1. If you're angry that your neighbor had the nerve to complain about your messy lawn, try kickboxing or a game of tennis. The physical act of hitting something will help you release energy and hostility.
2. If you're worried about your child starting a new school and can't stop ruminating over every little thing that might happen, try yoga or ballet. The slow, meditative movements help calm your mind.
3. If you feel powerless after losing your job, try strength or resistance training. Studies show that as you increase your physical strength, your confidence gets a lift as well.
