Since you have been using your muscles for most of the day, they’re already warmed up. Your body has been awake for a few hours and can get into exercising a bit easier than warming up the body during mornings. This is an important factor for someone who is not a “morning person.” By the afternoon you’re already awake and your muscles have been warming up all day. Some enjoy this type of exercising rather than trying to push a cold, hard start on their bodies. Because of this, many feel that noon exercise is actually easier on the body, and may lead to fewer injuries and other bodily complications.
