Hello! Poul Nielsen here with another health-related book review. This time we’re looking at Outlive by Peter Attia. As someone who has dedicated my life to fitness and helping others achieve their best selves, I found this book to be incredibly insightful and relevant to our mission here at Nielsen Fitness. So let’s dive in and see what we can learn from Attia’s work.


Outlive is a fascinating exploration of the science of longevity and how we can live longer and healthier lives. The author, Peter Attia, is a physician who specializes in longevity. He shares his knowledge and insights on how we can extend our lifespan and healthspan—that is, the period of life spent in good health. The book delves into the importance of preventive healthcare and how lifestyle choices can affect our longevity.

More about Lifespan vs Healthspan

Lifespan refers to the total number of years a person lives, while healthspan is the number of those years spent in good health. Unfortunately, in North America, there has been a misstep in healthcare that focuses on treating symptoms rather than actively preventing diseases through exercise and good lifestyle habits. It’s important to shift the focus to preventive measures to improve healthspan, not just lifespan.

5 Important Take-aways

This is a big book (500 pages!) with lots of information. Here are five high-level takeaways that stuck with me:

  1. The importance of preventive healthcare in extending lifespan and healthspan
  2. The role of exercise, diet, and sleep in promoting longevity
  3. The importance of managing stress and building resilience
  4. The need for personalized healthcare that takes into account individual differences
  5. The potential of emerging technologies and therapies to enhance longevity

my favourite tip from the book

One of the top tips from Outlive is the importance of strength training for longevity. As we age, we naturally lose muscle mass, which can lead to frailty and reduced independence. Attia emphasizes the importance of maintaining muscle strength through regular exercise to support a healthier, longer life.

And we couldn’t agree more. At Nielsen Fitness, we understand the importance of exercise for longevity. Our in-home, private personal training studio, and virtual personal training options are designed to keep you accountable and improve your strength, balance, flexibility, and mobility. Our trainers will work with you to create a personalized exercise plan that fits your lifestyle and helps you achieve your fitness goals.

I’ve seen firsthand the incredible transformations of clients of all ages right up to the 90s. Through consistency and effort, they have radically improved their fitness, vitality, and quality of life. The empowering effects of exercise are undeniable, and it’s never too late to start your journey towards a healthier, longer life.

Outlive is a must-read for anyone interested in longevity and improving their healthspan. Peter Attia’s insights and advice are invaluable and align perfectly with what we do here at Nielsen Fitness.
