What's the best time of day to stretch?

It is seen that people who work out in the morning tend to maintain more regularity that those who prefer to exercise in the evening. But with the busy and unpredictable schedules that most people have, finding a regular routine is tough. So i would say regular exercise is what matters. Finding the right time in our schedule should be the priority. If done regularly, morning, evening or even a night time workout will show results.
