Short answer
How health and fitness creators should handle YouTube comments
Sort fitness comments by the care they need, not by topic. Program logistics such as sets, reps and equipment can get an instant template. Form and technique questions get an AI draft you approve. Anything that mentions pain, injury, medication or a medical condition gets a fixed see-a-professional reply that a person approves every time.

The comments you get
What lands under health and fitness creators' videos
Illustrative examples written for this page, not quotes from real viewers.
Program logistics
How many sets and reps for the split squat? And how many days a week?
Equipment swap
I don't have a barbell, can I do this with dumbbells?
Form question
My lower back rounds at the bottom of the deadlift, what am I doing wrong?
Pain or injury
My knee clicks and hurts when I squat. Should I push through?
Medication or condition
I'm on blood pressure medication, is this workout safe for me?
Recommended rules
4 rules to start with
Each example opens in the same sentence editor you use in CommentShark. Click a highlighted part to change it; nothing here saves or posts.
1. Answer program logistics instantly
Sets, reps, splits and rest days have one answer that you control, so a keyword rule with a fixed template can run on its own once you have checked the wording. Link a program guide rather than cramming the whole program into a comment.
Rule 1: Keyword pattern + fixed reply, automatic
- When
- Keyword pattern:
\b(how many (sets|reps|days)|sets and reps|what (program|routine|split)|rest days?)\b - Then
- Reply with a fixed template: “@author The full breakdown (sets, reps and weekly split) is in my free program guide: example.com/program”
- Mode
- Runs automatically
2. Draft form answers for approval
Form questions vary too much for a template. An AI draft with a coach-voice instruction handles the variety, and approval mode lets you catch the one that drifts into diagnosis before it posts.
Rule 2: AI intent + AI reply, approval mode
- When
- AI intent: the commenter is asking about exercise form, technique, or how to perform a movement shown in the video, without mentioning pain or injury
- Then
- Reply with AI, following this instruction: “Answer the form question in two or three encouraging sentences, point to the part of the video where the movement is shown, and never diagnose pain or recommend treatment”
- Mode
- Needs approval: nothing posts until you approve it
3. Send pain and injury questions to a professional
A comment is not enough information to clear anyone for exercise. Pain is described a hundred ways, so detection needs AI intent matching, the reply is fixed, and the rule stays in approval mode permanently with email alerts on.
Rule 3: AI intent + fixed reply, approval mode
- When
- AI intent: the commenter mentions pain, an injury, a medical condition, pregnancy, or medication and asks whether they can or should do this exercise
- Then
- Reply with a fixed template: “@author With pain in the picture, I can't assess it from a comment. Please get it checked by a physio or doctor first. Once you're cleared, there are modifications for most of these movements.”
- Mode
- Needs approval: nothing posts until you approve it
4. Hold self-promotion and spam
Popular workout videos attract "check my channel" promotion and private-chat sellers. Holding keeps them off the page while you decide; nothing is deleted.
Rule 4: Keyword pattern + hold for review, automatic
- When
- Keyword pattern:
\b(check (out )?my channel|sub ?4 ?sub|subscribe to me|whats ?app|telegram)\b - Then
- Hold for review (hidden until you approve it in YouTube Studio)
- Mode
- Runs automatically
Tone and guardrails
How replies should sound, and where they stop
Tone
- Encouraging coach voice: short, specific to the movement, never judgmental.
- Point to the timestamp or your program guide instead of re-teaching the whole video in a comment.
- Keep the injury reply calm. The goal is a safe next step, not a lecture.
- Clear the approval queue before you film. The recurring questions make natural moments in the next video.
Health and safety notes
- Never diagnose, never say push through, and never prescribe exercise, diet or supplements for a specific person in a reply.
- Keep the pain and injury rule in approval mode permanently, with email alerts on.
- Treat nutrition, medication, pregnancy and eating-disorder comments like injuries: refer to a qualified professional.
- Automated replies are general information from your channel, not medical advice. Write every template that way.

Questions health and fitness creators ask
Frequently asked questions
Won't viewers dislike automated replies on a fitness channel?
Viewers dislike unanswered questions far more than fast answers. A template that accurately answers "how many sets?" with a link to the full program reads as an organized creator, especially when form questions still get personal answers. Keep the automated voice consistent with how you talk on camera.
How should fitness creators handle injury questions in YouTube comments?
Never diagnose, never say push through, and never ignore them. Detect pain and injury mentions with an AI intent rule, reply with a fixed message that sends the commenter to a physio or doctor, and keep that rule in approval mode permanently so a person reviews every reply.
How many rules does a fitness channel need?
Start with three or four: the logistics template, AI-drafted form answers, the injury guardrail and a spam hold. The free plan includes 3 rules and the Starter plan includes 10. After two weeks, the approval queue shows you which questions deserve the next rule.
What about nutrition questions in fitness comments?
Treat them like injury questions. General education is fine; individual prescriptions are not. A template that shares your general approach and links a nutrition-basics video covers most of them, and anything mentioning a medical condition, an eating disorder or medication gets the see-a-professional reply in approval mode.
Can the AI reply in my own coaching voice?
AI-generated replies follow your instruction and read your channel description and a sample of your recent replies to match how you write. Review the first drafts in approval mode, and tighten the instruction wherever you find yourself editing.
