In today’s demanding world—whether you’re lifting heavy, sprinting hard, or sitting at a desk for hours—your body constantly adapts to stress. But not all adaptations are positive. Poor posture, repetitive strain, and sedentary behavior can inhibit key muscle groups, leading to movement compensations, reduced performance, and a higher injury risk . That’s where Reflexive Performance Reset (RPR) comes in—a cutting-edge system of neuromuscular activation and breathwork techniq
