The Surprising Truth About Exercise with Professor Daniel Lieberman #128

Oct 20, 2020 1h 45m 31 insights
Today’s episode will change the way you feel about exercise – and yourself. Do you ever feel guilty for taking the lift instead of the stairs? For swapping that workout for a lie in, or for having zero desire to run a marathon? If so, my guest has some reassuring words on why an aversion to exercise is completely natural. And some valuable advice on how we can overcome that to reap the multiple health benefits.  Dr Daniel Lieberman is a paleoanthropologist and Professor of Human Evolutionary Biology at Harvard University. He has studied evolution and researched cultures all over the globe, to explain the science of how and why we move today. Whether you struggle to exercise or you’re a committed fitness fan, I think you’ll find his new perspectives on physical activity absolutely fascinating.  Among the many topics we cover in this conversation, Daniel addresses the following questions: Can exercise really help you lose weight? Does running ruin your knees? Should we be running barefoot? Is sitting the new smoking? Do you need eight hours’ sleep a night?  Should activity levels decline with age? I think some of his answers might really surprise you. I hope this conversation helps you feel better about the role of exercise in your life and have more compassion for yourself. I think it might just inspire you to move more, too.

Actionable Insights

1. Work With Your Biology

Understand your body’s evolutionary history and work with its natural inclinations to find sustainable health solutions, rather than fighting against them.

2. Normalize Aversion to Exertion

Recognize that the instinct to avoid exertion is completely normal and natural, and do not feel guilty or ashamed about it.

3. Integrate Fun & Necessity in Exercise

Approach physical activity like education, making it both necessary (through commitment) and enjoyable to overcome natural resistance and sustain engagement.

4. Avoid Guilt & Shame

Refrain from blaming yourself or others for struggles with physical activity or weight loss, as these often stem from deep-seated biological instincts.

5. Personalize Your Movement

Adopt an individualized approach to physical activity, focusing on finding ways to move your body more that genuinely work and are enjoyable for you.

6. Leverage Commitment Contracts

Implement formal or informal commitment contracts (e.g., financial stakes, social agreements) to create accountability and make physical activity a necessary obligation.

7. Find an Exercise Buddy

Partner with a friend for exercise to create social pressure and accountability, which can help overcome reluctance and ensure consistent participation.

8. Prioritize Leisure Activity

If your job involves prolonged sitting, consciously engage in physical activity during your leisure time, as this is more predictive of overall health than work-time sitting.

9. Practice Interrupted Sitting

Break up long periods of sitting by getting up and moving every 10-15 minutes, as this ‘interrupted sitting’ offers significant metabolic benefits and reduces inflammation.

10. Vary Sitting Postures

Incorporate diverse sitting postures, such as sitting on the ground with legs out, squatting, or kneeling, to engage different muscles and avoid prolonged static positions.

11. Increase Activity with Age

Challenge the cultural norm of becoming less active with age; instead, increase physical activity as you get older to maintain muscle health, slow aging, and activate repair mechanisms.

12. Combine Cardio & Strength

Build your fitness program on a bedrock of cardiovascular exercise, but also incorporate strength training for a balanced approach that aligns with evolutionary needs.

13. Moderate Activity for Immune Health

Engage in moderate levels of physical activity to upregulate key components of your immune system, boosting immune cell production and enhancing vaccine responses.

14. Start with Simple Joyful Movement

Begin your movement journey with simple, enjoyable activities like dancing in your kitchen for 10 minutes, rather than feeling pressured to do more complex exercises.

15. Remove Exercise Barriers

Proactively eliminate obstacles to exercise, such as laying out workout clothes the night before, to make it easier to start your activity even when motivation is low.

16. Question Health Cultural Norms

Critically evaluate societal norms related to health (e.g., specific sleep hours, sitting posture) and determine if they genuinely work for your biology in the modern world.

17. Re-evaluate Sleep Needs

Question the cultural norm of needing exactly eight hours of sleep; recognize that individual sleep requirements vary, with epidemiological data often pointing to seven hours as optimal for many.

18. Address Running Pain Causes

If you experience pain from running, investigate the underlying cause (e.g., existing damage, improper form) rather than just treating the symptoms, and consider adjusting your running style.

19. Running is a Learnable Skill

Understand that running is a skill that can be improved; focus on learning proper form and technique to reduce injury risk and enhance performance.

20. Adopt Forefoot Running Strike

Consider transitioning to a forefoot strike (landing on the ball of your foot) when running, as it can reduce impact and head jiggling compared to a heel strike.

21. Gradual Barefoot Running Transition

If interested in barefoot or minimalist running, transition very gradually and slowly, learning the proper skill of running to gain benefits and avoid injury.

22. Experiment with Barefoot Movement

Try walking or running barefoot for short distances on smooth, safe surfaces to reconnect with your body’s natural mechanics, starting slowly to prevent injury.

23. Walk Barefoot in Your Garden

Begin your barefoot journey by walking in your garden or backyard to gradually re-familiarize your feet with direct ground contact.

24. Dance for Health & Fun

Incorporate dancing into your routine as a culturally universal and enjoyable form of physical activity that offers both social and health benefits.

25. Walk During Meetings

Integrate physical activity into your workday by getting up and walking during meetings, or by having ‘meetings on the hoof’.

26. Reduce Chair Back Reliance

Be aware that constant reliance on chair backs reduces muscle engagement in your back, potentially leading to weakness and lower back pain.

27. Functional Strength Over Extreme Muscle

Aim for functional strength necessary for daily life and healthy aging, rather than pursuing extreme muscle mass, which is a modern and energetically expensive goal.

28. Support Diverse Exercise Methods

Avoid judgment regarding how others choose to be physically active; support any method that works for an individual to achieve their movement goals.

29. Leverage Social Pressure for Habits

Use positive social pressure or accountability (e.g., the desire not to be seen as a hypocrite) to motivate yourself to maintain positive habits like taking the stairs.

30. Creative & Inclusive Activity Promotion

As a society, develop more creative and inclusive approaches to physical activity that accommodate diverse fitness levels and disabilities.

31. Run for Knee Health

Understand that running is generally healthy for your knees, promoting cartilage growth and maintaining joint health as you age, contrary to common myths.
