It really depends upon the type of exercise you are normally undertake. Regular gym work such as running, cycling or light exercise classes may be gently recommenced at two weeks following surgery. You should work up to normal activities in terms of intensity by one month. You may wish to delay this process slightly for more intense workouts or for heavy weightlifting. Contact sports such as boxing or martial arts are generally discouraged following this type of surgery as further injury to the nose is possible.
