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.
Corns and calluses are hard, painful areas of skin that often develop on the feet in response to pressure or friction. They happen when the skin tries to protect an underlying area from injury, pressure, or rubbing. Neither is dangerous, but they can cause irritation.
