Build Mental Toughness & Perform Under Pressure | Dr. Lenny Wiersma

Mental performance relies on structured psychological tools that transcend simple positive thinking. Dr. Lenny Wiersma, Director of Sports and Performance Psychology at UC Berkeley, emphasizes that visualization serves as a critical mechanism for both confidence-building and coping, provided it incorporates emotional depth and realistic scenario planning, such as preparing for equipment failure. Effective self-talk requires psychological distancing, where individuals use second-person language to coach themselves objectively during high-pressure moments. Furthermore, confidence is inherently fleeting and should be replaced by "robust belief"—a foundational state built through consistent self-care and diverse feedback sources. Emotional regulation, rather than control, allows performers to maintain focus by labeling emotions and determining the next actionable step. These strategies, when embedded within a team environment, enable coaches and athletes to maintain composure and performance consistency regardless of external conditions or unexpected adversity.
