How to program around a client's injury, without playing physio.
Nearly every client arrives with a history - an old knee, a cranky shoulder, a back that flares under stress. The coaches who handle it well are not the ones with the most rehab knowledge; they are the ones who know exactly where their lane ends. You work around what a professional has cleared, you regress instead of deleting, and you refer out the moment a symptom stops being trainable. That discipline is what keeps a client progressing and keeps you out of territory that belongs to a doctor.

General information for coaches, not medical advice. Injury assessment, diagnosis and rehabilitation belong with a doctor or physiotherapist.
the short version
As a coach you work around a client's injury; you never treat it. You can program for someone with a cleared or chronically managed issue by training what is pain-free, regressing range, load and tempo instead of removing whole movements, and autoregulating on rough days. Anything acute, new or undiagnosed goes to a doctor or physiotherapist first, and if that professional sets restrictions, you program inside them without overriding. The skill is knowing the line: diagnosis, rehabilitation and pain management are theirs; strength and conditioning around the injury is yours.
Know the lane before you touch the plan.
Everything in this guide rests on one distinction, so it is worth being blunt about it. A fitness or nutrition coach helps a client build strength, capacity and confidence. Diagnosing why something hurts, treating it, and rehabilitating it are medical acts that belong to a doctor or physiotherapist. When those two things blur - when a coach starts guessing at a diagnosis or prescribing rehab - the client is worse off and the coach is exposed. Keeping them separate is not a limitation on your coaching; it is what makes your coaching trustworthy.
What you can program around. An injury that has been assessed and cleared for exercise, or a chronic issue the client is already managing with a professional, is a coaching problem. You have information about what is safe, you have restrictions to work inside, and you can build a plan that trains everything the injury does not stop.
What you do not program around. New, acute, or undiagnosed pain is not yours to interpret. If a client cannot tell you what is wrong because no one has looked at it, the honest answer is not a modified program - it is a referral. The same is true for anything that is clearly getting worse or behaving in a way neither of you understands. Those belong with a professional first, and coaching resumes once the client is cleared.
Holding that line is easier when you say it out loud early. A client who hears "that part is for your physio, this part is where I can really help" trusts you more, not less. It signals that you know your craft well enough to know its edges.
The conversation does most of the work.
What to ask at intake. Before you write a single session, get the history. Ask what happened and when, whether a doctor or physiotherapist assessed it, and whether the client was cleared to exercise. Ask directly what they were told to avoid, and whether they are still under anyone's care. Capture this the same way you capture everything else at the start - a structured intake and assessment form makes sure the injury history is on the record instead of half-remembered from a first call.
Get the language right. Teach the client to distinguish pain from discomfort, because the words drive the decision. Sharp, sudden, or worsening pain is a stop signal. The dull, familiar ache of a muscle working, or mild stiffness that eases as they move, is usually the normal cost of training. You are not diagnosing anything by asking a client to describe what they feel - you are gathering the information that tells you whether to continue, regress, or refer.
What to track in check-ins. An injury is not a one-time note; it is a moving picture. Add a few fields to the regular check-in: where any symptoms sit, a simple pain or symptom rating, whether it is trending better or worse week to week, and which specific movements provoke it. Trends in those fields tell you when to add load and when to hold far more reliably than a single session ever will.
In Coachway, you can add custom check-in fields for exactly this - a symptom-location note, a pain rating, a better-or-worse marker - alongside the training you build and adjust in the client app, so an old shoulder or a managed back shows up as a tracked signal instead of a comment buried in a chat. The tracking makes the pattern visible; you stay the one deciding what to do about it, inside your lane.
Program the trainable, regress the rest.
Train what is trainable. An injured knee is not a reason to stop training; it is a reason to train everything else. Most injuries are local, and the pain-free menu is almost always larger than the client assumes. Program the uninvolved body hard and well, keep the fit engine running, and the injury becomes one constraint in a full plan rather than the reason the plan stops. The general principles of building a client workout program still apply - you are simply drawing the menu from what the client can do without symptoms. For a cleared knee in particular, our coaching breakdown of Ben Patrick's knees-over-toes approach for coaches shows how to build tolerance in the surrounding tissue without stepping into rehab.
Regress the pattern, do not delete it. Reaching for a completely different exercise every time something is tender teaches the client to fear the movement. It is usually better to keep the pattern and dial it back: shorten the range to the part that feels fine, lower the load, slow the tempo, or move to a variation the client tolerates. A squat that hurts deep might be a comfortable box squat; a painful overhead press might be a landmine angle. The pattern stays alive, and you have somewhere to progress back from. When the knee is the sticking point in a squat, our breakdown of Squat University's knee-pain guidance for coaches works through the same regress-don't-delete logic in more detail. For a client with a cleared, chronically managed low back, our coaching breakdown of E3 Rehab's low-back pain approach for coaches covers how to keep the hinge and trunk trainable without stepping into rehab.
Use isometrics as an entry point. When a movement is irritable, holding a position under tension is often better tolerated than moving through range under load. Isometrics give you a way to load the area, keep the client working, and build confidence without provoking symptoms, which makes them a useful first rung when you are easing a pattern back in. Treat them as a starting point you progress from, not a permanent parking spot.
Autoregulate on symptom days. Injuries do not read the training calendar. Give the client a clear rule for a flared-up day - reduce the range, drop the load, or swap to the pain-free version rather than pushing through or skipping the session entirely. Autoregulation keeps momentum on the bad weeks and stops one rough day from turning into a lost month.
Coach alongside the physio, never over the top.
When a client is under the care of a physiotherapist or doctor, that professional sets the boundary and you program inside it. Their restrictions are not suggestions to weigh against your own read - they are the frame. If they have said no loaded flexion for now, that is the constraint, and your job is to build the best plan that respects it, not to decide it is probably fine.
With the client's permission, a short line of communication makes everyone's job easier. Ask what has been cleared, what is off-limits, and roughly when they expect to progress the restrictions. If any of it is ambiguous, the answer is to have the client check with their clinician rather than to fill the gap with a guess. You are the strength and conditioning side of the team; the physiotherapist owns the injury. Played that way, the two roles reinforce each other instead of competing.
One rule holds above all the others: never override a medical professional's instructions, and never quietly reinterpret them into something you would rather do. If you think a restriction is holding the client back, that is a conversation for the client to have with their physio, not a call for you to make.
The red flags that end the session.
Part of good coaching is knowing when to stop coaching and hand off. If any of the following show up, pause the movement that provokes it and refer the client to a doctor or physiotherapist before continuing. None of these are yours to train through or explain away:
- New, sharp, or severe pain that appears during or after a session
- Swelling, heat, or visible change around a joint
- Numbness, tingling, pins and needles, or weakness that gives way
- Pain that wakes the client at night or is worse at rest than in movement
- A symptom that is clearly trending worse week over week rather than settling
- Any pain the client cannot connect to a known, cleared injury
Referring out is not an admission that you failed. It is the professional call, and clients read it that way - the coach who says "this one is for your physio, and I will build around whatever they tell you" is the coach they keep. Diagnosis, rehabilitation and pain management sit with the medical side, full stop. You adjust the training around it, honestly and well, and that is more than enough to keep a client moving.
Programming around injuries FAQ.
Can I train a client who has an injury?
Usually yes, when the injury has been assessed and the client has been cleared to train, or when it is a chronic issue they are already managing with a professional. What you do not train around is new, acute, or undiagnosed pain - that goes to a doctor or physiotherapist first. Your job is to program around what has been cleared, not to decide whether it is safe to load in the first place.
What do I ask a new client about a past injury at intake?
Ask what happened, when, whether they saw a doctor or physiotherapist, and whether they were cleared to exercise. Ask what movements or loads they were told to avoid, and get them to describe what they feel in their own words - sharp pain and dull discomfort are not the same signal. Record the answers so the plan starts from facts rather than guesses.
Should I stop training a body part completely if it is injured?
Rarely. Deleting a whole movement pattern usually costs more than it protects. The better move is to regress: shorten the range, drop the load, slow the tempo, or swap to a variation the client can do without symptoms. Keep the pattern alive at an intensity they tolerate and rebuild from there, while the rest of the body keeps training normally.
A client's physiotherapist gave them restrictions. Do I have to follow them?
Yes. When a client is under the care of a physiotherapist or doctor, their restrictions set the boundary and you program inside it. You never override a medical professional's instructions, add load they told the client to avoid, or reinterpret their advice. If a restriction is unclear, ask the client to check with their physio rather than guessing.
My client feels a new sharp pain mid-program. What do I do?
Stop the movement that provokes it and do not try to train through it or diagnose it. New sharp pain, swelling, numbness or tingling, pain that wakes them at night, or a symptom that is trending worse are all signals to refer the client to a doctor or physiotherapist. Coaching resumes once they have been assessed and cleared.
Am I allowed to give my client rehabilitation exercises?
Rehabilitation of an injury belongs to the professional treating it. If a client's physiotherapist has prescribed specific exercises, you can support them by leaving room in the program and reinforcing the plan, but you do not design a rehab protocol yourself or position general training as treatment. You coach strength and conditioning around the injury; the clinician owns the injury itself.
