You have to factor in so many things as you prepare to address a crowd. Of all the things you will do, you cannot afford to forget to keep the crowd excited. If you were to receive proper public speaking training, this would not be a problem.
Body language matters a lot when it comes to how you will excite the crowd. The body has to radiate energy for the audience to pick up on it and stay excited too. There is a lot you communicate through non-verbal cues. This kind of communication reaches further than any words you could use.
The first thing to do would be to establish authority over your space. If you allow yourself to become nervous, you shall soon find that even speaking is hard. Your body language shall communicate defeat, leaving your message in shreds. You can beat that moment by simply assessing your physical presence. You can check whether your spine is aligned the right way. By taking the front and center position, you shall begin to feel more in charge. Do not allow there to be a barrier between you and the audience. When you are directly linked to the audience, they will take in your message much better.
You should also not remain rooted there. As much as the space may be limited, some movement is necessary. This does not mean you keep shifting with no reason. There is a need to keep your movements with purpose. Avoid extended periods of stillness. Moving to another section should be to connect with more people better. Each time you stop, you need to make a point before moving. There is also a need to avoid repeating a movement too much. This only betrays your nervousness, and how you are trying to overcome it.
You may also have to incorporate hand gestures. Hand gestures are what people look at when they wish to decide whether to trust you or not. The impression you create on someone determines whether they will take your message seriously or not. If they do not trust you, your message will not go far with them. The support your body language gives your message determines whether they too will find the message appealing. Those who keep their hands hidden find that their message does not go far. If you keep your hands close to each other in front of your torso, you appear more trustworthy, and so does your message. Using more gestures is a sign of excitement over what you are saying. You need to avoid going overboard with them.
You have so much to learn about body language, like eye contact and how to use it. You have to contract a public speaker coach for those lessons. Moxie san diego shall help you learn about public speaking.
