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.
Because a bunion occurs at a joint, where the toe bends in normal walking, your entire body weight rests on the bunion at each step. Bunions can be extremely painful. They're also vulnerable to excess pressure and friction from shoes and can lead to the development of calluses.
