The American College of Sports Medicine and the American Heart Association recommend doing moderate-intensity cardiovascular exercise for 30 minutes a day, five days a week (for details of these guidelines, click here). However, elite athletes and tactical Warfighters need to train more to achieve higher levels of fitness—see the Navy Seal Fitness Guide and the Building the Soldier Athlete Manual for more information.
Monitor your heart rate to ensure that you are training in the appropriate range for your performance needs. This simple practice will help you track the way your body responds to training to effectively optimize your physical performance. The American Council on Exercise (ACE) has information on how to monitor your exercise intensity using your heart rate, as well as an online tool for calculating your target heart rate. A similar online calculator is available from the Army’s Hooah 4 Health website.
Fitness is so important to your mental and physical health. Consider scheduling exercise into your work day; put it on your calendar! Keep packable tools like elastic tubing and bands at your desk. You can easily strengthen your chest, upper back, shoulders, arms, and legs in just a few minutes, two or three times a week. All without leaving your office!

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.

Try these tips from the National Institute of Arthritis and Musculoskeletal and Skin Disease to prevent knee injury while you exercise:
- Avoid bending your knees past 90 degree when doing half knee bends or squats.
- Avoid twisting your knees by keeping your feet as flat as possible during stretching.
- When jumping, land with your knees bent.

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.

Science Daily reports on a new study published in the Journal of Applied Physiology which indicates that training in warm weather not only improves heat acclimation and performance in the heat, but also improves performance in cool conditions. Click here for more details about the study.
