Real talk on bodies that work for a living, a newsletter from The Working Body

Why nothing you've tried for sore knees seems to stick.

A straight answer for guys who've been working through it for years

You don't need anyone to tell you something's wrong.

You feel it on the first step out of bed and the first climb of the day. Your back reminds you on the drive home.

And you haven't just sat there complaining. You've tried things, probably most of what's below.

The problem is that almost all of it was built to get you through today. Not much of it does anything for the next ten years.

What you've probably already tried

Pushing through it.

It's worked for a long time, and nobody can say you're not tough.

But pushing through only gets you to the end of today's shift. It doesn't give your body anything to work with tomorrow. It just borrows from tomorrow.

Advil, Aleve or whatever's in the glovebox.

It gets you through the shift. That's what it's for.

It isn't made to give your joints and connective tissue what they're built from. Those are two different jobs.

Better boots, knee pads and gel insoles.

That's money well spent. Good gear is one of the smartest things you can buy in this trade. Anyone who says otherwise has never knelt on concrete for eight hours.

But gear does one job. It takes some of the hit while you're working. It does nothing for the part of you that's been taking the hit.

Think of it like new tires on your truck. They smooth out the ride, but they don't do anything about the wear that's already on the frame.

And when the boots come off at night, the protection comes off with them. What your knees and back went through that day doesn't.

Heat pads, ice packs and braces.

They're fine for a rough night. But they work from the outside, and the wear is on the inside.

Stretching.

Good. Keep doing it. Anyone who tells you to quit stretching doesn't know what they're talking about.

But be honest about how it went. You probably found a video and did it every morning for a week or two. Then a 5 a.m. call-out hit, or a 14-hour day, and that was the end of it.

Even on the weeks you kept it up, stretching does one job: it loosens you up. Think of a worn rope. Stretching keeps the rope loose. It doesn't do anything about what the rope's made of.

Glucosamine.

Maybe you took it for a few weeks, didn't notice anything and quit. That's fair. Most guys do.

There are usually two reasons:

It only covered one piece. One ingredient does one job.
You didn't stick with it long enough. This doesn't work like a headache pill. It takes weeks of taking it every day. Nobody told you that, so it looked like it wasn't working.

Why it keeps catching up with you

Your tendons, ligaments and cartilage are built largely from a protein called collagen. It's the rebar in the concrete.

Your body starts making less of it in your mid-20s, and it makes a little less every year after that.

So at 40, you've got twenty years of hard work on your body and less collagen to work with than you had at 22.

That's the gap. Pushing through doesn't close it. A painkiller doesn't close it, and neither does stretching.

Two things a day, about 30 seconds total

Anvilcore covers two jobs in one kit:

☕ Collagen peptides plus vitamin C. Put one scoop in your coffee or water bottle. It's chocolate-flavored. The collagen peptides provide raw material, and the vitamin C helps your body form collagen normally.

💊 Turmeric & Boswellia Serrata. Take one capsule with lunch. It supports joint health and mobility. It's paired with black pepper extract for absorption.

It's a simple daily habit that fits into what you already do: the scoop goes in your coffee and the capsule goes with lunch.

Here's what we'll tell you up front

It's not a painkiller. Keep whatever gets you through a bad day.
It won't undo 20 years of hard work. It supports the body you've got now.
It's maintenance, like an oil change. You keep doing it. It's not a one-time repair.

Collagen powder and turmeric capsules kit

What customers are saying

I have been taking these for a few days now. I immediately noticed a positive difference with regard to my aches and pains. I plan on purchasing more! They recommend you take one scoop of collagen and 3 pills daily with meals.

I take 3 capsules 3 times daily due to intense amounts of inflammation and this works for me! Now I don’t feel like I’m in a straight jacket anymore. I can move my joints around freely instead of constantly spraining muscles just to barely move them. No side effects from the supplements. Thank goodness!
