We all know that exercise is very important in our daily lives, but we may not know why or what exercise should we do for us.

It's important to remember that we have evolved from nomadic ancestors who spent all their time moving around in search of food and shelter, traveling large distance on a daily basis. Our bodies are designed and have evolved to be regularly active.

So I will tell you 10 benefits of exercise.

There are many benefits of regular exercise and maintaining fitness and these are 10 benefits:-

1. Exercise increases energy levels

     Exercise improves both the strength and the efficiency of our cardiovascular system to get the oxygen and nutrients to our muscles. When our cardiovascular system works better everything seems easier and we have more energy for the fun stuff in life.

2. Exercise improves muscles strength.

     Staying active keeps muscles strong and joints, tendons and ligaments flexible, allowing us to move more easily and avoid injury. Strong muscles and ligaments reduce our risk of joints and lower back pain by keeping joints in proper alignment. They also improve coordination and balance.

3. Exercise can help us to maintain a healthy weight.

    The more we exercise, the more calories we burn. In addition, the more muscle we develop, the higher our metabolic rate becomes, so you burn more calories even when you're not exercising. The result? We may lose weight and look better physically which will boost our self-esteem.

4. Exercise improves brain function.

    Exercise increases blood flow and oxygen levels in the brain. It also encourages the release of the brain chemicals (hormones)that are responsible for the production of cells inthe hippocampus, the part of the brain that controls memory and learning. This, in turn, boosts concentration levels and cognitive ability, and helps reduce the risk of cognitive degenerative diseases such as Alzheimer's.

5. Exercise is good for our heart.

     Exercise reduces LDL cholesterol(the type that clogs our arteries), increases HDL (the good cholesterol) and reduces blood pressure so it lowers the stress on your heart. Added to this, it also strengthens our heart muscle. Combined with a healthy diet, exercise lowers the risk of developing coronary heart disease.

6. Regular exercise lowers our risk of developing type 2 diabetes.

     Regular exercise helps to control blood glucose levels, which helps to prevent or delay the onset of type 2 diabetes. Additionally exercise helps to prevent obesity, which is a primary factor in the development of type 2 diabetes.

7. Exercise enhances our immune system.

     Exercise improves our body's ability to pump the oxygen and nutrients around our body that are required to fuel the cells that fight bacteria and viruses.

8. Staying active reduces the likelihood of developing some degenerative bone diseases.

     Weight bearing exercise such as running, walking or weight training lowers our risk of both osteoarthritis and osteoporosis the adage of "use it or lose it " really does apply to bones.

9. Exercise may help to reduce the risk of certain cancers.

     Being fit may mean that the risk of colon cancer, breast cancer and possibly also lung and endometrial cancers are reduce. Studies by the Seattle cancer Research center have suggested that 35% of all cancer deaths are linked to being overweight and sedentary.

10. Exercise improves our mood and gives us an improved sense of well-being.

1.        Physical activity stimulates the release of endorphins which make us feel better and more relaxed. These in turn improve our mood and lowers our stress levels.
