What to do with the client who says they have no time
"I couldn't this week, everything piled up." It is the most repeated sentence in the job and the worst answered, because the instinctive reply — insisting on how important training is — addresses an objection the client never made. The sentence rarely describes a full calendar. It describes an order of priorities, and that is worked on differently.
Key terms
- Perceived barrier
- What a person identifies as the obstacle keeping them from training. It is a self-assessment, so it reflects both the real constraint and how they explain it to themselves.
- Minimum effective dose
- The lowest volume that still produces a measurable effect. It works as a negotiable floor when availability collapses.
- J-shaped curve
- A dose-response relationship where benefit rises quickly at first and then flattens, so the first stretch delivers nearly all of the effect.
- Minimum session
- The shortest version of the programme, written in advance, that the client runs in the weeks when the full version does not fit.
Lack of time tops the ranking of exercise barriers in practically every population that has been studied, and it is also the barrier most readily accepted without examination. When a client states it, the conversation usually ends there, because questioning it feels like questioning them.
The literature offers a less awkward way out. What people report when they say they have no time is not always a scheduling conflict, and that distinction determines which of two very different interventions applies.
What the barrier measures when it is measured properly
Cavallini and colleagues surveyed 582 adults aged 18 to 64 across two unrelated populations — 277 in southern Ontario and 305 in South Carolina — and published the results in the Journal of Physical Activity Research in 2020. Lack of time came out as the consistent barrier in both places and for both genders.
The interesting figure sits one level down. When the individual statements were broken out, the most endorsed one in both populations was not about scheduling but about priority: "there are so many other things I have to do, it is easy to make excuses rather than exercise".
That does not make the client a liar. It makes the sentence a summary: under "I have no time" live both a real availability problem and a hierarchy problem, and those get solved differently.
The diagnosis is one short concrete question. How many thirty-minute blocks did they have last week, and what filled each one. The answer separates the two cases in a minute: someone working twelve-hour rotating shifts is describing constraints, and someone who had four free evenings is describing something else.
- Cavallini et al. (2020): 582 adults across two independent populations.
- Lack of time was the consistent barrier in both.
- The most endorsed statement was about priority, not about the calendar.
The floor is far lower than the client thinks
A good part of the problem is expectation. Someone who assumes training means an hour, four times a week, and who only has two thirty-minute gaps, concludes it is not enough and never starts. The reasoning is sound and the premise is wrong.
Momma and colleagues published a systematic review of 16 cohort studies on muscle-strengthening activities in the British Journal of Sports Medicine in 2022. Between 30 and 60 minutes a week was associated with a 10 to 20% lower risk of all-cause mortality, cardiovascular disease, diabetes and cancer, independently of aerobic exercise. The relationship traces a J-shaped curve, with no conclusive evidence of further benefit beyond an hour a week.
For strength adaptations the floor is low too. A narrative review published in Sports Medicine under the heading of minimalist training concludes that, for beginners and at least through the first 8 to 12 weeks, one weekly session with fewer than three sets per exercise, 6 to 15 reps and multi-joint movements is enough for substantial improvement. The authors are clear that heavier loads perform better, and even so the floor sits well below what usually gets prescribed.
That number is what should go back to the client, with the caveat that it is a floor and not a target. Thirty minutes a week turns the conversation from "I can't sustain the programme" into "I can sustain this version".
- Momma et al. (2022): 30 to 60 minutes a week, 10-20% lower risk across mortality and major diseases.
- The curve is J-shaped: the first stretch delivers nearly all the benefit.
- Behm et al.: one weekly session is enough for substantial gains in beginners.
Redesigning the programme for the time that exists
The minimum session gets written before it is needed, with a name of its own and specific exercises. Improvising it on the day the client says they cannot make it always produces the same outcome: the session does not happen.
Three decisions carry almost all of the time saving. The first is dropping isolation work: multi-joint movements cover more muscle per minute and are what the minimalist literature itself recommends. The second is pairing exercises that do not compete with each other, so one's rest is the other's work. The third is removing every dependency on specific equipment, because one occupied machine turns a twenty-five-minute session into a forty-minute one.
It is also worth setting the frequency floor at two rather than three. A client who drops from three sessions to two keeps the habit; one who drops from three to zero loses it, and rebuilding it costs far more than holding it at half speed.
The other front is the friction of starting. Having the routine loaded and available the moment the client walks into the gym removes the stretch where sessions most often collapse. That is the underlying argument of the 165 hours you don't coach: what decides the result happens when the trainer is not there, and only what was written down gets that far. The client app exists for exactly that.
- Write the minimum session before you need it, with specific exercises.
- Multi-joint work, non-competing pairs, zero dependency on one machine.
- Frequency floor at two sessions: holding the habit beats holding the volume.
When the problem is priority rather than schedule
The other case calls for a different intervention, and neither of the two usual versions works: not the motivational speech, and not quietly shrinking the programme.
What tends to move things is making the cost of the decision visible with data that already exists. A client who sees that they held four weeks straight, then missed two, and that their loads are back where they were in March, has a different conversation with the subject. The log does that work better than any argument.
Then the commitment comes down to something that competes with nothing. Two twenty-minute sessions, on fixed days, explicitly agreed as the floor for the period. A small commitment that gets met rebuilds the relationship with the programme; a large one that gets missed erodes it every week.
And contact shortens in the same direction. One concrete question about next week, on the day it belongs, does more than a long message on Sunday. Chat with the client's history alongside it is what makes doing that across a whole roster workable.
- Show the history instead of arguing: the log makes the case better.
- Lower the commitment until missing it becomes impossible.
- Short, concrete contact, on the day it belongs.
The statement most endorsed by those 582 respondents did not describe a full calendar: it described how easy it is to make excuses.
What to take away
"I have no time" summarises two different problems, and they are worth separating before answering. One question about how last week got filled is enough to know which one is in front of you.
If it is scheduling, the work is design: a minimum session written in advance, multi-joint, free of equipment dependencies, with the frequency floor at two. And it is worth telling the client where that floor actually sits, because most of the health benefit already shows up between 30 and 60 minutes a week.
If it is priority, the work is evidence and commitment size: show them their own history and shrink the ask to something they can meet. In both cases, what holds the result together is the programme being ready and to hand when the free stretch appears.
