If you can answer that, you are well on your way. Since most groups of adults have a variety of learning styles, the training information needs to be presented in a variety of ways. Use written words, visuals, audio, live action, practice, etc. There needs to be a mixture within every session. If that were not the case, if everyone learned the same way, we could just give everyone a book and be done with it.
All adults compare new information with their previous knowledge and experience.
As a trainer you need to give learners the chance to reflect, question, and compare. A smart trainer builds this step into the program, because the learners are going to do it anyway. It makes common sense that a trainer will allow the learners to discuss these thoughts in an open and supportive way. All learners have their own unique perspective, experience, and learning style, and that will affect how they finally understand the training. After training is over, the learners will go back to work and try to decide if the information they received in training is worthwhile or just a pile of compost.
