Struggling with chronic knee pain or joint stiffness, but still want to stay active and get a great workout? In this episode, we dive into why taking to two wheels might be the single best thing you…
I love that analogy, and you know, the contrast between biking and other popular forms of cardio is just striking when you look at the physics.
Okay, so let's unpack that.
Yeah.
Because if running is essentially like taking a hammer to your joints, biking is basically suspending them in a localized anti-gravity field, right?
That visual is spot on because, um, to really appreciate biking as a therapeutic tool-
Mm-hmm
... we have to look at how our bodies handle gravity.
Running is the perfect example.
Right, because of the impact.
Exactly.
Hmm.
Every single time your foot leaves the ground and lands again, you're creating a collision, and those forces don't just stop at the soles of your feet.
Oh, they travel up, right?
Yeah.
They reverberate up through the bones of your ankles-
Mm
... crash into your shins, travel through your knees, and all the way into your lower back.
Yikes.
The source material brings up a statistic that really puts this into perspective.
Running on solid pavement subjects your knee joints to an impact force equivalent to three to five times your total body weight.
Wait, really? Three to five times?
Every single footfall, yes.
So if someone weighs, um, say, 200 pounds, their knees are absorbing up to 1,000 pounds of force every time their sneaker hits the concrete?
Exactly.
When you multiply that by, I mean, thousands of steps in a single run, that is just brutal.
