When is the best time to exercise during the day?

When you can: No best time - depends on when you have time. Just make it part of your schedule. Don't let other things interfere - as important as healthy diet, proper sleep, interacting with family and friends - it's a balance of life.

It depends: Research shows that people who exercise in the morning are more likely to actually get it done. As the day goes on , more things compete for urgency with exercise. The "best" time to exercise for stress relief and sleep, however, is after work.
