It goes without saying that exercise is great for your body. But just how good does it get? Can it take you back in time? No, we’re not talking about time machines or magic, or even movies starring Michael J. Fox as Marty McFly. Consistent exercise can actually reduce your biological age – the age of the cells in your body. It will help you reduce the wear on your body, so by the time you turn 40, as an example, your biological age might only be 35 or even 31!

Not as much as you think hinges on the number of candles on your birthday cake. I’ve seen patients who were as vibrant at 63 as they were at 55, and others who were 55 and felt like they were 63! Our bodies are different, of course. But there are things we can do to stay youthful and feeling fresh, longer.

What Can You Do?

Even if you’ve never exercised before, it’s never too late to start. In fact, I encourage you to find a routine that works for your situation and gets you back in the groove! When you change your lifestyle for the better, your biological age starts to slow. For some people, it can even turn back the clock a bit. Studies show that the older you are, the easier it is to reduce your biological age with the help of regular exercise.

15 minutes of morning exercises aren’t sufficient, though. Work up your stamina so you can break a sweat. Talk to your physician about an appropriate recommendation to getting started. I like to recommend routines that are easy on the joints like biking, and walking. Dancing is even a favorite. The higher level of activities required to start reducing the biological age includes at least 30 minutes of brisk walking per day for women and 40 minutes for men.

After a session or two of great exercise, you’ll notice that you might sleep better – and rest is great for your health overall. Over the longer term, staying active helps you maintain a healthy weight, you might suffer from fewer colds, and you’ll feel sharper. In short, you’ll feel younger!
