ON MUSCLE

A celebration of musculature in varying degrees and aspects.

Tsui recalls growing up in the shadow of an “impressively fit father” who lived and breathed exercise, was a tae kwon do and karate brown and black belt, and insisted the author and her brother train with him in a makeshift home gym in the garage. As a result, she grew into adulthood with the same preoccupation with “outrunning death” as her father did. These vivid memories fuel a multifaceted book exploring how the human musculoskeletal system is composed, how it functions, the ways to keep it optimally functioning as we age, and why it’s so critically important to daily life. To elaborate on themes of muscular strength and resilience in relation to the female species, Tsui profiles Jan Todd, the first female weightlifter to lift the Scottish Dinnie Stones in 1979, and Jan Suffolk, who, after embarking on a training regimen, would go on to become one of the world’s strongest women. Sections involving the author’s discussions on anatomical dissection are thought provoking and serve as apt reminders of the voluntary and involuntary muscle control we take for granted in everyday life, such as shoulder movement, heartbeats, posture, jumping, and even smiling and arching one’s eyebrows. The author of Why We Swim, Tsui discusses paralytic diseases and traumatic accidents that profoundly affect quality of life and what neuroscientists have discovered about the benefits of twitchy muscle movements during sleep to update and improve the brain-body connection. Undeniably fascinating is Tsui’s assessment of the biggest human muscle (the butt) and the smallest (the ear’s stapedius or the little muscle “goosebump” fibers). She also elaborates on the endurance of marathon runners and the mind-body connection where the brain interacts with the body to move its complex framework and network of bones, tissue, nerves, and senses. Grafting physical science with smooth, amiable storytelling, Tsui’s study creates a fun and fact-filled physiology lesson for readers of any knowledge level.

An easily digestible, reliably entertaining appreciation of muscle, “the vivid engine of our lives.”
