5 Key Concepts
Myokines
These are protein molecules secreted by muscles into the bloodstream when you move. Upon reaching the brain, myokines regulate various physiological and metabolic responses, affecting cognition, mood, and emotional behavior, acting as a 'love letter' between muscles and the brain.
Brain-Muscle Crosstalk
This refers to the communication stimulated by exercise between the brain and muscles. It includes the formation of new neurons and synaptic plasticity, which are fundamental to learning and memory, suggesting that building muscle literally builds brain health.
Sarcopenia
This is the natural, age-related loss of muscle mass that typically begins in one's 30s. It's important to combat sarcopenia through strength training to maintain overall body resources, support recovery from illness or injury, and improve metabolic function as one ages.
Muscle Memory (Cellular)
Beyond motor neurons remembering movement patterns, muscle cells themselves possess a form of memory, including cellular and epigenetic memory. This means that past exercise can turn certain genes on and off, making muscles more likely to bounce back and regain strength even after periods of inactivity.
Kissing the Ground in Equilibrium
This is an ancient term for the pushup, found in a book about physical health. It encapsulates the idea of performing a difficult physical act (going down to meet the ground) while seeking a state of balance and appreciation, serving as a mantra for navigating life's challenges.
9 Questions Answered
The three types of muscle are cardiac (heart muscle), smooth (lining organs and vessels), and skeletal (used for voluntary movement).
Muscles grow bigger not by multiplying cells, but by recruiting special muscle stem cells that contribute their nuclei to muscle growth and regeneration, repairing micro-tears that occur during activities like weightlifting.
Movement releases protein molecules called myokines into the bloodstream, which travel to the brain and regulate cognition, mood, and emotional behavior, stimulating new neuron formation and synaptic plasticity, which are the basis of learning and memory.
Western culture's ideal of muscularity dates back to ancient Greek sculptures, often depicting bulges where muscles don't even exist, while other cultures, like ancient Chinese medicine, historically focused on internal energy (chi) rather than visible muscle for health.
Having visible abdominal muscles (a 'six-pack') primarily indicates that a person is naturally lean, rather than necessarily having an extremely strong core, a common misconception according to anatomists.
Achieving physical feats or improving strength can build resilience and reframe self-perception, providing a sense of agency and control, which can spill over into a more open and adaptable outlook on life, countering the tendency to ossify as adults.
Maintaining muscle mass combats age-related muscle loss (sarcopenia) and bone loss (osteoporosis), providing the body with crucial resources to recover from illness or injury, and supporting overall metabolic and physiological functioning as one ages.
It's important to consume enough protein, though not to obsess over specific amounts, and to also eat a balanced diet including vegetables, grains, and complete proteins like rice and beans, subscribing to an 'everything in moderation' approach.
Generally speaking, creatine is considered a safe supplement with many decades of research supporting its use, typically taken in doses of 3-5 grams, but it's always advisable to consult a doctor due to potential underlying medical conditions.

1. Prioritize Muscle Movement for Brain Health
Engage in regular muscle movement, as it’s crucial for long-term brain health, especially as you age, due to the constant electrochemical conversation between your brain and muscles.
2. Consistent Weightlifting for Longevity & Brain Health
Incorporate weightlifting throughout your life to benefit both your longevity and brain health, as muscles secrete signaling molecules (myokines) that regulate brain responses.
3. Strengthen Muscles to Boost Brain Function
Engage in activities that bulk up your muscles, as this literally bulks up your brain by stimulating new neuron formation and synaptic plasticity, which are the basis of learning and memory.
4. Increase Muscle Mass for Enhanced Recovery
Build and maintain muscle mass, as greater physical strength and muscle resources enhance your body’s ability to recover from illness, injury, or other health challenges.
5. Begin Strength Training Early for Bone & Muscle Health
Begin lifting weights and strength training earlier in life to combat age-related muscle loss (sarcopenia) and bone loss (osteoporosis/osteopenia), shoring up your physical health for the long term.
6. Start Exercising at Any Age
Recognize that muscle is an incredibly adaptable tissue, capable of change at any age, so you can start regular exercise later in life and still experience significant benefits.
7. Activate Your Body’s Internal Pharmacy with Exercise
Engage in exercise, even for just a few minutes, to stimulate your muscles, brain, and other tissues to release a beneficial wash of chemicals that positively changes your body and mind.
8. Seek Professional Guidance for Weightlifting Form
When lifting weights, ensure you use correct form by seeking guidance from a trainer, physical therapist, or class instructor to learn the basics and prevent injury.
9. Consult a Trainer to Start Exercise Routine
To initiate a new exercise routine, consult a trainer or join a class to gain basic knowledge and overcome the initial activation energy, making it easier to integrate into your life.
10. Exercise with a Group for Motivation
Join a group of friends or a class for exercise, as social commitment and shared activity can make it more fun, reduce activation energy, and provide motivation to show up.
11. Discover Joyful Movement
Seek out forms of exercise and movement that genuinely bring you joy, such as dancing or other play-based activities, to make physical activity a happy and sustainable part of your life.
12. Embrace New Physical Challenges for Growth
Be open to new physical experiences and challenges, viewing them as opportunities for growth and potential change, rather than being limited by self-doubt or fear of discomfort.

5 Key Quotes
Muscles deserve more consideration than we give them. We often think about muscle as existing separately from intellect, and maybe even oppositional to it. One taking resources from the other. The truth is that our brain and muscles are in constant conversation with each other, sending electrochemical signals back and forth. Our long term brain health depends on muscles and moving them, especially when it comes to aging bodies.
Bonnie Tsui (reading from her book)
Bulking up your muscles literally bulks up your brain. And isn't that great? The whole thing of kids do better in school with PE, it's true. And I loved learning the hard science behind it.

Every pushup was a note to yourself that you were capable of more than you were the day before. These days, when so much of life feels out of our control, something concrete and tangible, however incremental, feels like a small victory. During the writing of this book, I've been doing a lot of pushups and thinking about what it means to do them. Lately, I've come to understand that what I learned from my father was not just to lift heavy things, but to lift myself.
Bonnie Tsui (reading from her book)
Your condition is exacerbated by not enough muscle. And I remember being in the room with her and hearing this doctor say this, Tara, and I went, what does that mean? And it's that if you don't have enough muscle, your body doesn't have enough resources to fix itself.
