Headline vs Study

• Headline: The Best Time of Day to Exercise.
• Study: "The study was not designed to investigate the effect of the timing of exercise and the reason for subjects performing exercise in the morning or evening was depending on the scheduling possibilities and personal preferences."
• Critique: When Is the Best Time for Exercise?
