27 December 2023

Dr. Peter Attia shares his expert advice on choosing the right workouts for longevity

In the quest for a longer and healthier life, choosing the right type of workouts is crucial. Dr. Peter Attia, a renowned longevity expert, believes that incorporating four key pillars of fitness can help individuals stay fit and strong as they age. With a focus on strength, stability, steady cardio, and high-intensity exercise, Dr. Attia’s approach provides a comprehensive framework for maintaining optimal health and functional movement in older adulthood. In this article, we delve into each of these pillars and explore how they contribute to a longer, healthier life.

Strength – The Foundation for a Long, Healthy Life

Strength training, including weightlifting, forms the foundation of Dr. Attia’s longevity plan. By engaging in compound exercises such as deadlifts, squats, and shoulder presses, individuals can work multiple muscle groups simultaneously, mirroring the movements required in daily life. Research supports the benefits of strength training as we age, with studies showing that a combination of strength training and cardio can help prolong life. Dr. Attia emphasizes the importance of strength for practical applications, such as carrying groceries or lifting a suitcase, highlighting its relevance to everyday activities.

Stability – Preventing Injury and Maintaining Control

Stability plays a crucial role in physical vibrancy as we age. Being able to control our bodies and maintain balance becomes increasingly important. Dr. Attia recommends stability exercises such as step-ups and one-legged balances to enhance stability and prevent injury. These exercises not only improve balance but also contribute to overall health and well-being. Research suggests that the ability to balance on one leg can serve as an indicator of overall health. Incorporating stability exercises into a workout routine can help individuals maintain control and reduce the risk of falls or other injuries.

Steady Cardio – Boosting Heart Health

While strength training is essential for building and maintaining muscle, aerobic or cardio exercise is equally important for heart and lung health. Dr. Attia emphasizes the benefits of low-intensity cardio in promoting a healthy heart and enhancing overall stamina. Slow, steady aerobic exercise, such as walking or cycling, stimulates the growth of mitochondria, which provide energy to cells. This, in turn, improves energy utilization, stamina, and the body’s ability to handle physical strain. Incorporating regular bouts of low-intensity cardio can have significant long-term benefits for heart health and overall well-being.

High-Intensity Exercise – Small Doses for a Longer Life

In addition to strength and steady cardio, Dr. Attia recommends incorporating high-intensity exercise into a fitness routine. Intense workouts, such as climbing stairs or rucking (carrying a weighted backpack), offer numerous health benefits. One measure of cardiovascular fitness is VO2 max, which reflects the body’s peak ability to use oxygen during exercise. Maintaining a good VO2 max can reduce health risks and enable individuals to engage in various activities they enjoy as they age. Dr. Attia encourages individuals to challenge themselves with occasional bursts of high-intensity exercise to enhance their overall fitness and longevity.


Dr. Peter Attia’s four pillars of fitness – strength, stability, steady cardio, and high-intensity exercise – provide a comprehensive approach to staying fit and healthy as we age. By incorporating these pillars into our workout routines, we can improve muscle strength, prevent injuries, boost heart health, and increase overall longevity. Whether you are a beginner or an experienced athlete, it is never too late to start prioritizing your fitness. As Dr. Attia emphasizes, as long as you’re breathing, you have a chance to make a positive change and improve your health and well-being.
