- 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.

Have you ever been tempted to try the exercise equipment advertised on late-night infomercials—the products that promise to enhance various body parts or provide a great workout for a low, low price? Most of it isn’t necessary to get into the shape you want. Some of the most effective workouts can be done at home—with only your own body weight. It’s not that equipment is bad—correct use of weights and some machines can be very effective—but it isn’t necessary, nor is it an excuse to prevent you from getting in a good workout when equipment isn’t available.
There are some clear benefits to exercising at home without the use of equipment, including saving time and money that you would spend at a gym. Most importantly, exercising by using your body weight provides you with the ability to exercise anytime and anywhere—you aren’t restricted only to the times when you have access to the piece of equipment or device. Also, there are a variety of ways to go about a home-based program, ranging from workouts on DVD to a workout you create for yourself. Those already familiar with online workouts may know that YouTube has been afire with videos of extraordinarily fit people demonstrating their workouts done with minimal equipment in their homes, backyards, or local parks. Always proceed with caution—these videos are impressive and can be useful, but realize that they come with a risk of serious injury. Before you begin any home workout, consult your physician and/or an exercise professional to determine what is safe, and best for you.
We list some examples below of fitness moves that can be performed at home without equipment. These moves should be performed properly and at the right intensity level for them to be effective and safe. The American Council on Exercise (ACE) provides an Exercise Library that displays the proper form for many exercises.

ABC News affiliate WSET.com (Lynchburg, VA) has an article on rhabdomyolysis and exercise - specifically working out with P90X, an high-intensity exercise program. Rhabdomyolysis is the breakdown of muscle fibers resulting in the release of muscle fiber contents (myoglobin) into the bloodstream. Some of these are harmful to the kidney and frequently result in kidney damage.
Rhabdomyolysis is a potentially deadly condition that can be triggered by overdoing exercise/workout programs.
