Welcome to the latest episode of L.I.F.T.S, your bite-sized dose of the Latest Industry Fitness Trends and Stories.
In this episode, hosts Matthew Januszek and Mohammed Iqbal are joined by Dr. Nick Barringer, a former U.S. Army performance leader, tactical nutrition expert, and human performance consultant, to explore how tactical training principles translate to success in business, leadership, and everyday life.
With over two decades of experience working with elite military units, high-performance athletes, and executive leaders, Nick breaks down what it really takes to perform under pressure: from decision-making while sleep-deprived, to building resilience, discipline, and sustainable habits that carry over far beyond the battlefield.
This conversation bridges the worlds of fitness, leadership, mindset, and strategy, offering practical insights that entrepreneurs, executives, and high performers can apply immediately.
In this episode, we cover:
• Why executives should think of themselves as “corporate athletes.”
• How sleep deprivation impacts decision-making and performance.
• Tactical principles that improve leadership under pressure.
• The role of fitness and conditioning in mental resilience.
• Nutrition and supplementation strategies for high-stress environments.
• What elite military training can teach us about business and life.
