A client check-in is a recurring form a client completes on a set schedule — usually weekly — reporting their body metrics, photos, training and nutrition adherence, sleep, energy and anything that got in the way. It is the fixed point where you review the week and decide what changes.
The name is used loosely. Some coaches mean a form, some mean a video call, some mean a long message on a Sunday night. All three are check-ins in the sense that matters: a scheduled moment where the client reports and you respond. The difference is how much of it you can compare to last week.
Why the check-in exists
In person you get the information for free. You see the client twice a week, you watch the set, you hear that they slept badly before they tell you. Coaching online strips all of that out, and the check-in is what you put in its place — a structured report on the seven days you didn't see.
That is why it is a form rather than a conversation. A conversation gives you this week's story. A form gives you this week's numbers next to the previous six, which is the only way to tell a plateau from a bad weigh-in day. This is the mechanism that makes asynchronous coaching work at all: you are not reacting in real time, so you need a reliable moment where the information arrives.
A weekly form is also a deadline. Clients who know they are reporting their adherence on Sunday behave differently on Wednesday, so the check-in drives compliance as much as it measures it.
What goes in a weekly check-in
Four kinds of data plus one open question, and each answers something different. A check-in that collects only one of them is why coaches end up asking three follow-ups before they can write a reply.
| What you collect | Example | What it tells you |
|---|---|---|
| Objective metrics | Weight, waist and hip measurements, average daily steps | Whether the plan is working. Trend over three or four weeks, never a single reading |
| Subjective ratings | Sleep, energy, hunger, stress, soreness — rated on a consistent scale | Whether it is sustainable. These move before the scale does and are your early warning |
| Adherence | Sessions completed out of sessions programmed, days on target with nutrition | Whether you are adjusting a plan or a plan that was never followed |
| Progress photos | Front, side and back, same lighting, same time of day | What the scale misses. Recomposition can run for months with no weight change |
| Open comment | "What got in the way this week?" | The context — a work trip, a sick child, an injury — that explains the numbers |
Read adherence before metrics. If a client hit four of six sessions and ate at maintenance twice, there is nothing to adjust and the conversation is about the barrier, not the calorie target. Coaches waste a lot of time redesigning programs that were never run.
Keep it to something a client can finish in five minutes. Ten thoughtful answers beat thirty rushed ones, and every question you add is a question someone will eventually skip. There is a full question-by-question build in the client check-in template.
Where check-ins actually happen
Most coaches start with a spreadsheet or a Google Form, and it works until roughly client fifteen. Then the failure modes arrive: chasing the people who didn't submit, photos scattered across a camera roll, and no way to see this week beside last week.
Purpose-built check-in forms fix the mechanics rather than the coaching. You build the form once, put it on a weekly or monthly schedule, and assigned clients get reminded in their own timezone. Body-metric and progress-photo answers land on the client's profile instead of in a message thread, and you can put two submissions side by side to see what actually moved.
What you do with it
A check-in nobody reads is worse than no check-in, because the client filled it in and got silence back. Submissions should sit in a queue until you have responded to them, and your reply should name the change and the reason for it: what you saw, what you are adjusting, what you want next week.
Response speed matters more than response length. A three-line reply within a day beats a page-long analysis on Thursday, because the client is still in the week you are talking about. Reviewing on a fixed day — Monday morning for Sunday check-ins — is faster than handling them as they land.
The full process, including how to batch reviews and what to write back, is in how to run client check-ins.
