Body Mechanics & Injury Prevention

Back injuries are the #1 workplace injury in the United States. Most are preventable. This skill is not for desk workers — it's for people who lift, carry, push, pull, climb, and stand for a living. Trades, construction, warehouse, food service, healthcare, cleaning, agriculture. The body mechanics that prevent injury are the same across all of these: use your hips, not your spine; keep loads close; and recognize warning signs before they become six weeks of disability. This skill covers proper technique, pre-shift warmups, and the early signals your body sends before something breaks.
