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.

High-Impact aerobics – Activities that belong to this group include running, dance exercise, tennis, racquetball and squash. High-impact aerobics should be performed on alternate days. People who are overweight, elderly, out of condition or have an injury or other medical problem should do them even less frequently and only with clearance from their doctor.

Here are some of the many aerobic exercises you can do and because of the variety you have to choose from, it can not only take the bordum out of doing it, it can make doing it downright fun as well.

1. Walking
Walking is a popular form of exercise because it requires little in terms of equipment or facilities. Walking an extra 20 minutes each day will burn off 7 pounds of body fat per year. Longer, moderately-paced daily walks are best for losing weight.

Marvelous things happen beneath the skin in the heat of the sweat bath. The capillaries dilate permitting increased flow of blood to the skin in an attempt to draw heat from the surface and disperse it inside the body. The bather’s skin becomes cherry red. The heart is pressed into a faster pace to keep up with the additional demands for blood. Impurities in the liver, kidneys, stomach, muscles, brain, and most other organs are flushed out by the faster flow of juices. The skin and kidneys filter the wastes, excreting them in sweat and urine.

Exercise Your Heart!

Some researchers claim that the rapid flexing of the heart and blood vessels in the heat of the sweat bath is a healthy exercise that puts little more strain on the heart than strolling on level ground. The increased capillary volume, they say, keeps blood pressure normal. Other medical people, however, qualify their commendations. One Finnish study observed that whereas blood pressure of healthy persons remains approximately normal in a sweat bath, there occurs a marked reduction of pressure in persons suffering from high blood pressure. However, this effect is only transient,

How Hot Do We Get?

While the surface temperature of the skin may rise as much as 1O degrees C, inner temperature increases up to 3 degrees C. This is the “fever” that Hippocrates and generations of medical people after him sought, and is created as one reclines in a sweat bath! Of course it is unlikely that “every disease” can be cured by fever, but it is common knowledge that many bacterial and viral agents do not survive well at temperatures higher than normal body temperature. It is also possible that damaged cells repair themselves quicker in fever conditions due to the increased metabolic rate. Recovery from illness then comes easier and quicker.

Training at home could prove as a good solution for the ones interested. The effectiveness of this type of training could compare to the one of working out in the gym, as long as some factors are considered.

The first, and at the same time the most important of these, is owning the necessary equipment. If, besides this, you also have a partner who trains with you, the exercises can be as effective as the ones performed in the gym. Of course, we are talking now about the ideal situation of affording a gym in your own house.

Even with these conditions fulfilled, some practitioners, especially the more extrovert ones, might lack the stimulating atmosphere, the sharing of experience, the communication that they can find in the gym.

In most of the cases, what you can do at home is improvise a room or just a corner of a room, for fitness. Besides, most of the times you have to train by yourself. As these are the most frequent situations, we’ll deal with them now. Anyway, it is preferable to have constant training at home, rather than interrupt it a lot because the gym is too busy, too far, too expensive, etc.

The minimum of equipment necessary for training at home includes: an adjustable bench, a set of two dumbbells, with increasing weights, a barbell, with free weights and a fix bar for pull ups. This equipment will enable both executing basic exercises (squats, bench presses, pull-ups, sit-ups, etc.) and diversity of exercises, necessary for avoiding routine.

The main disadvantage of not having a partner to train with is reflected in the amount of loading in some exercises, which cannot reach its maximum. There are many exercises which can be loaded to maximum without any risk, even if there is no partner to assist you (pull-ups, dips, shoulder presses, barbell curs, dumbbell curls, etc.).

The benefits of a good strength training program are almost endless. Less disease, happiness and most importantly, showing off your muscles at the beach.

Strength training should be part of everyone’s routine. Even if you are low on time, strength training, according to the ACSM (American College of Sports Medicine), only needs to be done 2-3 times per week with each session lasting no more than one hour. For 2-3 hours per week, huge benefits can be realized.

Regular strength training will:

**help you in day to day activities around the house and in your yard. It will keep you independent which is especially important in the older population. Imagine not being able to lift a 5 pound bag of flour or take the garbage out by yourself.

**lower the risk of osteoporosis, hypertension and diabetes.
