk hyper-extension injury and the ball will go past your fingers.
Summary: Position Hands and arms. Do this move.

In one sentence, describe what the following article is about: Most often, you'll hold the call by the sound chamber, wrapping your fingers around the hole to mute it as you would a harmonica. Conversely, you can hold the call like a cigar between two fingers and mute the end with the palm of your other hand. To find your diaphragm, cough into your hand. The muscle you use when you cough is the best way of forcing air into the duck call and making the most accurate sound. You don't even have to have your mouth open to force the air this way, so practice with your mouth closed. Think of it less like you're blowing a bubble and more like you're trying to get something out of your lungs. Duck calls are short, repetitive, sharp bursts of sound, not long drones. Practice cutting the air off with your throat, making an oof sound. When you're pushing air with your diaphragm, open your lips slightly and put the call up to them. It's a good way to trick yourself into doing it perfectly. If you can make a full "quaCK" sound, cutting off the air in an accurate sounding approximation of a duck's quack, you've got the right technique down. Much more difficult than calling with a good duck call, the hand technique is worthwhile to know in situations where your call might be broken or forgotten in the back of the truck. It's also a great way to score points with old-timers. To do a hand-call, curl your thumb into your palm and close your fist around it. Next, dip your clenched fist in water to trap some water in the crevice your palm makes. This helps to put an accurate sounding "rattle" in your call. Blow between your thumb and palm, changing the shape by flexing your thumb slightly. This will take lots of practice to get right, but then you'll always be able to call ducks with or without a call.
Summary: Hold the call properly. Blow from your diaphragm. Control the air with your throat and your mouth. Put the call between your teeth. Try learning old-time hand-calling technique.
