Stop the set, say it out loud, and describe it: where, which movement, and whether it is sharp or dull. Then let the coach decide what happens next, which is usually a swap to a pattern that does not hurt or a lower load, not the end of your session. Pushing through is the wrong instinct because pain during a rep is information arriving faster than you can reason about it; quitting the session is usually wrong too, because most mid-session pain is a movement that needs changing, not a body that needs the day off. Anything sharp, anything with swelling, numbness or a change in how you walk, and anything still there the next morning goes to a physiotherapist or physician. A coach's job is to send you there, not to guess.
This is general information for the moment itself. Soreness that arrives a day later, and knees that complain specifically when you squat, have their own pages.
The protocol, in order
- Stop the set. Rack the bar or set the dumbbell down under control; do not finish the rep to prove a point.
- Say it out loud. A coach cannot see pain, and in a group of eight they may be at the far rack. One word brings them over.
- Describe it in three parts: where it is; whether it is sharp, dull, burning or pinching; and whether it came on the way down or the way up.
- Let the coach swap or drop. Their options are a lower load, a shorter range, a different pattern, or a different tool, such as a cable instead of a dumbbell.
- Finish with what does not hurt. The rest of the session still counts.
- Note it on your sheet before you leave, so the next session is written around it rather than repeating it.
Effort or pain: the difference in a table
Push through it is a reasonable cue for the burn of a hard set and a dangerous one for pain. Coaches tell them apart by pattern, and you can too.
| Discomfort that is effort | Pain that is a signal |
|---|---|
| Both sides, builds with the reps | One side, arrives suddenly |
| Fades within a minute of stopping | Still there after the set |
| In the belly of the muscle | In a joint, a tendon, or near bone |
| The same on every rep | Worse at one specific angle |
| Dull soreness tomorrow at most | Worse tomorrow, or wakes you |
Anything in the right-hand column ends the set. Anything in the left is the work.
Why quitting the session is usually wrong too
Leaving after a tweak loses the session, and the habit takes the hit with it. A swap keeps the day. The usual moves: a knee that pinches at depth becomes a hinge day; a shoulder that catches on an overhead press becomes a floor press or a row; a low back that complains on the deadlift becomes a glute bridge and carries. In a coached group the swap list for common complaints is written before you arrive, which is why a coach can change your station in ten seconds without stopping the room.
The exception is anything from the right-hand column that does not settle within a few minutes of stopping. Then the session ends, and the next stop is a clinician.
The same-day and next-morning checks
These are the questions a coach asks the next time they see you, and you can ask them yourself.
- Same day: did it settle within an hour or two? Can you walk, climb stairs, sit and stand normally? Any swelling or visible change?
- Next morning: is it stiffness that eases as you move, or pain that is the same or worse? Any numbness, tingling, or a joint that feels like it might give way? Did it wake you?
Stiffness that eases is usually a tissue that worked and is fine. Anything else on that list is a physiotherapist or physician question, promptly, and the coach will say so. Trainer or physiotherapist lays out who does what in BC.
What the coach does afterward
Writes it in your record. Rewrites the next session before you arrive, so the pattern that hurt is swapped or lightened rather than tested. Asks how it was at the start of that session. Refers you if it repeats, and welcomes anything a physiotherapist sends back, because a clinician's notes make a better program. If you arrive at a small group session with a known complaint, say it at the briefing; the room is built to absorb one person's swap.
Four things not to do
- Do not test it repeatedly to see whether it still hurts. It does, and each test costs tissue.
- Do not go quiet and grind through the next station. Silence is the one thing a coach cannot work with.
- Do not decide what it is from a phone in the change area. Describing is your job; diagnosing is a clinician's.
- Do not skip the next session out of caution without asking. The swapped version is usually the right medicine.
Training when sore covers the separate question of ordinary next-day soreness and when it stops being ordinary.
Common questions
Will I be holding up the rest of the group if I stop?
No. Stations are individual, so your stopping changes nothing for the other seven. The coach swaps your movement and the room carries on.
What if it only hurts a little?
Say so anyway. A little is a description the coach can work with, and it is far easier to adjust a set than to unpick a week. Minor discomfort that sits in the left-hand column of the table above is usually fine to keep working around.
Should I stretch the spot that hurt?
Not hard, and not in the moment. Gentle movement through a comfortable range is fine; stretching aggressively into the painful angle is a common way to make a small thing bigger.
Can I come back the next day?
If the next-morning checks are clear, yes, and the session will be written around it. If any of them are not, book the clinician first and tell the studio what they said.
Will the coach think I am making excuses?
No. Reporting pain early is exactly what coaches ask for. The client who says nothing is the one who worries a coach.
