There are a few factors to consider when training/learning how to hit a volleyball, also known as an attack or spike. One of those factors is the approach, the “run” towards the ball after it is released from the setter’s hands. First, make sure you are standing behind the ten-foot line with your right foot slightly in front of your left foot and arms down beside you. Next, take a step with your left foot and then another with your right foot. You will then want to plant or hop quickly with your left foot. You can think of it as well as left- right, left. You will want to practice this by starting out slowly and as you get the hang of it, speed it up to a quick “run”. Bend your knees and jump bringing your arms up in the air.
The next factor to consider when hitting a ball is your positioning. Having the correct positioning will make a huge impact on the way you make contact with the ball and hit the ball. The most important detail to having proper positioning is, always, always; keep the ball in front of you. By doing this, you will be able to place the ball where you’d like. This is once you have gained some experience.
Your arm swing also plays a big role in being able to properly hit the ball. One rule of thumb to keep in mind is to always put your entire body behind the hit/attack, not just your arm. Keep your arm straight in the air and open your hand. Make sure you strike the ball on top and in a downward motion.
Timing is the most difficult part of hitting. The best advice I can offer to you in order for you to master your timing is to practice, practice, and practice as timing is dependent on many variables coming together such as the height of your vertical jump and the speed of your approach.
