Why Is Exercise Important? | 12 Reasons You Should Know

We all know that exercise is important, but do we understand all the reasons why? There are many benefits to regular exercise – probable more than you are aware of. Read on to find out 12 key reasons why exercise is important.

12 Reasons why exercise is important

  1. Exercise helps weight management

This one is probably no surprise. Exercise helps you burn energy and calories and in doing so is a great weapon for weigh loss and weight management. In fact, it’s proven through studies like this that regular exercise helps to increase your metabolic rate - a pre-cursor for burning more calories.

Regular exercise is most effective at supporting weight management when supported by a healthy, balanced diet. It’s no good going on a 5 mile run every day only to eat 6,000 calories of pizza when you get home. Try to support exercise with an intake of the right nutrients.

The average man needs 2,500 calories a day to maintain his weight. Exercise will burn calories and so can eat more on the days you exercise and still maintain your weight. For example, if you burn 400 calories at the gym, then you can eat 2,900 calories that day and maintain your weight.

If you are looking to lose weight then you need more exercise, to eat fewer calories or a combination of both. If you are looking to gain muscle, then you will need a surplus of the right type of calories in order for your body to grow.

  1. Exercise Improves Mood

Exercise can be so effective at improving your mood that there are studies showing that it can be as effective as anti-depression medication in helping mild or moderate depression.

  • Exercise increases levels of serotonin
  • Exercise increases levels of endorphins
  • Exercise reduces chemicals in the immune system
  • Exercise helps lower stress (see point 12)

If you need a boost to your mood, then exercise is one of the best tools available to help.
