I start with this question whenever I give a talk about exercise and mental health. Like the trial attorney who asks only questions she already knows the answers to, I pose the query with certainty about the outcome. Research backs the near-universal observation that you almost always finish a workout in a better mood. Exercise leads to both types of good moods psychologists talk about: positive high activation (feeling alert, excited, happy) and positive low activation (feeling calm, content, relaxed).
So if you want to lift your spirits with exercise, the most important thing about your workout is that it exists. Anything is better than nothing. That said, how you structure your workout - how long, how hard, etc. - can supercharge the post-exercise mood boost.
Understanding how to construct a mood-lifting workout starts with understanding why exercise leads to feeling better mentally.
You've probably heard of endorphins, which are among the body's natural opioids and circulate in greater numbers during exercise. The exercising brain enjoys higher levels of endorphins as well as endocannabinoids (which act on the same receptors as the psychoactive ingredient in marijuana), neurotransmitters and other feel-good chemicals.
Another contributor to a calmer mood is the slight increase in core temperature that occurs during exercise, which reduces muscle tension. "After exercise, the nervous system is quieter, your muscles are more relaxed, and that feeds information into your brain that you interpret as a good feeling," says Carson Smith, a kinesiology professor at the University of Maryland.
Your mood, however, is determined by more than what's going on inside your body. Exercise is a regular opportunity to hone your self-efficacy, which is the belief that you can accomplish goals you set for yourself. Pushing through a workout makes you feel better about yourself and reinforces the knowledge that you can be successful in challenging situations. For some people, the harder the workout, the better their mood after. "The pleasure of that achievement overshadows any sense of displeasure that existed during the actual exercise," says Panteleimon Ekkekakis, a professor of exercise psychology at Iowa State University.
With that background, here's what research and experience suggest about workout variables.
Any form of purposeful exercise trumps incidental physical activity, according to a Heidelberg University study that asked subjects to record their moods after both working out and engaging in "nonexercise activity" such as climbing stairs or cleaning. Only the workouts boosted mood; in fact, the daily-life activities decreased feelings of calmness. So, make the effort to do some form of exercise. A short walk, a brief session of stretching or yoga, or a handful of body-weight exercises (planks, pushups, dips, etc.) all count.
Longer can be better, assuming you have the endurance and don't get tighter or more sore as you keep exercising. Endorphin levels, for example, start to surge after about an hour of moderate aerobic exercise, and increase exponentially after. In part because of higher endorphin levels, many people find that longer workouts tend to produce the pleasant calm of the positive low activation mood mentioned earlier.
Keep in mind, though, that psychology plays an important role. A University of Wisconsin study found that people were in a better mood when they picked their own intensity level instead of a prescribed moderate-effort workout, even though their endocannabinoid levels were higher after the latter. David Raichlen, the anthropology professor behind the University of Arizona research, says, "My biggest mood boosts are after tempo runs or intervals," which are much more intense than a moderate-pace outing.

Type
Aerobic exercise tends to trigger more release of the feel-good brain chemicals than anaerobic workouts, such as weightlifting. But the best type of workout is one that you do. If you love spin class, go to it. If running is your thing, hit the road. If weightlifting is most appealing today and swimming calls tomorrow, heed those hints. Doing exercise you enjoy is the key to consistency.Any form of purposeful exercise trumps incidental physical activity, according to a Heidelberg University study that asked subjects to record their moods after both working out and engaging in "nonexercise activity" such as climbing stairs or cleaning.

A short walk, a brief session of stretching or yoga, or a handful of body-weight exercises (planks, pushups, dips, etc.) all count.
Duration
Even a 10-minute walk around the block increases blood flow and gives you the chance to mentally regroup and improve your mood. A significant mood boost requires at least 20 minutes of exercise, according to most research.Longer can be better, assuming you have the endurance and don't get tighter or more sore as you keep exercising. Endorphin levels, for example, start to surge after about an hour of moderate aerobic exercise, and increase exponentially after. In part because of higher endorphin levels, many people find that longer workouts tend to produce the pleasant calm of the positive low activation mood mentioned earlier.
Intensity
In terms of better brain chemistry, easy- to moderate-intensity workouts are best. (If you train by heart rate, this effort level occurs between 60 percent and 80 percent of your maximal heart rate.) For example, a University of Arizona study found the biggest boost in endocannabinoid levels when people ran at an easy or moderate pace for 30 minutes. When the people walked or ran very hard for 30 minutes, their endocannabinoid levels decreased. (The subjects were fit runners, so for them walking slowly was a much lighter intensity than their usual workout.)Original Source
