How to keep training when your joints hurt

The short answer: for most joint pain that isn’t a fresh injury, the fix is to change the movement rather than stop moving. Shorten the range, lighten the load, slow it down, swap the angle — then keep training. Resistance training has been shown to reduce pain and improve function in people with knee and hip osteoarthritis, which means the joint you’re protecting is often the joint that benefits most. The skill you need is telling acceptable discomfort apart from a stop-signal, and this page is mostly about that distinction.

Who this is for

You have a joint — knee, shoulder, hip, lower back, wrist — that complains during or after training. It has been going on for weeks or months rather than hours. You’ve been diagnosed with osteoarthritis, tendinopathy, or “wear and tear,” or you’ve been diagnosed with nothing at all and it simply hurts.

This is not for you if the pain arrived suddenly with a specific incident, if the joint is hot, visibly swollen, or locking, if you can’t bear weight, or if you’ve had joint surgery in the last three months. Those are clinician conversations first. See the last section.

What you need

Less than you’d think.

• A way to make a movement easier that isn’t just “lighter weight” — usually a box, a bench, a wall, or a pair of blocks.
• Something to load with that adjusts in small increments. Dumbbells, bands, or a backpack with books all work better here than a fixed barbell, because the useful jumps are small.
• A note on your phone. Two lines per session: what you did, what the joint did the next morning. This is the actual instrument. Pain that day is noisy; pain 24 hours later is the signal.

The plan

Step 1: Find the pain-free range

Take the movement that hurts and cut it in half. A squat that hurts at depth becomes a squat to a high box. A press that hurts overhead stops at forehead height. A hinge that hurts at the floor stops at the knee.

You are looking for the range where the movement is comfortable or close to it. That range is your training zone. It is not a consolation prize — loading a short range builds strength in that range, and the range itself has been shown to expand over weeks in most people as tissue tolerance improves.

Step 2: Set the load by the 0–10 rule

Rate the joint during the set on a 0–10 scale, where 0 is nothing and 10 is the worst you can imagine.

During the set	What it means	What to do
0–3	Acceptable	Continue. This is the working zone.
4–5	Borderline	Finish the set, then reduce load or range next set.
6+	Stop-signal	End the set. Change the movement, not the willpower.

Then check the next morning. If the joint is back to its normal baseline within 24 hours, the session was appropriate — even if it grumbled during. If it is worse for more than 24 hours, the dose was too high. Reduce by roughly 20% and repeat that session before advancing.

This 24-hour rule is the whole framework. Everything else is detail.

Step 3: Slow the tempo before you drop the weight

Most people reach for lighter weight first. Try tempo first. Three seconds down, one second pause, one second up gives you the same training stimulus at a noticeably lower load and removes the fast, high-force transitions that irritate most joints.

Speed is what hurts more often than weight is.

Step 4: Train the joint above and below

A painful knee usually involves a hip that doesn’t extend and an ankle that doesn’t bend. A painful shoulder usually involves a stiff mid-back. You don’t have to solve this to keep training, but adding two sets of hip or thoracic work per session is cheap and research suggests it helps.

Step 5: Keep the rest of the body training normally

This is the most commonly skipped step and the most valuable. A sore right shoulder is not a reason to stop training your legs, your left side, or your grip. Detraining everything because one joint is unhappy is how a six-week problem becomes a six-month one.

Single-limb work on the unaffected side is worth the effort in its own right: training one limb has been shown to produce modest strength gains in the untrained limb, an effect researchers call cross-education.

Step 6: Build a session you can actually repeat

A workable joint-friendly session, twice a week:

1. Five minutes of easy movement through the ranges you’ll use. Not stretching — just moving.
2. One lower-body push in your pain-free range. 2–3 sets of 8–12.
3. One upper-body push or pull in your pain-free range. 2–3 sets of 8–12.
4. One hinge or carry. 2 sets.
5. Two sets for the joint above and below the painful one.

Twenty-five minutes. Repeat it until it’s boring, which is a sign it’s working.

Progression

Progress the variable that isn’t the painful one. In rough order of how well irritable joints tolerate them:

1. Add reps in the same range at the same load. 8 → 10 → 12.
2. Add a set. Two becomes three.
3. Add range. Lower the box an inch. This is often the most satisfying progression and the one people forget is a progression at all.
4. Add load. Last, and in smaller steps than you’d use on a healthy joint — 5% rather than 10%.

Advance one variable at a time and hold it for two sessions before the next change. If the 24-hour check goes bad, step back one notch, not all the way to zero.

Expect this to be slower than training a joint that doesn’t hurt. Months, not weeks. That is the normal timeline, not a sign you’re doing it wrong.

Common mistakes

Treating pain as damage. Pain and tissue damage overlap less than intuition suggests, particularly in long-standing joint pain. Discomfort in a stiff joint under moderate load is usually not injury in progress. This does not mean pain is imaginary — it means pain is a poor odometer.

Resting completely and waiting for it to clear. Extended rest reduces load tolerance, so the joint hurts sooner when you return, which suggests more rest. That loop is the single most common way people lose a training habit in their fifties.

Only stretching it. Stretching a painful joint feels productive and occasionally helps in the moment. Strength around the joint is what shifts the trajectory. Do both if you like, but don’t mistake the first for the second.

Chasing the perfect diagnosis before starting. Imaging findings correlate loosely with symptoms — a substantial share of people with no pain at all show degenerative changes on scans. Useful for ruling things out, weak as a training guide.

Going hard on good days. The best-feeling day is when people overshoot, and the flare arrives 36 hours later. Keep the ceiling the same regardless of how good you feel.

Adaptations

If a specific joint is the problem

• Knee. Raise the surface you sit down to. Widen your stance. Favor split-stance work over deep bilateral squats. Leg press and box squats often tolerate load that free squats won’t.
• Shoulder. Move pressing to a neutral grip and stop below the painful angle. Favor rows and pulls, which most irritable shoulders tolerate better than presses. Avoid behind-the-neck positions entirely.
• Hip. Reduce depth and turn the toes out slightly. Hinges with a shorter range often feel better than squats. Carries are usually well tolerated.
• Lower back. Hinge with a lighter load and a shorter range, keep the spine in a neutral position you can hold, and use carries and split-stance work rather than heavy bilateral lifts while it settles.
• Wrist or elbow. Change the grip before anything else — neutral handles, straps, or a thicker grip. The load is often fine; the wrist angle isn’t.

If you have limited time

Two 20-minute sessions per week is a legitimate program. Pick one lower-body movement, one upper-body movement, and one carry. Do 2–3 sets of each. Skip everything else without guilt.

If you have no equipment

Body weight against gravity is adjustable by angle, and angle is free. Sit-to-stands from a higher chair, push-ups against a counter, step-ups onto a low stair, and carrying two grocery bags for two minutes cover most of what you need. Make it harder by lowering the surface or slowing the tempo.

Water-based work is worth mentioning: it unloads joints while still providing resistance, and research suggests it reduces pain in people with hip and knee osteoarthritis. It is a decent bridge, though it loads bone less than land-based training does.

What “working” looks like

Set the expectation correctly, because the wins are unglamorous.

• Weeks 1–2: Nothing much changes. You’re establishing that the sessions don’t cause flares. That is the entire goal.
• Weeks 3–6: The 24-hour check gets quieter. You notice you’re using a slightly deeper range without deciding to.
• Weeks 8–12: Load or reps have gone up. The joint’s bad days are less bad, and there are fewer of them. Stairs, floors, and getting out of cars stop registering as events.

The realistic outcome is a joint that hurts less often and tolerates more, not one that goes silent. Many people train productively for decades with a knee or shoulder that has an opinion. Notice frequency and function, not the presence or absence of sensation.

If eight weeks of consistent, well-modified training produces no change at all in any of those markers, that’s useful information — bring it to a clinician rather than adding volume.

When to talk to a clinician

Get assessed before continuing if any of these apply:

• Pain that arrived suddenly with a specific incident, or that you’d rate above 6 out of 10 at rest.
• A joint that is hot, red, or visibly swollen, especially with fever.
• Giving way, locking, or catching.
• Numbness, tingling, or weakness travelling down an arm or leg.
• Night pain that reliably wakes you, or pain accompanied by unexplained weight loss.
• Any joint replacement or surgical repair in the last three months.
• Pain that is steadily worsening across four to six weeks of sensible modification.

Also worth a conversation, less urgently: if you have inflammatory arthritis, osteoporosis, or take medication that affects bleeding or bone, the sensible starting ranges differ from the general case. A physiotherapist can usually give you specific modifications in one or two visits, which is a better use of a session than a general clearance.
