Improve concentration with exercises

*Note: The header image is AI-generated

You're sitting at your desk, the task is actually clear, and yet your gaze lands on your phone again after two minutes. Just checking a message, then quickly answering an email, and suddenly half an hour has passed without the actual task having progressed. Sometimes we all find it hard to stay focused on one thing, especially on days with many little interruptions. Lack of discipline usually has little to do with it: attention can be trained like a muscle, with small, regular exercises instead of big resolutions.

In this article, you'll learn which three exercises help you increase your concentration, how well-researched they are, what a manageable weekly plan looks like to get started, and when it makes sense to seek medical advice.

Increasing concentration: the most effective exercises for adults, step by step

Three exercises cover the most important aspects of concentration: mindfulness breathing trains the ability to bring your thoughts back, single-tasking protects your attention from distraction, and movement gets your head going before a difficult task. For each exercise, you'll find out right after how well-researched it is.

Exercise 1: Mindfulness breathing (10 minutes)

This exercise sounds simple, and it is. The actual training happens at the moment you notice your mind wandering and bring it back. This is exactly the movement you'll need later at your desk too.

Sit up straight and set a timer for 10 minutes; 5 minutes is enough to start. Then focus your attention on your breath, for example on the rising and falling of your belly. If you wander off to your shopping list or the next meeting, briefly register it, don't get angry, and return to your breath. Repeat this until the timer rings. Wandering off twenty times means you've completed twenty repetitions.

It's best to practice in the morning before starting work, three days a week or daily, if it fits well into your routine.

And the state of research? Honestly: initial indications, no strong evidence. A systematic review of mindfulness training and cognitive abilities concludes that measurable effects probably depend on how much someone practices. A single short session is usually not enough (1). For you this means: consistency beats duration.

Box breathing as a mini-reset: If your phone has just pulled you away from a task, this breathing technique helps as a transition. Inhale for four seconds, hold for four seconds, exhale for four seconds, hold for four seconds. After four rounds, about a minute has passed, and you start the next task more consciously.

Exercise 2: Single-tasking with focus intervals

With single-tasking, you work on exactly one thing for a fixed period. This is the most direct exercise against constantly jumping back and forth between emails, chat, and actual work.

Here's how: Choose a single task and put your phone in another room, not just face down on the table. Close all browser tabs you don't need for this task. Then set a timer: Start with 10 minutes, later work your way up to the classic Pomodoro rhythm (25 minutes of work, 5 minutes break, after four rounds a longer break). If something comes to mind in between that "needs to be done quickly," write it down on a piece of paper and keep working. Two blocks per workday are enough to start.

Regarding the state of research: The Pomodoro technique dates back to the late 1980s and is an established practical method with a straightforward idea, namely dividing work into manageable blocks. However, there is no robust single study with clear numbers on this.

What is well-researched, on the other hand, is the basic principle behind it: switching tasks costs the brain time and attention. The less you switch, the more attention remains for the actual task.

Exercise 3: Movement before the most difficult task

Before you tackle the most demanding task of the day, go for a brisk walk (10 to 20 minutes). If you don't have the time, a few squats or climbing the stairs will also do. Brisk means: You get slightly out of breath, but can still talk. Two to three times a week is ideal, preferably on the days you don't meditate.

Movement is proven. A meta-analysis on acute exercise shows positive, but moderate effects of exercise on mental performance, depending on duration and intensity (2).

In a randomized study with 66 young adults, a 10-minute walk followed by 10 minutes of mindfulness meditation improved reaction time in the Stroop test significantly, while the control group did not improve (3). However, no differences were found in the other tests, and the authors themselves assess the result as preliminary.

Stroop test: A classic attention test. You see color words like "RED" printed in a different color, and you have to name the print color. This requires consciously suppressing an automatic reaction (reading the word), so exactly the kind of focus you also need against distraction.

By the way, exercises 1 and 3 can be combined well: first walk, then breathe for ten minutes, then the first focus block.

Training concentration like a muscle: your weekly plan to get started

You build concentration like strength in the gym: You start with little weight and slowly increase when it feels easy. If you force 90 minutes of focus in a row on the first day, you'll usually give up on the third. For the first two weeks, a manageable plan looks like this:

From week three on, the 10-minute blocks become two classic Pomodoro rounds of 25 minutes each. If that works reliably for a few weeks, you can expand individual blocks to Deep Work: 60 to 90 minutes of undisturbed work on a demanding task. This is the advanced stage for further development, not a must. Many stay with the Pomodoro rhythm permanently because the many little successes do them good.

A tip for the evening: Write down in one sentence when your focus was best and worst today. After a week, you'll usually recognize patterns, such as that your best block is in the morning. That's exactly where your most difficult task belongs.

What really sabotages your concentration and what helps against it

The biggest concentration killers in everyday life are smartphones, multitasking, too little sleep, and lack of breaks. For each of these, one of the exercises above is suitable:

And what about brain training apps? They mainly make you better at the games you practice in the app. There is no evidence that this transfers to your general concentration in the office or while studying. If you enjoy it, there's no reason not to. But as concentration training for everyday life, the exercises above are the more direct choice, because you train exactly what you'll need later. Sometimes your head also just feels like it's wrapped in cotton, and distraction is not the main problem at all; in this case, the articles on Causes of Brain Fog or Vitamins for Concentration and Memory can help further.

When exercises are no longer enough: the path to medical clarification

If your concentration does not improve over several weeks, although you sleep enough, take breaks, and practice regularly, a doctor's appointment is the right next step. This applies especially if the problems noticeably affect your job, your studies, or your everyday life.

Another good reason for an appointment: if something else is wrong besides concentration, for example if you feel permanently exhausted, your mood has changed, or your sleep is out of sync. It's completely understandable if you want to deal with it on your own first. But concentration depends on many things in the body, and some of them can only be clarified with an examination or a blood test.

It's best to bring your evening notes to the appointment. If you have recorded when you lack focus and what was going on at that time, your doctor can ask much more targeted questions. You can continue the exercises normally during this time.

Your first focus block begins today

Concentration is not a fixed state, but an ability you can train. The research on it is honestly varied in strength: Movement is best supported, mindfulness shows initial indications, and focus intervals are a proven practice with a straightforward idea.

Your next step is therefore very small: Choose one exercise this week, for example the 10-minute focus block with the phone in another room, and do it three days. Everything else will come later.

Some people want to supplement their routine with a dietary supplement. But the basis remains exercise, enough sleep, and movement, no capsule replaces that.

FAQ: Frequently asked questions about concentration exercises

What do I do if I break off a focus block?

Simply start a new block without judging the old one. Briefly write down what pulled you out, such as a message or a spontaneous thought. If the interruptions accumulate, the block is too long for the moment: Go back to 10 minutes.

Can I also do the exercises in an open-plan office?

Yes, with small adjustments. Box breathing can be done discreetly at your desk, for single-tasking headphones, a do-not-disturb status, and the phone in your pocket are enough. If necessary, a walk around the stairwell can replace the walk.

Which vegan nootropic is recommended for focus and concentration?

Advertisement: A vegan option is CLAV N°4 FOCUS with a plant-based capsule, green tea extract, lion's mane, and pantothenic acid, which contributes to normal mental performance. Whether a supplement makes sense for you depends on your diet and condition.

Am I too old to still train my concentration?

No. The exercises address habits, so fewer task switches, real breaks, and regular movement, and these can be built up at any age. If your concentration noticeably and persistently declines, that should also be discussed with your family doctor.

How quickly will I notice if a concentration exercise works for me?

After a walk, many people immediately notice a clearer head, with mindfulness, it takes longer. Research indicates that regular practice counts there, not a single session. Therefore, give each exercise at least two weeks before you evaluate it.
