Dick Eastman is the International President of Every Home for Christ, headquartered in Colorado Springs, Colorado. With his book, The Hour that Changes the World, he has developed a practical way for ministers and laypeople to pray for an hour a day with amazing results. Dick Eastman suggests that one divides an hour into 12 periods of 5 minutes. After 5 minutes you change to another form of prayer. This is a great tool to help a person who has never prayed for 1 hour.
This pdf link gives a simple guide on how to pray each of the five minutes.
