Swimming is an excellent way to reduce the risk of disease. It works your entire body and activates all the major muscle groups; contributes to muscle strength, flexibility, posture, and endurance; promotes weight loss and stress reduction; and improves cardiovascular conditioning by lowering your resting heart and respiratory rates and making blood flow to the heart and lungs more efficient. Swimming is also very low risk for injury because it places stress on your bones, joints, and connective tissues, thanks to the buoyancy of the water. Swimming 15 to 30 minutes each day can have a very positive effect on your overall health.
The Los Angeles Times is reporting on how the Marine Corps has hired 27 certified athletic trainers—most with experience tending professional and college athletes—to oversee training for enlisted recruits and officer candidates at sites throughout the United States. According to the article, this is a new direction for the Corps: Not that long ago, the drill instructors might have dismissed recruits who complained of being injured and ordered them back into action.

Many who suffer from a lot of stress also have high blood pressure and do not exercise. People who practice some form of activity or exercise benefit from less stress associated with personal, family, and work situations. Reducing stress will improve your health. Exercise helps improve your stress tolerance and also can strengthen your cardiovascular system, increase endorphin levels, and keep you mentally focused. Bike rides, power walking, and yoga are some of the many inexpensive, time-efficient ways to improve your general fitness and reduce stress. The Mayo Clinic has more good advice on how and why to reduce stress.
Continuing to work out is important because you do not want to lose the strength and endurance you have built up. Reversibility occurs when training stops or decreases. To ensure that you don’t lose your progress, you must “use it,” or else you will “lose it."
In any training program, you should follow a day of hard, intense exercise with one or even two days of “easy” training. This gives the body and mind time to recover before the next “hard” day. In addition, this helps prevent overtraining and encourages variation in your workouts.
There’s probably no other body region people work on so hard to get results than the abs. The common goal of sporting a “six-pack” is why abdominal equipment machines make up the largest part of the commercial fitness industry. People are constantly searching for the key to the washboard stomach they desire, whether it’s the newest fad piece of equipment or traditional bodyweight-driven exercises.
Unfortunately, many of these abdominal exercises provide little improvement to the target musculature and inadvertently place the lumbar spine in a position that could lead to lower back pain and injury. Just a few examples of hip-flexor-dominant exercises that can place the exerciser at risk are supine leg lifts, supine leg lifts with partner-assisted push down (a partner pushes down on the raised legs while the exerciser attempts to decelerate leg movement), hanging leg lifts, leg levers (lying supine while maintaining feet six inches off floor), and leg levers with unilateral or “scissor” kicks are.
To understand why these movements are both inefficient and contraindicated, it’s important to have a basic understanding of the abdominal anatomy. The rectus abdominis, the primary “six-pack” muscle responsible for the flexion that occurs during a curl-up, extends from the pelvis to the lower sternum. It is not involved in moving the legs. The hip flexors are responsible for the leg movements in the exercises mentioned above, while the rectus abdominis and associated muscles attempt to stabilize the spine Without adequate stabilization, the strong pull of the hip flexors leads to a marked anterior tilt of the pelvis. The abs are often unable to maintain stability, and the strong pull of the hip flexors causes the pelvis to tilt, creating an increased curvature in the lower back that compresses the lumbar area. Over time, this can lead to back pain and injury.
As a general rule of thumb, if you’re unable to maintain a stable spine position, or if you have a history of lower back pain or injury, these exercises should not be performed. There are other abdominal exercises that you can use to train more efficiently and more safely.
Even the most novice exerciser will be familiar with this common abdominal exercise: the bent-knee abdominal curl-up, or “crunch.” It has replaced the traditional sit-up as a staple in abdominal training due to its ability to recruit the abs without excessive hip-flexor activity. By varying hand placement—across the chest, behind the head, or extended overhead—the difficulty of the movement can be increased.
Crunches with a stability ball
A popular method to increase the difficulty of crunches is to perform them with a stability ball. Therapists have used stability ball training for years, and they are now becoming a common sight in gyms, as well. By reducing stability, the ball forces the exerciser to use his or her core-stabilizing muscles to maintain position, increasing the challenge to the abs. The result is a significantly greater amount of abdominal activity when compared with regular crunches.
A method of ab training not used often is the standing crunch, in which you flex and rotate your torso in various ways from a standing position. During the high to low “wood-chop,” for example, the rectus abdominis and oblique muscles are active during both the downward and upward phases. With rotation, emphasis is concentrated on the obliques. These exercises also have more “real-world” functional relevance, as they mimic everyday movements. In addition, various types of resistance—such as medicine balls, cables, resistance bands, and cords—can be used to make these exercises more difficult.
It’s important to be aware that many common abdominal exercises are not only ineffective but, more important, can place stress on the lower back. Try one of the safer alternatives above, focusing on correct form. The right abdominal training can benefit your trunk muscle strength and endurance, increase core stability, and improve functional movement—and can also start you on your way towards developing your “six-pack” abs.
Carrying extra weight in the form of fat has many downsides: It not only impairs your self-image, but it also hinders your athletic performance, leads to disease, and contributes to the aging process. What’s the best way to lose that extra flab? While intense resistance and endurance training—such as lifting weights and running—will achieve great results, experts say that the best form of fat loss is fat prevention. Here are a few tips to help you maintain a healthy lifestyle and avoid fat accumulations:
- Find activities you enjoy, like swimming or running with a friend.
- Participate in community events that encourage exercise.
- Get outdoors with your children and pets.
Remember that it’s important to begin slowly and increase exercise gradually so that physical activity is an enjoyable experience. You can get more tips from this news release by the American College of Sports Medicine.
With the schedules of most Americans more hectic than ever, many individuals find it difficult to fit in a long run outside or make the trip to a gym. Here are some simple ways to change your lifestyle and get some exercise: If you live near a place you go to regularly, such as the grocery store or a friend’s home, try walking instead of driving. According to the American Hearth Association, for every hour you walk, you could add up to two hours to your life! If you have children who like to play, whether at the park or at home, play with them. It will keep your children healthy, too. Instead of sitting down to watch your favorite TV show, invest in a few pairs of dumbbells or resistance bands and work out while watching that show. If your house has stairs, there are all kinds of exercises you can do on them.
Every small thing you do adds up, so whether you try bicep curls with groceries or climbing on the monkey bars with your kids, you’re doing something to help keep your body healthy. For lots more about how to fit fitness into your life, check out Get Moving! from the American Heart Association.
One review of studies on the effects of plyometric (explosive jump) training, or PT, suggested that plyometric training can enhance vertical jump ability and leg power for healthy individuals. This training can be as simple as drop jumps, counter-movement jumps, alternate leg bounding, and hopping. And there are PT exercises for the upper body, too! The purpose of PT is to improve your athletic performance by increasing the speed or force of muscle contraction that enables you to jump higher, run faster, throw farther, or hit harder during a game. The full article is available online from the British Journal of Sports Medicine.
The last excuse a trainer wants to hear from a client is that they don’t have enough space—or the right space—to exercise. The truth is that with a little effort and imagination, you can find a whole world of places and practices to improve your strength and endurance. Just think about all the free equipment outside at the park, on your way to work, or at your child’s school playground. You can make use of just about anything. Want to gain upper body strength? Start climbing the monkey bars and don’t stop ‘til you drop. Or try push-ups—a great way to get moving without standing in line at the gym. All you need for walking or running is a good pair of shoes and any path, road, or bike trail—the same places work for a bicycle, too, and they don’t cost a dime. By now you should be getting the picture. Just get rid of that mental block about needing a special place or equipment that is keeping you from getting a healthy, fit body. Just think of all the new forms of exercise waiting for you the minute you walk out the door! Here are five simple exercises to get you started.
