How to Train Around a Knee That Hurts

• Pain above a three out of ten is your signal to change the exercise, not push through.

• Upper body and core work keeps momentum going while your knee settles down.

• Swimming and cycling usually load the knee far less than running or squatting does.

A sore knee is not a reason to stop moving altogether. It is a reason to stop doing the specific things that make it worse, and find what doesn't. That distinction matters, because a week on the sofa rarely helps a knee feel better. It just adds deconditioning on top of pain. The first thing to do is honest self-assessment. Is it sharp pain during movement, a dull ache after, or swelling that won't go down? If you have significant swelling, a locked joint, or pain from an injury you remember happening, see a GP or physiotherapist before you do anything else. That is not throat-clearing caution — that is just the right call. For the far more common scenario — a knee that grumbles, tightens up, or aches during certain movements — you almost certainly have more options than you think. The rule most physios use in practice is this: if pain stays below three out of ten during an exercise and doesn't worsen afterwards, that exercise is likely fine to continue. Above that, swap it out. Not forever. Just for now.

Heavy barbell squats and lunges are usually the first things to drop. Running on hard surfaces tends to follow. Anything that requires full knee flexion under load — think leg press with a deep range, step-ups with a big step — is worth questioning. None of that means your training falls apart. Upper body work is almost always unaffected. Bench press, rows, pull-ups, overhead pressing, farmer's carries — carry on. Your upper body doesn't know your knee hurts. Core work — planks, dead bugs, pallof presses — is usually fine too. For lower body, you look for the load and range that doesn't provoke symptoms. Shallow squats often feel fine when deep ones don't. A box squat to a higher box takes the bottom range away. Split squats hurt some knees and not others — try them before you write them off. Hip-dominant work frequently becomes your best friend here. Romanian deadlifts, hip thrusts, glute bridges, cable pull-throughs. These load the posterior chain heavily with far less compressive force on the knee. Many people find they actually build better glute and hamstring strength during a knee flare-up than they did before, because they're forced off the squat rack and onto movements they'd been avoiding.

Running is often the first casualty and the one people miss most. If the treadmill or the road is aggravating things, you have real alternatives. Cycling — stationary or outdoor — tends to be much kinder to the knee than running because the impact is gone. Seat height matters: too low and you add compressive load, so raise it until there's a slight bend at the bottom of the pedal stroke. Swimming is probably the lowest-load cardio option available. If your knee hurts in water, something is quite wrong and you should get it seen. A rowing machine divides opinion. For some people it's fine; for others the flexion involved is too much. Try it cautiously and pay attention to how it feels during and the morning after. The same goes for the cross-trainer, which is often more tolerable than running but still involves knee flexion. Parkrun isn't going anywhere. You can volunteer on the weeks you can't run, which keeps you in the habit of Saturday morning movement without logging five kilometres on a complaining joint.

The most common mistake is returning to full training the day the knee feels normal. One pain-free day is not the same as a recovered knee. The tissue that was irritated hasn't necessarily had time to adapt. A better approach is to add load and range back gradually — a few extra degrees of squat depth per session, a little more weight, a slightly longer run. If symptoms stay quiet across three or four sessions, you're moving in the right direction. Don't test the knee by doing a full session on it to 'see how it goes'. That is rarely how it goes well. Keep a simple log — even just a note on your phone — of what you did and how the knee felt that evening and the next morning. Motivaite's daily check-in is useful here because it gives you an honest record rather than the selective memory most people have about their training. The bigger picture is this: most knee pain in people who are active is manageable with some short-term adjustment and patience. It doesn't usually mean permanent modification. But the people who recover best are the ones who adapted during the painful period rather than stopped entirely — because they kept their strength, kept their habits, and had less distance to travel to get back.

Often yes, but not in the way you were squatting. A higher box squat, a narrower or wider stance, or a goblet squat with reduced depth will each change the demand on the knee substantially. Try variations and pay close attention to pain during and soreness the following morning. If everything provokes it, leave squatting alone for a week and focus on hip-dominant work instead. That is not defeat — it is just sensible prioritisation.

A sleeve can provide warmth and compression that some people find genuinely helpful during training. It doesn't fix anything structurally, but if it lets you train with less discomfort then there's no harm in using one. An off-the-shelf brace is a different matter — most active people don't need one unless a physio or doctor has recommended it for a specific reason. Don't use either as a reason to push through pain that's telling you to back off.

That depends entirely on what's causing the pain, which is why this guide can't give you a timeline. What most people find is that modifying training rather than stopping it gets them back to full training sooner, not later. If pain is not improving after a few weeks of sensible modification, or if it's getting worse, see a GP or physiotherapist. That appointment is more useful than any guide.
