The body is the 'real' presentation. If the introduction was well prepared and delivered, you will now be 'in control'. You will be relaxed and confident.

The body should be well structured, divided up logically, with plenty of carefully spaced visuals.

Remember these key points while delivering the body of your presentation:

do not hurry
be enthusiastic
give time on visuals
maintain eye contact
modulate your voice
look friendly
keep to your structure
use your notes
signpost throughout
remain polite when dealing with difficult questions
