About the book

Ultraproductive

The 90-Minute Method for More Focus, Better Sleep, and Less Stress

Thriving in today's overstimulated world has never been harder. To keep up, we treat ourselves like machines—constantly multitasking, always "on," and never truly unplugging. But this relentless hustle is backfiring: we struggle to focus, wake up drained, and feel stressed even when we're not working.

What if the secret to achieving more and stressing less isn't about doing more, but about working with your body and mind instead of against them?

In Ultraproductive, authors Eric Partaker and Dr. Christian Poensgen reveal the transformative power of the 90-Minute Method—a simple, science-backed approach built around the 90-minute ultradian rhythm that governs both our days and nights.

Instead of another endless list of tips and tricks, their method focuses on the three fundamental levers of a successful and fulfilling life:

Focus: Master the art of deep focus to get twice as much done each day—without working more.

Sleep: Unlock the power of restorative sleep to wake up rested and energized—without sleeping longer.

Stress: Learn to break stress cycles and use stress as fuel for growth—without burning out.

Drawing on cutting-edge research and their combined expertise in neuroscience, psychology, and business, Partaker and Dr. Poensgen present a practical framework to help you not just survive but truly thrive at work and at home.

Packed with actionable strategies, relatable examples, and fresh insights, Ultraproductive is the essential guide to achieving more and stressing less in an increasingly hectic world.
