Firstly, a person has much willpower when he or she starts his day. Whereas if one decides to workout at night, he or she may no longer have the stamina because of the stress and workload during the day.
Secondly, research has shown that people won’t be tempted to munch on those sweet treats after a morning exercise. It’s not true that working out will make you hungry.
Thirdly, a morning fitness regime can boost one’s mood and confidence and research from the University of Vermont shows this positive mood effect can last up to 12 hours. For this reason, there’s a good chance the sunshine you bring can influence other people.
