Healthy older adults should do four types of activities regularly: aerobic (or endurance) exercise and activities to strengthen muscles, improve balance, and increase flexibility. For any new physical activity, if you have not been active, start slowly and work up to your goal. To track your progress and stay motivated, keep a daily diary of what you do and how long you do it. Many activities give you more than just one benefit! Water aerobics with weights gives you strengthening and aerobic benefits. Yoga combines balance, flexibility, and strengthening. Choose what you like to do—some physical activity is better than none.
