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.
Calluses and corns often are not painful, but they can cause pain when you are walking or wearing shoes. And they may make it hard for your feet to fit in your shoes. Any type of pressure applied to the callus or corn, such as squeezing it, can also cause pain.
