Finding the time to run can oftentimes be the biggest challenge... Research studies indicate that those who exercise early in the morning are more consistent and stick with their programs as compared to people who work out later in the day. Morning is the time when you probably are most rested both physically and mentally. The later in the day you wait to run, the likelihood that unexpected personal or professional obligations will arise, sabotaging your best-laid plans. You may also find that your motivation drops to its lowest level after a stressful or physically demanding workday.
