When should I exercise? Morning, noon or night?

There's no actual better time to exercise, you can exercise at anytime of the day that you prefer. Exercising in the morning can be a great way of starting the day as you get the heart pumping and blood circulating through your body after having spent a few hours asleep with no activity. And it also gets exercising of your to-do list for the day. It takes away the chance for you to "put it off for later". Exercising in the afternoon could be very hot and you have to make sure you're even more properly hydrated because of the heat. My favorite time to exercise is at night as it's not so hot. But anytime of the day is a great time to exercise.
