The headline truth
Most joint pain isn’t from “using your joints too much.” It’s from using them the same way, for too long, without enough quality strength. Cartilage isn’t a fragile cushion; it’s living tissue that thrives on the right kind of pressure. Think “irrigation,” not “erosion.”
How joints actually get fed
Cartilage doesn’t have its own blood supply. It eats by soaking up synovial fluid—the slick liquid inside your joints.
When you load and unload a joint with control, you create a pump: fluid moves in and out, delivering nutrients and clearing waste. No load = stale fluid. Smart load = fresh delivery.
Concrete picture: a sponge in a bowl. Squeeze → old water out. Release → new water in. Your knees and spine want that cycle.
What “smart load” looks like
- Slow lowers, solid positions. Two–three seconds down, no bouncing.
- Range you can control. Not trying to hit Instagram depth if your hips aren’t ready.
- Often, not heroic. A few clean sets, multiple days per week, beats wrecking yourself once.
- Progress you can feel. A bit more range, a bit more control, a bit more load—over weeks.
This is joint training, not punishment.
Knees: why squats help (and how to make them feel good)
Your knee is happiest when your hips, quads, and calves share the work. Squats teach that.
If your knees bark during squats, try this:
- Elevate heels on small plates or a wedge. It lets the knee track forward without your back stealing the job.
- Goblet hold (dumbbell at chest). It keeps your torso upright and center of mass balanced.
- Shorten the depth to what’s clean today. Earn more range with time.
You’re not avoiding knee motion—you’re owning it.
Backs: why hinges help (and what “bracing” really means)
Backs hate being the only thing doing stability duty. A hinge (think Romanian deadlift) teaches your hips to drive and your core to support.
“Brace” doesn’t mean clench everything. It means breathe into your lower ribs, keep your torso stacked, and move from the hips. Controlled reps build the scaffolding your spine loves.
Tendons: the quiet part people miss
Painful tendons (patellar, Achilles, hamstring) usually dislike spikes, not work. They adapt to consistent, tolerable tension.
Slow eccentrics (lowering) and brief isometrics (holds) give tendons time under load without chaos. Translation: they get tougher and less reactive, so stairs, runs, and squats feel safer.
“But my MRI says I have wear and tear.”
So does every adult’s. Imaging rarely predicts pain by itself. What does predict feeling better?
- Getting stronger in the patterns you use daily.
- Improving range you can control.
- Reducing big spikes in activity and replacing them with steady, repeatable work.
We’re building capacity, not chasing perfect pictures.
Real-life wins you’ll notice
- Stairs stop feeling like a tax.
- Car rides no longer glue your back.
- Pick-ups (kids, bags, boxes) feel automatic, not risky.
- Walks and runs land softer because your legs share load better.
Same life, better distribution.
What to do this month (simple guardrails, not a plan)
- Train patterns, not body parts: squat, hinge, push, pull, carry.
- Keep reps clean and controlled. If form slips, the set is over.
- Choose loads that feel challenging but leave 1–2 reps in the tank.
- Show up 2–3 days per week. Frequency feeds joints; ego sessions don’t.
If pain flares, adjust the variation, not the mission: goblet instead of barbell, split squat instead of back squat, hip hinge with dumbbells instead of a heavy bar. Keep the pump. Keep the progress.
When to get help
Sharp pain, night pain, or anything that’s getting worse despite dialing things down? See a clinician who understands strength, not just rest. The goal is the right load, not no load.
Take-home
Cartilage likes load. Tendons like time under tension. Joints like options.
Lift with control, lift often, and let your body practice sharing the work. The fear fades. The strength sticks. And your knees and back finally feel like they’re on your side.
