Isn't it great to know that a little exercise can help change all that? Regular exercise slows the aging process, so you lose less muscle and your joints stay flexible and strong.
Regular exercise also helps strengthen your heart, lower your blood pressure, control your blood sugar and cholesterol, maintain your bone density, and control your weight.
Exercise for Your Age
The three main types of exercise are flexibility exercise, aerobic or cardiovascular training, and strength training. The average person should have a 2-1-1 ratio of flexibility exercise to cardio training to strength training. But to do the best workout possible for your body, you'll have to adjust the ratio of these exercises for your special needs -- and those needs can change with age.
The RealAge benefits of cardiovascular exercise persist throughout the years, but they are greatest when you are younger. Burning between 2,000 and 3,500 calories per week with cardiovascular exercise makes your RealAge as much as:
1.9 years younger at age 35
1.7 years younger at age 55
1 year younger at age 70
So as you get older, it's okay to devote a larger percentage of your workout to other types of exercise, such as strength training or flexibility exercise. Walking on a smooth surface is a great cardio exercise for older adults.
Because people often lose muscle as they age, the older you get, the more important strength training becomes. And the RealAge benefits increase as you get older. Engaging in strength-building exercise for more than 30 minutes per week can make your RealAge as much as: 1.5 years younger at age 35
1.8 years younger at age 55
1.9 years younger at age 70
As people age, balance and flexibility exercises become increasingly important because they can help reduce frailty and the risk of falls. They also help with routine activities such as rising out of a chair, as well as more complex activities such as lifting and reaching when gardening or playing golf. Are you losing your balance? Take this quick self-test and find out.
Keep It Safe
Whatever your daily workout holds for you, be sure to start with a brief warm-up to help your muscles and joints ease into exercise; and stay well hydrated throughout your workout. Exercise must be safe for it to truly do your body good.
