Muscles may move us, but bones build the blueprint. In this third installment of “The Prerequisites for Strength”, we go beneath the muscle to explore the skeletal system—the often overlooked, yet critical framework behind every lift, jump, and step. From density to durability, learn how to strengthen your bones, avoid the silent risk of fragility, and keep your architecture strong for the long haul. Because a powerful engine still needs a solid chassis. 🦴🧱💥

Before a single rep is lifted, real strength begins with something deeper. It’s not the sweat, the sets, or even the soreness that defines it — it’s the why behind the work.
