The word aerobic literally means “with oxygen” or “in the presence of oxygen.” Aerobic exercise is any activity that uses large muscle groups, can be maintained continuously for a long period of time and is rhythmic in nature. Aerobic exercises utilize oxygen as the major fuel for sustaining activity for relatively long periods.
In general, aerobic exercises are those activities that require large muscle work, elevate the heart rate to between 60 percent and 80 percent of maximal heart rate, are continuous in nature and are of 15 to 60 minutes in duration. An aerobically fit individual can work longer, more vigorously and achieve a quicker recovery at the end of the aerobic session.
Aerobic exercises fall in two categories:
Low to Moderate Impact aerobics ?These include walking, swimming, stair climbing, step classes, light water aerobics, rowing and cross-country skiing. Nearly anyone in reasonable health can engage in some low- to moderate-impact exercise. Brisk walking burns more calories than jogging for the same distance because it takes more time to walk than jog that distance and poses less risk for injury to muscle and bone. Read more…
Abdominal exercise devices are many in number and range form simple inflatable balls to complicated structures with springs hinges and hydrolic resistance mechanism.
The Exercise equipment industry also recognises the the motivation for many people to exercise is to reduce a growing layer of fat around the mid-section, so an obvious choice for any one looking to loose weight in this area would choose a device to directly taget this area.
Althogh this strategy seems to be logical, the effectiveness of an abdominal exercise device on the abdominal area is much less than one would think, in fact the effects of abdominal exercises are far less than that of walking, jogging or cycling for a similar level of perceved effort. The fact that most abdominal exercise devices use a muscle isolation form, will give a far greater feeling of a good workout because the lactic accid build up during exercise causes some discomfort which is normaly ascociated with vigerous exercise and thus giving a percieved level of exercise which has actually not depleted the normal level of blood sugar in the bodies energy system and thus not effected the bodies energy system to break down stored fat into usable energy.

There’s good news for people who want to watch their weight without giving up watching TV. Now there’s a new workout for couch potatoes and people who think they’re too busy to find time to stay fit.
With time at a premium, many Americans are turning to creative forms of exercise. In a recent survey conducted by Harris Interactive for the North American Spine Society, three out of four people said they used the stairs rather than the elevator at work, 58 percent said they started parking their cars far away in parking lots and almost half reported walking while on the phone.
At the same time, however, 46 percent of people described themselves as couch potatoes–a major contributing factor to being overweight. Many adults say they have procrastinated working out in order to do other activities, such as watching television, sleeping in, doing household chores or working.
Approximately three in four adults say they would exercise more if they could fit it into their daily routines, however, and a majority of adults say they would exercise more often if they could do it at home. Among noncouch potatoes, 80 percent would like to get more exercise, but say they don’t have the time. Read more…
