How to stay consistent with exercise when work is demanding
By Anubhav··5 min read
To stay consistent with exercise when work is demanding, plan for the week you will actually have. Set a floor and a target for each week, the least you will always do and what a calmer week allows, keep a short version of every session, and book sessions in your calendar like meetings. When the week changes, the plan changes with it.
In our experience, the people who stay consistent with exercise through busy years have a plan that bends with their week. With a demanding job, that week moves around: a deadline shifts, a trip comes up, a dinner runs late. Below is how we build plans like that for clients whose weeks change from one to the next, and how you can do the same.
What is the least you can do and still make progress?
Less than you might expect. Harvard Health’s guide to starting strength training notes that two full body sessions a week can produce measurable changes in strength. The US Physical Activity Guidelines say plainly that some activity is better than none, and since 2018 they count activity of any length towards the weekly total.
That is why every plan we write has a floor and a target. The floor is the least you will always do, even in your busiest week. The target is what a calmer week allows. The numbers are different for everyone, because they depend on your goals, your training history and what your weeks really look like. For one person the floor is two sessions and the target four. For another it is one session and a long walk. A week that only reaches the floor is still a good week, and it keeps everything you have built moving forward. The NHS puts it simply: exercise just once or twice a week can reduce the risk of heart disease or stroke. And a large UK study found a similar benefit for heart health whether people spread their activity across the week or fitted it into one or two days.
How do you find time when every week looks different?
Pick your slots at the start of each week, before the week picks them for you. Ten minutes on a Sunday evening with your calendar is enough. Put the sessions in as appointments, with a time and a place, and treat moving one the way you would move a client call: you find it a new slot.
It also helps to decide in advance what you will do when a slot disappears. Psychologists call these if-then plans, and reviews of trials find that people who make specific plans, including plans for when things go wrong, tend to do more physical activity. Something as simple as “if the 7am session goes, I train at lunch” takes the decision off the day itself.
The slots that survive busy weeks tend to be the ones nobody else wants: before the house wakes up, a lunch hour, or after the children are in bed. Early sessions have one extra advantage for people with unpredictable days, because nothing has gone wrong yet.
Have a short version of every session
In our experience, the change that keeps people training through busy months is a shorter version of every workout. When you only have 20 minutes, you do the 20 minute version. You never have to skip because the full session no longer fits.
| Time you have | What you do |
|---|---|
| 20 minutes | A short warm up, then the two or three main lifts for the day, two sets each |
| 35 minutes | The full warm up, the main lifts, and one or two accessory exercises |
| 50 minutes | The whole session as written, including conditioning at the end |
The shorter versions keep the most important work and drop the rest, so the main lifts still happen every week.
What do you do when a week falls apart?
Carry on from where you were. Repeat the week you were on, and resist the urge to make up the missed sessions by cramming them into the weekend. That usually leaves you sore for the next week as well.
A missed week feels bigger than it is. In a well-known University College London study of how habits form, missing the occasional day did not seriously set the habit back. Missing often did, so what matters is getting back to the next session. The floor makes that easier, because it is set at a level you can always reach.
A quick check on Wednesday helps too. Count what is done, look at what is left, and move or shorten the remaining sessions so the floor still happens.
How do you keep training when you travel?
Plan the travel version before you go. Most hotel gyms have dumbbells, a bench and a treadmill, and that covers a squat, a hinge, a push and a pull. If there is no gym at all, the same four movements work with your bodyweight in a hotel room. Treat a travel week as a floor week and you will come home with nothing to catch up on.
After a long-haul flight, sports scientists advise training at low to moderate intensity on arrival, so the first day is a good one for a walk and some easy movement. The same goes for a short night. A review of 69 studies found performance dipped after six hours of sleep or less, mostly in sessions later in the day, so a shorter, easier session, earlier if you can, keeps the week going.
How long until it feels automatic?
Longer than a few weeks, so it is worth knowing in advance. In the same research, people took a median of 66 days for a new daily behaviour to feel automatic, and the range ran from 18 to 254 days, as a 2024 review summarises. Simpler habits formed faster than more involved ones, and a workout is at the involved end. In practice, the first two months are the part that takes effort. After that, training tends to become part of the week in the same way the commute is.
Where a coach fits, if you want one
Everything above works on your own. Where a coach helps most with a demanding job is setting your floor and target in the first place, then the week to week rewriting: moving sessions when the diary changes, deciding which work to keep when time is short, and noticing when you have gone quiet for ten days. That is most of what we do.
