The 5-Hour Week: How you can accomplish in 45 minutes as much as others do in 3 hours

A 25-hour workweek with full pay? Sounds like an unrealistic dream. Entrepreneur Lasse Rheingans showed how it can work: at his digital agency he introduced the five-hour day – with surprising results. His employees became more productive, more creative, and more satisfied [citation:1][citation:2]. The message: presence is not the same as performance. The key lies in how we work – not in how long. We show you how to maximize your productivity with the 45-minute method.

1. The 5-Hour Revolution – What’s behind it?

Lasse Rheingans, CEO of Rheingans Digital Enabler in Bielefeld, made headlines in 2018: he introduced the 25-hour workweek with full pay [citation:1][citation:2]. The experiment was not a given success – but it worked. Employees accomplished in five hours what they had previously done in eight hours [citation:1][citation:10].

Rheingans' core message: "The equation presence time = performance is deeply ingrained in our minds. Which wouldn't be such a problem if it still held true today" [citation:1][citation:2]. His approach is holistic: fewer meetings, no interruptions, no multitasking – instead focused, productive work phases [citation:13].

Rheingans' conclusion after years of practice: "The five-hour day is not enough." It's about a fundamental reorientation of work culture [citation:1][citation:10].

2. The science behind 45-minute focus blocks

Why does this work? The answer comes from ultradian rhythm research. Our brain is not built for hours-long continuous focus [citation:7][citation:8].

Neuroscience shows that concentration follows biological cycles of about 80 to 120 minutes. Within these cycles there are peaks of attention – and phases when performance declines [citation:8]. The first 45 minutes of a cycle are particularly valuable, because the brain offers here [citation:7].

The 45-minute method leverages this rhythm: you work in short, intense blocks and then take a deliberate break. The brain can regenerate, and the next peak performance becomes possible [citation:7].

3. How to implement the method

a) The 45-minute block

Choose a single, meaningful task – not a to-do list, not multitasking. Set a timer for 45 minutes and work without interruption [citation:4][citation:7]. No emails, no social media, no phone – just you and the task [citation:7].

b) The 15-minute break

When the timer rings: Stop! Even if you are in the middle of something. Use the 15 minutes intentionally: get up, drink water, stretch, step outside briefly [citation:7]. The break is not a luxury but the prerequisite for the next top performance [citation:8].

c) The Pomodoro variant

The famous Pomodoro technique works with 25 minutes focus + 5 minutes break – also highly effective against procrastination [citation:11]. For longer, more complex tasks, however, 45 minutes are often better suited [citation:7].

4. The biggest pitfalls – and how to avoid them

The 5-hour revolution doesn’t fail because of the idea but because of implementation. Rheingans names the biggest hurdles [citation:1][citation:2]:

• Customer availability: Anyone who always has to respond immediately will never work focused. Solution: set clear communication times.
• The "quick chat" with colleagues: Exchange is important – but not during focus time. Solution: fixed times for team communication.
• The inner brake: Many cannot believe that short work can truly be productive. Solution: try it first, then judge [citation:2].

5. Conclusion: Less is more – if you do it right

The 5-hour revolution shows: productivity is not a question of working hours but of the way you work. The 45-minute method is a practical way to break out of the trap of "presence culture" [citation:1][citation:2].

Of course: not every profession can be compressed into five hours. But everyone can benefit from more focus and intentional breaks. Try it – you will be surprised how much you can achieve in 45 minutes [citation:7][citation:8].

FAQ: Frequently asked questions about the 5-hour week

Does the 5-hour week work in every profession?

The method is especially suitable for knowledge-intensive work. In professions with high customer contact or in care, other solutions are needed [citation:13]. The core – focus phases and intentional breaks – is, however, universally applicable.

How do I find out which block length is ideal for me?

Forty-five minutes is a good starting point. If you have ADHD or very high energy you can start with 30 minutes [citation:7]. Important: find your personal rhythm and stick to it consistently.

What do I do with emails and messages during focus time?

Nothing. Set fixed times for emails – and stick to them. During the 45-minute block there are no interruptions [citation:4][citation:7].

Can I apply the method while working from home?

Yes, it even works particularly well there because you set the conditions yourself. The Pomodoro technique is now often used in remote teams [citation:4].
