Over the month of July, we’ll be diving into key aspects of joint health — from the importance of impact and movement, to how lack of use contributes to arthritis and joint replacements. In Week 4, we’ll take a look at the rising trend of weighted vests in exercise — the latest ‘fad’ that’s generating plenty of interest and debate.
When it comes to healthy joints, most people think of flexibility or avoiding pain. But one of the most underrated and essential factors for joint longevity is load, particularly weight bearing and impact. Joints are living tissue. They thrive when loaded appropriately and slowly weaken when consistently underused.
Dr. Vonda Wright, a renowned orthopaedic surgeon and advocate for active aging, puts it simply: impact is not the enemy — it’s the stimulus. Her research into older athletes shows that those who continue to place appropriate stress on their bones and joints not only maintain better mobility but also have stronger, more resilient joint tissues.
Weight bearing activities — like walking, hiking, jumping, or even squatting — stimulate the production of synovial fluid (the joint’s natural lubricant), encourage cartilage renewal, and signal bones to stay strong. These micro-stresses are like giving your joints a nudge that says, “Hey, stay alive and alert.”
So what kinds of impact are we talking about? Dr. Wright recommends simple, accessible movements that get your joints loading and responding. These include:
This kind of intentional impact is the opposite of careless pounding. It’s smart, deliberate, and crucial to keeping your joints responsive and alive.
Avoiding impact altogether, as many people do out of fear or poor advice, creates the opposite effect. Disuse breeds weakness. The joints begin to starve, literally — without pressure, they don’t get the nutrients and load they need to stay healthy.
Want better joints for life? Embrace weight. Embrace impact. Start light and build smart.
