Strength - A key to healthy aging
As we age our muscle strength declines at the rate of about 1 percent per year once we are in our 30's. This means that, unchecked, by the time we reach 70 our loss of strength can be large enough to restrict us from doing normal daily activities.
But your muscles, no matter your age, repond to exercise just like those of an Olympic athlete. People can get stronger through exercise even into their 90's.
Strength is a key component to healthy aging. And it is something that you can improve with a little work. Before you start a resistance exercise program be sure to see your GP to get the OK to do some moderate to vigorous activities.
There are many different programs that a qualified exercise professional can lead you through, but for the most part you just want to exercise the major muscle groups in the body - upper and lower body - against some resistance that you can lift 8 to 12 times at one go.
With some regular exercise the benefits can be very noticeable. Although not the true fountain of youth, regular resistance training can improve the muscle strength of a 70 year old to the equivalent of an average 40 year old!
Not only will you be stronger, but your efforts will make you steadier on your feet, less likely to fall and help maintain your bone strength as you age.
Don't let your age be an excuse for not lifting a few weights. You will experience the benefits with every step.
