Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Physical Exercise shopping experience:

1. Compare - without doubt the biggest advantage that the Physical Exercise offers shoppers today is the ability to compare thousands of Physical Exercise at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Physical Exercise? Wrong! If the Physical Exercise is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Physical Exercise then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Physical Exercise? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Physical Exercise and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Physical Exercise wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Physical Exercise then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Physical Exercise site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Physical Exercise, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Physical Exercise, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Physical exercise is manual activity that develops or maintains physical fitness and overall health. It is often practiced to strengthen muscles and the cardiovascular system, and to hone sport skills. Frequent and regular physical exercise boosts the immune system, and helps prevent diseases of affluence such as heart disease, cardiovascular disease, Type 2 diabetes and obesity.Stampfer, M., Hu, F., Manson, J., Rimm, E., Willett, W. (2000) Primary prevention of coronary heart disease in women through diet and lifestyle. The New England Journal of Medicine, 343(1), 16-23. Retrieved October 5, 2006, from ProQuest database.Hu., F., Manson, J., Stampfer, M., Graham, C., et al. (2001). Diet, lifestyle, and the risk of type 2 diabetes mellitus in women. The New England Journal of Medicine, 345(11), 790-797. Retrieved October 5, 2006, from ProQuest database. It is also improves mental health and helps prevent depression.

Types of exercise Exercises are generally grouped into three types depending on the overall effect they have on the human body:



Exercise benefits Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a healthy weight; building and maintaining healthy bone density, muscle strength, and joint mobility; promoting physiological well-being; reducing surgical risks; and strengthening the immune system.

Frequent and regular aerobic exercise has been shown to help prevent or treat serious and life-threatening chronic conditions such as high blood pressure, obesity, heart disease, Type 2 diabetes, insomnia, and clinical depression. Strength training appears to have continuous energy-burning effects that persist for about 24 hours after the training, though they do not offer the same cardiovascular benefits of aerobic exercises. Exercise can also increase energy and raise one's threshold for Pain and nociception.

There is conflicting evidence as to whether vigorous exercise (more than 70% of VO2 max) is more or less beneficial than moderate exercise (40 to 70% of VO2 max). Some studies have shown that vigorous exercise executed by healthy individuals can effectively increase opioid peptides (aka endorphins, a naturally occurring opiate that in conjunction with other neurotransmitters is responsible for exercise induced Euphoria (emotion) and has been shown to be addictive), positively influence hormone production (i.e., increase testosterone and growth hormone).Hanc, J. 1987. Your Health Behind the Runner\'s Euphoria. \'\'Newsday, April 21, 1987,\'\' 11. Retrieved October 5, 2006, from ProQuest database benefits that are not as fully realized with moderate exercise.

Exercise has been shown to improve cognitive functioning via improvement of hippocampus-dependent spatial learning, and enhancement of synaptic plasticity and neurogenesis. In addition, physical activity has been shown to be neuroprotective in many neurodegenerative and neuromuscular diseases. For instance, it reduces the risk of developing dementia. West Virginia Department of Health and Human Resources Physical activity is thought to have other beneficial effects related to cognition as it increases levels of nerve growth factors, which support the survival and growth of a number of neuronal cells. {{cite news| first = Gina | last = Kolata | title = Why Some People Won't Be Fit Despite Exercise | url = http://query.nytimes.com/gst/fullpage.html?res=9406EEDE113CF931A25751C0A9649C8B63&sec=health | publisher = The New York Times | date = February 12, [ | accessdate = July 17, 2007 --> Similarly, only a minority of people will show significant muscle growth after prolonged weight training, while a larger fraction experience improvements in strength.

Common myths Many myths have arisen surrounding exercise, some of which have a basis in reality, and some which are completely false. Myths include:



Targeted fat reduction Spot reduction is a myth that exercise and training a particular body part will preferentially shed the fat on that part; for example, that doing Sit-up (exercise) is the most direct way to reduce subcutaneous belly fat. This is false: one cannot reduce fat from one area of the body to the exclusion of others. Most of the energy derived from fat gets to the muscle through the bloodstream and reduces stored fat in the entire body, from the last place where fat was deposited. Sit-ups may improve the size and shape of abdominal muscles but will not specifically target belly fat for loss. Such exercise might help reduce overall body fat and shrink the size of fat cells. There is a very slight increase in the fat burnt at the area being exercised (e.g Abs) compared with the rest of the body, due to the extra blood flow at this area.

Muscle and fat tissue Some people incorrectly believe that muscle tissue will turn into fat tissue once a person stops exercising; this is not literally true -- fat tissue and muscle tissue are fundamentally different -- but the common expression "muscle will turn to fat" is truthful in the sense that catabolism of muscle fibers for energy can result in excess glucose being stored as fat.Austin, B. 2006. Don't Let Your Body Go Into Starvation Mode. Wisconsin State Journal, April 1, 2006, 46. Retrieved October 5, 2006, from ProQuest database. Moreover, the composition of a body part can change toward less muscle and more fat, so that a cross-section of the upper-arm for example, will have a greater area corresponding to fat and a smaller area corresponding to muscle. This is not muscle "turning to fat" however, it is simply a combination of muscle atrophy and increased fat storage in different tissues of the same body part. Another element of increased fatty deposits is that of diet, as most trainees will not significantly reduce their diet in order to compensate for the lack of exercise/activity.

Excessive exercise Exercise is a Stress (medicine) and the stresses of exercise have a Catabolism effect on the body - contractile proteins within muscles are consumed for energy, carbohydrates and fats are similarly consumed and connective tissues are stressed and can form micro-tears. However, given adequate nutrition and sufficient rest to avoid overtraining, the body's reaction to this stimulus is to adapt and replete tissues at a higher level than what existed before exercising. The results are all the training effects of regularly exercise - increased muscular strength, endurance, bone density and connective tissue toughness.

Too much exercise can be harmful. The body part exercised needs at least a day of rest, which is why some health experts say one should exercise every other day or 3 times a week. Without proper rest, the chance of stroke or other Circulatory system problems increases,Alexander, C. 1998. Cutting weight, losing life. News & Observer, February 8, 1998, A.1. Retrieved October 5, 2006, from ProQuest database. and muscle tissue may develop slowly.

Inappropriate exercise can do more harm than good, with the definition of "inappropriate" varying according to the individual. For many activities, especially running, there are significant injuries that occur with poorly regimented exercise schedules. In extreme instances, over-exercising induces serious performance loss. Unaccustomed overexertion of muscles leads to rhabdomyolysis (damage to muscle) most often seen in new army recruits.Jimenez, C., Pacheco, E., Moreno, A., Carpenter, A. 1996. A Soldier's Neck and Shoulder Pain. The Physician and Sportsmedicine, 24(6), 81-82. Retrieved October 5, 2006, from ProQuest database. Another danger is overtraining in which the intensity or volume of training exceeds the body's capacity to recover between bouts. The Physicial and Sportsmedicine on Overtraining

Stopping excessive exercise suddenly can also create a change in mood. Feelings of depression and agitation can occur when withdrawal from the natural endorphins produced by exercise occurs. Exercise should be controlled by each body's inherent limitations. While one set of joints and muscles may have the tolerance to withstand multiple marathons, another body may be damaged by 20 minutes of light jogging. This must be determined by each individual.

Too much exercise can also cause a female to miss her period, a symptom known as amenorrhea.{{cite web| url = http://www.uoregon.edu/~hphy/AT/FATriad/links/amenorrhea.htm| title= Amenorrhea| accessdate = 2007-08-14| work = The Female Athlete Triad| author = Julia Berry| coauthors = Anne Bradley; Hillery Magness| publisher = University of Oregon, Department of Human Physiology-->

Nutrition and recovery Proper nutrition is at least as important to health as exercise. When exercising it becomes even more important to have good diet to ensure the body has the correct ratio of Macronutrient (nutrition) whilst providing ample micronutrients, this is to aid the body with the recovery process following strenuous exercise.Kimber, N., Heigenhauser, G., Spriet, L., and Dyck, D. 2003. Skeletal muscle fat and carbohydrate metabolism during recovery from glycogen-depleting exercise in humans. The Journal of Phsyiology, 548(Pt. 3), 919-927.

Proper rest and recovery are also as important to health as exercise, otherwise the body exists in a permanently injured state and will not improve or adapt adequately to the exercise. Hence, it is important to remember to allow adequate recovery between exercise sessions.

The above two factors can be compromised by psychological compulsions (eating disorders such as exercise bulimia, anorexia nervosa, and other bulimias), misinformation, a lack of organization, or a lack of motivation. These all lead to a decreased state of health.

Delayed onset muscle soreness can occur after any kind of exercise, particularly if the body is in an unconditioned state relative to that exercise.Mirkin, G. 2005. Exercise requires time for recovery. Washington Times, May 29, 2005, C.11. Retrieved October 5, 2006, from ProQuest database.

Exercise and brain function In the long term, exercise is beneficial to the brain by:

Categories of physical exercise

Sometimes the terms 'dynamic' and 'static' are used. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly.

Breathing Active exhalation during physical exercise helps the body to increase its maximum lung capacity, and oxygen uptake. This results in greater cardiac efficiency, since the heart has to do less work to oxygenate the muscles, and there is also increased muscular efficiency through greater blood flow. Consciously breathing deeply during aerobic exercise helps this development of the heart lung efficiency.Brant, J. 1996. Power Yoga -- A New Form of Ancient Practice Builds Strength and Endurance. Seattle Times, January 31, 1996, E.1. Retrieved October 5, 2006, from ProQuest database.
