The short answer
The session still runs: the injured partner trains a scaled version of the same movement patterns while the other trains normally, and the coach adjusts range, load and tempo rather than dropping the exercise.
- See a doctor or physio first if the injury is recent, painful at rest or undiagnosed, because a coach works within clearance and does not diagnose.
- Couples rates on our roster start from S$40 per person.
- Some injuries justify a few weeks of 1-to-1 first.

Key facts
- The session runs in two versions of the same hour, rather than being cancelled
- See a physio or doctor first for pain at rest, night pain, numbness or weakness
- The NHS describes the first 48 to 72 hours after a sprain or strain as the settling window
- 2 coached sessions a week still meets the ACSM target for the uninjured partner
Can you still train together if one of you is injured?
Yes, in most cases, and it is more common than couples expect. The coach runs the same session in two versions: the injured partner works around the area while the other trains normally. An ankle does not stop you pressing, rowing or carrying, and a shoulder does not stop you squatting.
In our own coaching experience the pairs who cancel are the ones who assume the whole plan is off. It rarely is. Tell the coach before the session rather than during it, so the change is planned rather than improvised in front of you.
When do you need a physio before a coach?
Before training, if the injury is recent, undiagnosed, or behaving badly. See a doctor or physiotherapist first for pain at rest, pain that wakes you at night, numbness, pins and needles, weakness in a limb, a joint that gives way, or anything that has not improved over a couple of weeks.
The NHS guidance on sprains and strains describes the first 48 to 72 hours as the settling period, and something that is still severe well past that is a clinical question rather than a coaching one. A coach works within whatever your clinician allows. We do not diagnose, and this page is general information rather than medical advice.
What actually changes in the session?
Range, load and tempo change before the exercise does. A coach's first move is to shorten the range or lighten the load, not to delete the movement, because the pattern is usually worth keeping even when the full version is not available.
| Injured area | What that partner does | What the other partner does |
|---|---|---|
| Shoulder | Lower body, carries, core, pain-free pulling | Full upper-body pressing and pulling |
| Knee | Upper body, hip hinge within range, supported single leg | Squats, lunges, step-ups |
| Lower back | Supported positions, breathing work, short-range hinge | Loaded hinge and squat patterns |
| Ankle | Seated and supported work, upper body, hip strength | Standing and single-leg work |
| Wrist | Straps or a neutral grip, lower body unaffected | Normal grip work |
What about an old injury that never quite healed?
That is the more common case, and it is usually trainable. An ankle sprained years ago that still feels unreliable on uneven ground is a balance and strength problem rather than an acute injury, and it responds well to calf, foot and single-leg work built up slowly.
Tell the coach the history anyway, including what it stops you doing rather than only what it is called. In our own coaching experience "I can't trust it going down stairs" tells a coach more than a diagnosis from 2018 does. Related reading is on knee injury training, shoulder injury training and injury rehab.

When should the injured partner train alone for a while?
When the injury needs most of the coach's attention. A shared hour splits a coach's eyes, and there are cases where the injured partner needs all of them for a few weeks before rejoining.
- 01Post-surgicalA rebuilt knee or shoulder inside its rehab window needs a dedicated hour, usually alongside a physio.
- 02Recent and painfulAnything still sharp needs assessment and close supervision before it belongs in a shared session.
- 03Fear of the movementA partner who has stopped trusting a joint often needs privacy to work through it, not an audience.
- 04Very different sessionsWhen the two plans no longer overlap at all, you are paying couples rates for two solo sessions running in parallel.
This is a case where the answer that costs less is usually the right one and is also the one we give. Splitting for four weeks then rejoining is normal.
Will the uninjured partner fall behind?
No, if the coach programmes it properly. The uninjured partner trains their normal plan. The adjustment is on the other side of the room. The American College of Sports Medicine's activity guidance is met by the same two sessions a week either way, and a modified partner does not reduce your load.
Where couples do lose ground is attendance, not programming. If the injured partner cancels the session outright, both of you miss it, so agree early that the session runs whoever is fit. Confirm what the coach charges when only one of you attends, because that rule varies and is covered in sharing a package.
Where should you train while one of you is injured?
At home or in your condo gym, because getting there is often the part that hurts. An injured knee that copes with a session still has to get down an HDB block where the lift stops on alternate floors, and a coach who comes to you removes a flight of stairs from each end of the hour.
- 01HDB flatEnough for the seated, supported and band work most injuries need, and no stairs or MRT to negotiate first.
- 02Condo gymMachines let an injured partner load a pattern safely while the other uses free weights. Check the MCST rules for external trainers before booking.
- 03OutdoorsWorkable for an upper-body injury, poor for an ankle. Uneven park connector surfaces and Singapore's heat both add risk to a joint you are already protecting.
- 04Public gymNot for coached sessions, because ActiveSG's rules do not allow personal training without its prior written approval. Use it on your own between sessions, and remember a busy floor is the worst place to protect a shoulder.
One Singapore-specific note on getting seen. A polyclinic referral to physiotherapy can take time, and in our own coaching experience couples often start training around an injury while that appointment is still pending. That is reasonable for an old niggle and not reasonable for something acute: if it is new, sharp or undiagnosed, the training waits for the clinician rather than the other way round.
What should stop a session immediately?
Sharp pain, a joint giving way, numbness or pins and needles, sudden weakness, or pain that gets worse set by set rather than easing as you warm up. Stop, and get it looked at rather than finishing the hour.
Back pain deserves its own line here, because it is the injury couples most often try to train through. HealthHub's guidance on low back pain and SingHealth's material on slipped disc both describe the same warning signs: pain radiating down a leg, numbness or weakness in the foot, and any loss of bladder or bowel control, which is an emergency rather than a training question.
A coach who is told "my back is a bit tight" will programme around it. A coach who is told about numbness should be sending you to a doctor.
Chest pain, unusual breathlessness, dizziness or a severe headache means stop and seek medical attention, injury or not. A coach modifies training. A coach does not diagnose, clear you, or manage a condition. If in doubt, the session can wait. Terms like range of motion and RPE are defined in the fitness glossary.

Injured partner questions.
Can we keep training as a couple if one of us is injured?
Usually yes. The coach runs two versions of the same session: the injured partner works around the area while the other trains normally. Tell the coach before the session, not during it, and see a physio first if the injury is recent or undiagnosed.
When should an injured partner see a physio before a personal trainer?
For pain at rest, pain that wakes you at night, numbness, weakness, a joint that gives way, or anything not improving after a couple of weeks. The NHS treats the first 48 to 72 hours after a sprain as the settling window. Still-severe pain past that is a clinical question.
Will the uninjured partner get a worse session?
No, if the coach programmes it properly. Your plan does not change. The modification sits on the other side of the room, where the coach adjusts range, load and tempo for the injured partner rather than dropping the exercise. Couples lose progress through cancelled sessions rather than through a partner training a scaled version.
What happens if my injured partner cannot attend at all?
Agree the rule before you pay. Most coaches either run the hour 1-to-1 at the solo rate or reschedule with 24 hours' notice. It varies by coach, and it is the clause couples most often wish they had confirmed in writing.
Can a personal trainer treat an injury?
No. A coach trains within whatever your doctor or physiotherapist allows, and does not diagnose, treat or issue clearance. Good coaches work alongside a physio and will ask what you have been told to avoid. Anything sharp or new goes back to the clinician.
Should we pause training until the injury heals?
Rarely the best option. Stopping entirely costs the uninjured partner months and usually ends the habit for both. Training around an injury, within clearance, keeps the appointment alive and often helps the injured side recover better than rest alone. See a doctor or physio first if the injury is recent, painful at rest or undiagnosed.
