The document discusses using brain science to make training more effective through incorporating movement and engagement. It recommends adding "body breaks" every 10-20 minutes where learners stand, stretch, walk around, or discuss the material to boost learning and memory. These brief breaks boost oxygen to the brain and prevent restlessness that can occur around the 10 minute mark. The document provides examples of different types of body breaks trainers can use, including having learners stand and discuss key points, write summaries, or talk through the material with peers. Regular body breaks help train the brain through movement and engagement.
