More reasons to focus on building lean body mass, not losing weight and fat per se. The health benefits of maintaining and improving your muscle mass are many… watch this video and see what I mean:

Other than the reference to those over 45 being “older” people, this is a great article with encouraging news for adults who’d rather stick with their favorite impact exercises and save the silver sneakers for – well, someone else!
Thanks for sharing the link Dawn! (Key parts of blog captured below).
Is there any scientific study to substantiate the claim that older people (over 45) should limit high impact exercises such as jogging, sprinting, etc.?
…There is also little evidence to support the widespread belief that high-impact exercise speeds the onset of arthritis. In a 2013 study, adult runners, including many aged 45 or older, had a lower incidence of knee osteoarthritis and hip replacement than age-matched walkers, with the adults who accumulated the most mileage over the course of seven years having the lowest risk, possibly, the study’s author speculated, because running improved the health of joint cartilage and kept them lean as they aged. Similarly, a 2006 review of studies about jogging and joints concluded that “long-distance running does not increase the risk of osteoarthritis of the knees and hips for healthy people who have no other counter-indications for this kind of physical activity,” and “might even have a protective effect against joint degeneration.”
Running and similar high-impact activities likewise have a salutary effect on bone density, said Dr. Michael Joyner, an exercise physiologist at the Mayo Clinic in Rochester, Minn., and an expert on aging athletes, of whom he is one. Over all, he continued, he is “skeptical” of the idea that older people should avoid high-impact activities. “A lot of concerns about age-appropriate exercise modalities have turned out to be more speculative than real over the years,” he said, adding that during his research and personal workouts, he’s seen many seasoned adults pounding the pavement without ill effects.
The general public consensus is that we lose muscle mass (size and strength, too) as we age. But there are notable exceptions to the rule — athletes who have performed exceptionally well into their 70’s and even 80’s. See the World master’s rankings. For example, in the 2012 10K rankings list there are 38 runners age 60 to 85 that ran the 10K in less than 40 minutes, including the US runner, Nolan Shaheed (35:26 10K, 60-65 age group) who has age group records at several distances.
Well known triathlete coach Joe Friel just posted in his blog an article about maintaining muscle mass and the notion that we are destined to lose muscle. He reviews the latest studies that actually show little or no muscle mass loss is due to aging. What, you say? There are athletes that maintain muscle mass well into their 70’s, the key is that they work at it. See the photo from coach Joe Friel’s blog at the right. The middle muscle scan photo is a stark reminder that we are too sedentary in our lives. From sitting at our desks for 8-10 hours all day then watching TV for 3-4 hours at night. How many of us do 1-2 hours of strenuous activity each day, or even 30 minutes as recommended? Less than 3% of the US population according to some studies I have seen.
There’s a second aging/sedentary lifestyle issue here, not only does a sedentary lifestyle cause you to lose muscle mass, it also causes the loss of nerve control of the muscles. Older, sedentary people have less nerve connections to their muscles, thus can’t recruit the muscles they have.
Just another brick in the wall of information that says that we must keep moving, keep exercising, keep the intensity up, and just don’t sit around. Guess I’ve been right to keep that big commercial walk-behind mower for the last 20 years. I’ve always joked that it was my exercise program — 2-3 hours a week of walking at 3 MPH in tight circles.
Just Keep moving!
