A comment (or complaint) I hear often is the lack of time to exercise due to work or missing class due to late nights at the office. Sometimes our long days and nights at the office can lead to more than missed workouts.
Stretching throughout the day sounds like one more task you don't have time for, but the benefits outweigh the headaches, stress, pain, and possibly injury.
Below are some good illustrations with stretches and exercises that you can do in the office or workplace. Plus- you can do them anywhere. On the clock or not.
Another place to find good info is darebee.com. They have a whole library of "no-equipment illustrated easy-to-follow routines specifically designed for workplace conditions." You can download the workouts at darebee.com/100-office-workouts.html
Of course, you should consult your physician or other health care professional before starting this or any other fitness program to determine if it is right for your needs.
