Are 20-Minute Workouts Effective?
Are 20-minute workouts effective? It’s a fair question, particularly when we’re often made to feel that a “proper” workout needs to last 45 minutes or even an hour.
We’ve probably all done it. You look at the clock, realise you’ve only got 20 minutes before you need to get on with something else and decide there isn’t really enough time to exercise.
I’ll do it tomorrow.
The problem is that tomorrow can be just as busy.
But that’s a lot of potentially useful exercise we’re writing off. If you exercised for 20 minutes four times a week, that’s 80 minutes of purposeful movement you might otherwise have missed. Add walking and the other activity you do throughout the week, and suddenly those shorter workouts don’t seem quite so insignificant.
Of course, 20 minutes isn’t a magic number. What you do during that time, how regularly you exercise and how active you are during the rest of your week all matter.
However, if the choice is between a 20-minute workout today and waiting for that elusive free hour to appear in your diary, those 20 minutes can be very well spent.
Stop Thinking of Exercise as All or Nothing
I think this is where many of us make exercise harder than it needs to be.
If your idea of a “proper workout” involves changing, travelling to a gym, exercising for an hour, showering and travelling home again, you might need a fairly substantial gap in your diary before exercise even feels possible.
At home, that changes.
If you’ve got 20 minutes, you can actually use those 20 minutes.
You don’t need to spend ten minutes travelling anywhere or wait for a piece of equipment to become available. You can choose a workout, make a little space and start moving.
And perhaps more importantly, you haven’t failed if you don’t have an hour.
Twenty minutes of movement is still twenty minutes more than you would have done if you’d decided there wasn’t enough time.
What Can You Actually Achieve in 20 Minutes?
Quite a lot, depending on the workout.
You could complete a full-body strength session using bodyweight or resistance. You could raise your heart rate with an aerobics or dance workout. You could work on your core with Pilates or spend the time improving mobility and flexibility.
You could also simply go for a brisk walk.
The important thing is having some purpose behind the session.
A well-structured 20-minute workout can use your time efficiently rather than feeling like a shortened version of something that was supposed to last an hour.
That’s one reason so many InstructorLive programmes use sessions of around 20 minutes. We know that fitting exercise into real life isn’t always easy.
Consistency Can Matter More Than One Big Workout
Imagine two different approaches.
You plan to exercise for an hour three times this week, but life gets busy and you only manage one session.
Alternatively, you plan four 20-minute workouts and actually complete all four.
The longer individual workout isn’t automatically the better routine.
The routine you can realistically repeat is usually far more useful than an ambitious plan you struggle to maintain.
This is why I’m increasingly interested in making exercise manageable.
If 20 minutes feels achievable on a busy Tuesday, you’re much more likely to do it. Once you’ve finished, you might even decide you have another ten minutes available.
But you don’t have to.
You’ve already done what you planned.
You Still Need Variety
Short workouts don’t mean doing the same thing every day.
In fact, a 20-minute format makes it relatively easy to create variety across your week.
You might do strength on Monday, Pilates on Wednesday, cardio on Friday and go for a longer walk at the weekend.
Alternatively, your goals might mean putting more emphasis on strength while using walking or another activity for your cardiovascular exercise.
There’s no single perfect weekly routine for everyone. Your fitness level, experience, health, goals and available time all matter.
The important thing is not to judge the value of a workout purely by the number on the clock.
Twenty Minutes Doesn’t Mean Twenty Minutes at Maximum Effort
This is worth saying because shorter workouts can sometimes be marketed as though every second needs to be incredibly intense.
It doesn’t.
You shouldn’t need to collapse on the floor at the end for a workout to have been worthwhile.
A 20-minute strength workout can involve slow, controlled movements. Pilates might focus on control, stability and technique. A lower-impact session can still get your body moving without involving jumping or high-intensity exercise.
Intensity is simply one variable.
The right level should depend on you and the type of exercise you’re doing.
Try 20-Minute Toning
If you’re wondering what you can actually achieve in a shorter session, 20-Minute Toning is a great place to start.
The programme is designed around short, manageable workouts that you can fit more easily into your day while still giving your body a focused session.
It’s particularly useful on those days when the biggest barrier to exercising isn’t necessarily motivation, but simply finding the time.
And if toning isn’t what you’re looking for, you’ll find plenty of other shorter sessions across InstructorLive, including strength, Pilates, cardio and lower-impact options.
Don’t Forget About the Rest of Your Day
A 20-minute workout also doesn’t have to represent all of your movement for the day.
You might complete a workout in the morning and then walk to the shops later. Perhaps you take the stairs, walk the dog or spend some time in the garden.
As we’ve talked about previously, everyday movement counts too.
Your fitness routine doesn’t have to exist inside one neat block of time.
A shorter workout can simply be one part of an active day.
What If You Have More Time?
Use it!
I’m certainly not suggesting everyone should stop doing longer workouts.
There are days when I enjoy having more time to train, and longer sessions can give you opportunities that simply aren’t possible in 20 minutes.
The point is that it doesn’t have to be one or the other.
Some days you might have an hour. On another, you might have twenty minutes.
Rather than deciding the shorter session isn’t worth doing, adapt.
Fitness has to work in the life you actually have, not the imaginary week where nothing goes wrong and you’ve somehow got unlimited free time.
The Takeaway
I’ve gone from periods of my life when movement filled almost every waking hour to days when I genuinely have to make an effort to step away from my computer.
That’s changed the way I think about exercise.
I don’t judge a workout by whether it lasted an hour anymore.
If I’ve got 20 minutes and I use them well, that’s worthwhile. If I’ve got longer, brilliant. And if one busy day all I manage is a walk, that’s still movement.
So the next time you find yourself thinking, I’ve only got 20 minutes, there’s no point, try turning that thought around.
You’ve got 20 minutes. What could you do with them?
