So remember: The bare minimum amount of activity to stay healthy and sleep well is 150/75 minutes of moderate/vigorous activity a week; double that amount if your goal is to lose weight.
To prevent corns and calluses and relieve discomfort if they develop: Do not wear shoes that are too tight or too loose. Wear well-padded shoes with open toes or a deep toe box (the part of the shoe that surrounds the toes). If necessary, have a cobbler stretch the shoes in the area where the corn or callus is located.
What is a callus? Corns and calluses are hard, thickened areas of skin that form as a consequence of rubbing, friction, or pressure on the skin. Corns and calluses form on the feet and can make walking painful. Although corns and calluses are often talked about together, they are separate conditions. Corns generally occur on the tops and sides of the toes. A hard corn is a small patch of thickened, dead skin with a small plug of skin in the centre.
