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.
You might have a callus on the bottom of your foot if you see any thick or rough areas of skin, if you have a hardened or raised bump or if you feel any tenderness or pain beneath your skin, according to the Mayo Clinic website. Callused skin also can be dry, flaky or waxy.
