For many people, exercise is a main method of reducing stress and promoting relaxation. One of the benefits of regular aerobic exercise is its moderating effect on emotions, both long-term and short-term. If you feel angry or upset, a brisk walk or run or a half hour of lifting weights will often put you back in a good mood. While exercise is a great way to burn up excess energy and dissipate tension, it does not necessarily teach you how to process stress, and is best used as a complement to another technique such as breathing, visualization or meditation. mediation is an excellent promoter of relaxation as well as a good form of non-aerobic body conditioning. It perfectly complements aerobic exercise.
