It is thought that exercising early in the morning will provide better energy throughout the day.To test this idea, subjects are recruited and randomly assigned to two groups.For 30 days, members of the experimental group will walk from 7:00 to 7:30 AM, Monday through Friday.Members of the control group will do no walking.At the conclusion of the study, each subject will answer the 10 questions on the Acme End-of-the-Day Energy Scale. The instrument produces a score between 1 and 100 (1= extremely low energy, 100 = extremely high energy).
