Explanation

Exercise and physical activity fall into four basic categories. Endurance, strength, balance and flexibility.
Endurance or aerobic activities increase the breathing and heart rate. They keep the circulatory system healthy and improve overall fitness.
Strength exercises make the muscles stronger. They help to stay independent and carry out everyday activities such as climbing stairs and carrying bags.
Balance exercises help to prevent falls which is a common problem in older adults. Many strengthening exercises also improves balance.
