Your body is a marvel of evolutionary engineering, designed for movement, adaptation, and resilience. For millions of years, our ancestors squatted, climbed, crawled, and walked their way to incredible physical prowess. They didn't need scheduled "stretching sessions" because their lifestyle naturally maintained their flexibility. Their daily tasks were their mobility work. Fast forward to today. You sit at a desk, in a car, on a couch—often for more than 10 hours a day. Your body, still wired with the ancient expectations of movement, is slowly being reshaped by modern stillness. The result? Tight hips, a stiff back, rounded shoulders, and a general feeling of being trapped in your own skin. You might try to counteract this with traditional stretching, holding a hamstring stretch for 30 seconds, but the relief is often temporary.
