Simple Keep Fit Exercises
What is a cardio exercise? Cardio is short for cardiovascular. It refers to the heart muscle. Cardio exercises raise your heart rate and keep it raised for a certain period of time. They are otherwise known as aerobic exercises.
The key to doing cardio work is to find some that you will enjoy and do them day in and day out.
Very intense cardio work can produce endorphins, the brain's natural happiness chemicals, and promote a sense of elation and wellbeing. This will increase the chance of the exercise being habit forming, just what you need when starting a new exercise program.
Some examples of cardio exercises are brisk walking, jogging, swimming, and cycling.
Depending on the type of cardio exercise used, many calories can be burned in a relatively short period of time.
Here is a website explaining different types of cardio exercises Shapefit.
The amount of calories burned during each cardio exercise depends on a number of factors:-
The intensity of the workout.
The time spent on each workout.
The body weight of the person undertaking the exercise.
There are probably some other factors, but the above are the major ones.
For instance, a 170lb man swimming a fast crawl can expect to expend 120 calories in a 10 minute interval.
As a comparison, only 14 calories are burned watching TV during the same 10 minute interval.
