How long should a check-in reply be?

Four short paragraphs, under 150 words. Long enough to show you read the check-in, short enough to read on a phone.

What if the client reported pain or an injury?

Acknowledge it and say you will follow up personally. A reply never gives medical or injury advice; trainers screen and refer.

Should every reply include a change?

No. If the week went to plan, the change is to keep the plan. One change at a time is what makes it stick.

How does Fenlio write a check-in reply?

From that client's own record: their check-ins, messages, the facts they told you and the numbers they reported. A figure with no source in their own words is flagged, and the reply waits in your Inbox.

Check-in reply template for fitness coaches

A check-in reply is the message a coach sends back after a client's weekly check-in.

What goes in it

It names one specific win, says what the week actually shows using only the figures the client reported, offers one change for the coming week with its reason, and closes with one small ask. Keep it to four short paragraphs, send it the same day, and hand any pain or illness to a personal follow-up.

Under 150 words in total, as four short paragraphs.

1
Opening
The client's first name and one specific win from this check-in, in their own words where possible. Showing up counts even when the numbers did not move.
2
What the week shows
Two or three sentences on what this check-in actually shows. Only figures the client reported; never a number they did not give.
3
One change
One adjustment for the coming week and why, drawn from your program, nutrition notes or method. If your notes support no change, say to keep the plan. If the client raised pain, an injury or illness, say you will follow up personally instead.
4
One ask
One small, specific thing to do or answer before the next check-in, offered as their choice.

When to send it

The same day a client sends their weekly check-in.
After a fortnightly or daily check-in, kept shorter for daily ones.
When a client sends a progress update between check-ins and expects an answer.

Common mistakes

A list of corrections, which reads as homework and gets skimmed.
Quoting a number the client never reported.
Three changes at once, so none of them sticks.
Giving injury or medical advice in a reply instead of following up personally.

Why it works

Coaching practitioners converge on one shape for a check-in reply: name one specific win, read what the week actually shows, give one adjustment, and close with one ask. A wall of corrections reads as homework and gets skimmed.
Coachway, How to write client check-in messages
Validation first, the adjustment second, encouragement last: the order coaching practitioners recommend for a check-in reply.
HubFit, The ultimate guide to online coaching check-ins
Focus a client on one practice at a time, name any positive progress, and ask how confident they are that they can do the next step.
Precision Nutrition, PN coaching revealed
Across 184 data sets, practitioner support for a client's autonomy went with more autonomous motivation and better health outcomes, so a change is offered with its reason rather than ordered.
Ng et al. 2012, Self-determination theory applied to health contexts (meta-analysis)
Trainers screen and refer; physicians clear and diagnose. A check-in reply never gives medical or injury advice, and pain or illness is handed to the coach personally.

Let Fen write it

1
Bring the client's record
Their intake, check-ins and messages, pasted, dropped or imported into that client's record.
2
It can't make up a number
Every weight, date and figure Fen writes is checked against the client's own words, and a load or macro target is computed from your rules. One with no source is flagged, never guessed.
3
You decide what goes out
At default settings nothing reaches a client until you press. Email replies go out from your own Gmail when you press Approve and send.
