Hard flexing, or intense muscle contraction, can lead to passing out due to a phenomenon called the Valsalva maneuver. When muscles are intensely contracted, especially during weightlifting or straining, it increases intrathoracic pressure, temporarily reducing venous return to the heart. This diminishes cardiac output and lowers blood pressure. The body's response to this drop in blood pressure is a reflex bradycardia, which further decreases blood flow to the brain, potentially leading to sync
