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 common conditions of areas of thickened skin often seen on the bottom of the foot or toes. They may cause you pain or discomfort. Or, they may simply be unattractive, especially large calluses that develop on the heel.
