Physical Fitness can be measured in various aspects such as your balance, stamina, strength and flexibility. Regular exercise makes you fit, gives a general sense of well-being, improves appetite and sleep and makes the heart and circulation, lungs and respiration work more efficiently.
Regular exercise is vital to help maintain good health. Exercise burns up extra calories in food and reduces the likelihood of these being converted into fat. Exercise carried out for at least about 20 minutes three times a week is beneficial for the body.
Research has shown that regular exercise 3 days a week gives a 15 percent boost in mental functioning.
