Our lower body is arguably the ultimate weapon for a longer, healthier and fuller life. This simple, yet powerful foundation supports mobility, balance and independence, all key factors in aging well. Rather than trying to gather resilience via supplements and extreme workout routines, it is important to grow in the rhythms of daily life through natural movement, and continual usage of our lower body. To further boost our enthusiasm, the story of Ushi Okushima, a centenarian from Okinawa, Japan, epitomizes how this can be done with grace, joy and longevity
The power of our lower body
Functionality and strength in the legs and lower body are important components of healthy aging. Research has consistently demonstrated that stronger legs are associated with a lower risk of falls, disabilities, chronic diseases, and even cognitive decline. The muscles of the lower body-the quadriceps, hamstrings, calves, and glutes-serve as pillars supporting upright movement and balance. Falling is among the most common causes of injury and death in older adults, and strong-legs drastically reduce this risk through improved stability and functional independence.
Moreover, the strength of the lower body positively influences metabolic health through the facilitation of better insulin sensitivity and cardiovascular health necessary in the prevention of diabetes and cardiovascular diseases. Indeed, lower limb strength is an independent predictor of overall mortality-with stronger leg muscles associated with longer life expectancy and more years lived independently.
Ushi Okushima: Strength in natural living
Ushi Okushima was a renowned centenarian from Okinawa- Blue Zone of the world, known for its remarkable longevity-and an epitome of how natural movement on a daily basis builds resilience. Born in 1901 and having lived past 100 years, Ushi flourished with a simple yet deliberate lifestyle. She had spent most of her life either near or on the ground: sitting on mats, gardening, getting up, and kneeling down several times throughout her day. These very natural motions kept the lower body muscles in consistent action and contributed to strong, mobile later years. According to a podcast, “Fit with Kelly,” Ushi would sit and rise from her tatami mat around 30 times a day, repeatedly engaging and strengthening her lower body muscles naturally. These simple, mindful movements became a form of strength training woven seamlessly into ordinary life.
Ushi followed a purpose-driven routine, hinged on activities rather than exercise. Early mornings were for prayers and light meals of tofu miso soup and green tea, followed by long walks and hours tending her garden. She reinforced social connection through a "moai" group, or a mutually supportive circle that nourishes emotional and social well-being. As she grew older, Ushi adapted, changing gardening less and working part-time at a market. Her strength and flexibility avoided dependence on aids like canes-and she enjoyed healthy vision, hearing, and mental clarity.
Her story reminds us that strength is not about lifting heavy weights but about embracing movement as part of daily life. Sitting on the floor, using stairs, gardening, and walking with intention are all “exercises” that build the foundation of leg strength that supports longevity. Ushi ’s-ikigai, or reason for living, was deeply connected to family, friends, and community—another key ingredient in her remarkable resilience.
Building strength through lifestyle and easy exercises
While Ushi's life is an inspiration, the realities of modern life often eliminate natural movement, replacing it with convenience and sitting for long periods. Deliberate exercises to activate the lower body muscles are required. Bodyweight exercises such as squats, lunges, and calf raises are great for safely strengthening at any age. These movements activate major muscle groups responsible for quality enhancement in joint health, balance, and coordination-key defenses against falls and frailty.
Strength training can reduce the risk of falls in older adults by as much as 23%. This combination of an exercise regime, together with work on balance, maximizes stability. Safety first: proper form and gradual progression prevent injury and build confidence. More than muscle strength, strengthened legs are associated with improved cardiovascular health, metabolism, and even brain function through enhanced blood flow that prevents cognitive decline.
Natural movement as lifelong practice
Our bodies flourish with movement that is variable and functional. Gardening, walking, stretching, and sitting on the floor are all activities that stimulate muscles in ways machines or isolated exercises do not. Eating until 80% full, "hara hachi bu" as the Okinawans do, along with frequent natural movement maintains a healthy weight while minimizing metabolic stress. Getting up from low positions and climbing stairs regularly, along with intentional walking, creates an environment in which muscle strength and coordination thrive, much as in Okinawan elders like Ushi.
Rooted in daily life activities
True resilience and longevity don't come from complicated routines or expensive supplements; they come from daily habits that use our bodies naturally, from the lower limbs up, in support of every step we take. Ushi Okushima's life is a testament to how simple, consistent movements build health, strength, and joy into old age. Sitting on the floor, gardening, walking, and nurturing social bonds aren't solely cultural artifacts but rather practical, accessible ways to live longer and healthier lives. By embracing these principles of intentional movement, balanced nutrition, and meaningful relationships, we can all forge the ultimate weapon against the declines of aging.
It is time to honour our legs with care, strength and movement, they carry us through life and the least we could do is be taking care of them. Let the story of Ushi Okushima guide us through the path of health and longevity.
