Jennifer Hintenberger is a seven-time Kettlebell World Champion and nineteen-time World Record Holder whose journey from personal health struggles to elite athletic dominance has made her a sought-after voice on mental resilience and performance.
At 43, Jennifer consistently outperforms competitors half her age, both men and women. One of her world records includes lifting a 35lb kettlebell overhead 1,023 consecutive times in 60 minutes. She holds academic and practical backgrounds in Western and Eastern medicine, biology, and psychology.
Jennifer's keynote, Mind Over Everything, draws on her experience overcoming food addiction and serious health battles to reach extraordinary levels of athletic success. Rather than focusing on the physical side of her sport, she teaches audiences how to identify and rewire the beliefs that hold them back, using lessons drawn from both academic study and hard-earned personal experience.
Audiences leave with practical tools for reshaping their own belief systems, building consistency under pressure, and turning motivation into lasting change. Her message translates directly to teams navigating setbacks or sustained performance demands.
Book Jennifer to give your audience a science-backed, lived account of what it takes to redefine personal limits.
Topics, sessions and talks
Jennifer Hintenberger draws on her path from food addiction and serious health battles to seven world titles, showing audiences that physical achievement starts with rewiring belief. She breaks down the mental frameworks behind sustained high performance, drawing equally on her clinical training in medicine and psychology and her own competitive results. The talk moves past typical motivational language into specific, repeatable tools for shifting deeply held beliefs and building consistency under pressure.
Jennifer goes deeper into the science behind belief change, drawing on her background in medicine and psychology to explain how outdated thought patterns limit performance and how to replace them with frameworks that stick. Using examples from her own transformation and her work with athletes and executives, she gives audiences a step-by-step blueprint for identifying the beliefs that cap their potential and systematically rewiring them. The session is practical and evidence-based, designed for teams navigating performance plateaus or major change.
Jennifer regularly outperforms competitors decades younger than her — and she has the world titles to prove it. In this talk, she explores what it means to perform under sustained pressure across a long career, how to stay competitive as the stakes increase and the years accumulate, and why age-related assumptions about peak performance are simply wrong. The session challenges teams and leaders to stop treating pressure as a threat and start using it as the fuel behind their best work.
