Too Much Water Can Kill
Long distance runners and other endurance athletes have long been educated to believe that drinking lots of fluids during a long distance or endurance event was critical. And if you didn't drink enough water, you ran the risk of dehydration.
Researchers - studying 488 runners in the 2002 Bost Marathon found that the bigger danger is in drinking too much fluid (water or sports drinks) rather than not enough. They found that 62 of the 488 runners, more than one in eight, had a serious fluid and salt imbalance after the event. And three of them were in the danger zone.
Hyponatremia - a condition where drinking too much water or other fluids to the point where the salt level in the body drops too much - can develop during marathon races where the runners drink constantly to stave off dehydration.
Runners who actually gained weight (anywhere from 4-11 pounds) during the event and very thin runners are most at risk. Runners who drink sports drinks with very little salt in them are least at risk. The goal of drinking during a race is to replace water that is lost, not to take in more than you are losing.
A good way to learn how much is right for you is to weight yourself before a heavy training session. Then drink and record how much liquid you consume during the trainging. Then weight yourself again. If you find that you weight more after the training than before, you should cut down on your liquid intake. By performing this exercise, you will learn how much liquid you really need to injest during an event and be able to pace yourself accordingly.
Hyponatremia can begin with confusion and lethargy and can progress rapidly to more severe symptoms. They can include twitching, siezures, stupor, coma and even death.
In recent years, hyponatremia has killed several amateur marathon runners as well as competitors in the Marine Corps Marathon.

Integrated Training for Improved Cycling Performance - Part 1
As we all know cycling is a great way to improve your overall cardiovascular fitness. However, what you may not know is that over time the demands of cycling can lead to muscular imbalances which can limit the body's ability to perform at peak level and dramatically increase chance of both over-use injury and chronic pain.

Integrated Training for Improved Cycling Performance - Part 2
The previous article looked at postural issues and possible muscles imbalances involved with cycling. Now that we have an understanding of the imbalances that arise from a prolonged cycling position, we can develop an effective program for correcting those postural distortions.
Fat Burning Exercises
Fat burning exercises are the slow, aerobic, long duration types of exercise that involve most of the major muscle groups. Your body will burn a higher percentage of calories from fat with lower intensity cardio exercises.

Cardiovascular Training - From the Heart!
Cardiovascular training, or aerobics, requires a different approach than other body parts. At the "heart" of cardiovascular training is one basic premise: if you elevate your heart rate to 65-80 percent of your maximum and keep it there for a period of at least 12 minutes it will stimulate the production of fat-burning enzymes. It will also strengthen your heart and increase the capacity of your lungs to re-oxygenate your blood more efficiently. The idea here is not to work yourself to a frenzy and go beyond your target heart rate, but to stay within that magic training range of 65-80 percent of maximum for a minimum of 12 minutes and, optimally, for 20 to 30 minutes.
Stay in Shape - Cycling Workouts For the Winter Months

Spinning Classes - Indoor Stationery Bicycle
Over the years I have changed my exercise routine continuously. That wasn't exactly planned, but it probably kept my interest up. I started with twice-a-week through Adult Education at the local junior high school. That was simple non-impact bending. That was too easy. Then I moved into Jazzercise, which was high impact. I began to really enjoy that. But it was only offered twice-a-week. My energy level blossomed. I now am up to six days per week, and sometimes even that isn't enough!

Running is an ideal symmetrical activity for keeping fit. However, it is common for people to blame running for injuries rather than accept that it may be how they run that is at fault. Is there more to running than just putting one foot in front of the other?
Aerobic Cross Training for Weight Loss
Do you sometimes get bored with your aerobic exercise? Do You sometimesfeel like you're not getting the resultsyou should from your aerobic exercise?If so, then aerobic cross-training isfor you.
Your heart is between one to two times the size of your clenched fist. Contrary to popular belief, it is not located to one side of the body - it is located almost in the exact center of your chest. Due to the shape of the heart and chest cavity, the heart pounds against the chest wall on your left side, so the heart rate is stronger when felt there. Your heart is responsible for pumping about six quarts of blood throughout your body, with about the same amount of force that the average person applies when squeezing a tennis ball. The heart is not under voluntary control. A system known as the autonomic nervous system, which includes the sympathetic and parasympathetic nervous system, is responsible for regulating your heart rate.
