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.
Since injuries can occur in physically active individuals, here are a few tips to help you stay injury free:
- Warm-up and cool-down after exercise;
- Use proper form;
- Spread activity throughout the week, not just the weekend;
- Wear appropriate safety gear;
- Increase intensity and time gradually, and
- Cross train to prevent overuse injuries.

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.
An article published in ScienceDaily reports on a study which shows that regular exercisers are less likely to fall sick with a cold or flu. The study participants who exercised more were less likely to report a cold or flu in the fall and winter seasons, and if they did get sick, they had fewer symptoms with shorter duration.

Jumping rope is a good way to maintain fitness, particularly in confined environments such as on board a ship. If the pace is fast, the energy expenditure is similar to running. The Navy Seals Fitness Guide suggests the following ways to add variety into your jump rope routine:
- Boxer’s Dance: Shift weight from right to left with both feet together.
- Run: Jump to the right while lifting the right knee, then switch to left side.
- Jumping Jack: Jump 2 times with feet together then on the third time, do a jumping jack.
- Knee-toe: Tap right toe on the floor, jump to your left foot while lifting left knee up high, then switch.
Your feet are so important – they work hard to get you from place to place! You walk, jog, run, cycle, and swim with your feet, so take good care of them. Easy tips include wearing comfortable shoes that fit properly, shopping in the daytime for shoes when your feet are more swollen than in the morning, walking to exercise your feet, wearing well-fitting stocking and pantyhose, and seeing a podiatrist to deal with corns or calluses.
