Morning exercise is one of the best things you can do for yourself. There are many reasons why you should try exercise first thing in the morning. People that practice this will probably tell you that it’s an addictive routine, and that it partially shapes their day.
And as far as the addiction goes, try asking them whether they can quit exercising in the morning. They will only ask you: “why?”
And this actually sums up a lot. You see, that’s the real question, not why to exercise in the morning, but why not?
