People who exercise regularly plan the timing of their workouts based on their work schedule, kids, social engagments, level of exhaustion etc. Time of day has frequently played a factor in creating an exercise regimen; people try to squeeze workouts in during lunch, before work, and after work, depending on a host of issues in their lives. Many exercisers have been hesitant to start working out too late in the evening, since it is commonly recommended to avoid exercising before bed because it may affect sleep patterns. However, a new study found that individuals who exercised in the evening reported sleeping just as well as those who did not exercise before bed. However, people who exercised in the morning repored the best sleep, so the timing of exercise may still play a factor in slumber. Everyone is different, so trial and error is important to determine what works best for you.
