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.
If your symptoms are mild, changing shoes may be all the treatment you need. Using a splint or pad to hold your toes straight also may help. Or try cushioning corns and calluses with felt padding. If your symptoms are severe, surgery may be needed.
