BITESIZE | The Surprising Truth About Exercise and Keeping Your Brain Healthy | Dr Tommy Wood #455

May 23, 2024 16m 40s 20 insights
It's easy to believe that we have to dedicate lots of time and energy to exercise. That, unless we're pushing ourselves to our limits, it's not worth doing. But my guest this week disagrees - as do I. Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests. Today’s clip is from episode 404 of the podcast with medical doctor and neuroscientist, Dr Tommy Wood. Like myself, Tommy is passionate about empowering you to take control of your health by simplifying the wealth of existing information and giving you practical, realistic recommendations. In this clip he shares his current perspective on movement and why you don’t need to exercise for hours to gain benefits for your body and your brain.

Actionable Insights

1. Low Effort, High Benefit Exercise

Understand that for most people, the amount of exercise needed to see significant health benefits is quite low; simply doing more than you currently do will be beneficial.

2. Avoid All-or-Nothing Exercise

Avoid the ‘all or nothing’ mindset regarding physical activity; any sustainable increase in movement, no matter how small, will provide health benefits.

3. Prioritize Daily Movement

Make daily movement a priority, as literally anything you can get up and do will be beneficial if you are currently sedentary.

4. Intensity-Time Exercise Principle

Understand that exercise benefits are a product of intensity multiplied by time; higher intensity allows for shorter duration, while lower intensity requires longer duration for similar benefits.

5. Reduce Sedentary Time

Actively reduce time spent sitting by incorporating strategies like using a standing desk or taking ‘movement snacks’ (e.g., a quick walk or stairs) once an hour.

6. Increase Daily Walking

Aim to increase daily walking, especially brisk walking, striving for 8,000 to 14,000 steps per day to significantly improve health and reduce mortality and disease risk.

7. Prioritize Resistance Training

Integrate resistance training into your routine to counteract age-related decreases in muscle mass and strength, which is vital for metabolic health, blood sugar control, stability, and preventing falls.

8. Expand Resistance Training View

Broaden your definition of resistance training to include any movement against resistance, such as carrying shopping bags, bodyweight squats, push-ups (even against a wall), yoga, and Pilates.

9. Progress Resistance Training

To ensure continuous benefits from resistance training, progressively challenge yourself by increasing difficulty over time, for example, moving from wall push-ups to floor push-ups.

10. Flexible Start to Movement

Do not feel obligated to follow a sequential progression through movement types; instead, start with any physical activity you enjoy and find sustainable.

11. Meet Activity Guidelines for Cognition

Target 150 minutes per week of moderate to vigorous physical activity, as per government guidelines, to achieve a statistically significant improvement in cognitive function.

12. Target METs for Brain Health

Aim for approximately 700 METs minutes per week of physical activity to achieve a significant improvement in cognitive function.

13. Vary Activity by Intensity

Select diverse activities like 30 minutes of brisk walking, 20 minutes of Pilates, 30 minutes of resistance training, 5 minutes of sprinting, or an hour of gardening, adjusting duration based on intensity for similar benefits.

14. Add HIIT for Advanced Benefits

Consider incorporating High-Intensity Interval Training (HIIT) as a beneficial addition once you are already performing resistance training and low-level intensity movement, to gain different physiological adaptations.

15. Weight Training for Cardio

Perform weight training to voluntary muscular failure (the point where you can’t do more with good form) to achieve cardiovascular benefits comparable to lower-intensity aerobic training.

16. Manage Exercise Stress

Be aware that exercise, particularly high-intensity forms, can be a stressor on the body; consider your overall life stress when determining workout intensity to avoid over-taxing your system.

17. Endurance Training (Optional)

Engage in very long periods of endurance training only if you genuinely enjoy it, as it is not considered essential for general health improvement for most people already meeting other movement goals.

18. Daily Gut Health Support

Consider incorporating AG1 daily to support digestion and enrich your gut microbiome with beneficial bacteria.

19. Use METs to Compare Activity

Utilize the Metabolic Equivalent (MET) system, which can be found via Google, to objectively compare the intensity and overall work of various physical activities.

20. Gym Benefits Beyond Lifting

Recognize that attending a gym provides additional benefits beyond just lifting weights, such as reduced sitting time and increased general movement from walking around.
