In Episode 250 of Muscles and Management, Gerry is joined by Dr. Antonella Schwarz, Assistant Professor of Exercise Science at Barry University, to break down some of the most intriguing findings in sports science research today. From bridging the gap between academic knowledge and practical coaching to challenging long-held beliefs about caffeine and performance, Antonella delivers evidence-based insights every coach and athlete should hear.

The conversation covers her work on skeletal muscle hypertrophy, the relationship between grip strength and maximal force output, and how muscle mass—not just body weight—drives long-term strength and health. They also dive into the real (and often misunderstood) effects of caffeine on performance, how research studies can be better understood and applied, and why simple tests often provide the most valuable coaching data.

This episode is packed with practical takeaways for strength coaches, sport scientists, and anyone serious about athlete development and long-term health.
