Can’t find time to fit exercise in during your day? Then get fit at work! Consider biking or walking to work, if practical. If not, walk around your workplace before or after work, or during work breaks, for 20-30 minutes. Lunchtime walks with a friend are fun and a stress reliever. Use the stairs rather than elevator.

It's true that exercise can help prevent the common cold by strengthening your immune system, but you should be cautious if you are considering an intense workout when you do fall sick. Some recommendations from the American College of Sports Medicine (ACSM) are to:
- Exercise moderately when the cold symptoms are confined to your head,
- Stay in bed if illness spreads beyond your head - don’t “sweat out” your illness, and
- Resume your exercise program slowly as you recover.
Check out ACSM’s guide, Clearing the Air on Exercise and the Common Cold for more information.

According to the American Council on Exercise (ACE), your sneakers are ready to be replaced after three to six months of regular use, or approximately 350 to 500 miles of running. Looking at the wear patterns can provide good indicators that your sneakers need to be replaced.
When the time comes to replace your sneakers, ACE has to help you find the perfect, and affordable, pair. They suggest that you buy sport specific shoes, test for stability, try on shoes at the end of the day when feet are their largest, and allow room for socks. Although some sports scientists will advise you to consider your foot type when purchasing sneakers, there is conflicting scientific evidence on this recommendation.
