The traditional class structure of doing a warmup, learning a couple of new techniques, and followed by sparring is NOT an efficient way to learn jiu-jitsu.  We can do much better if we use insights from research on coaching and learning. Today's guest is Cal MacDonald, a BJJ black belt and  competitor who has dedicated himself to developing his teaching and coaching skills to the highest possible level.   Cal is a longtime blackbelt under Rob Biernacki at Island Top Team. Rob and his team are at the cutting edge of teaching and training methodologies that make people amazingly good incredibly fast. Cal coached full time at Island Top Team for five years and is also a fierce competitor, having won Gold at NAGA, Pacific Northwest Open, and many other tournaments. He has travelled to top academies for Worlds and ADCC camps, training with top athletes like Yuri Simões, Mason Fowler, and Caio Terra, so he knows what works at the highest levels. His proudest accomplishments are the successes of his students, and he has spent thousands of hours coaching and cornering competitors as they fight their way to the podium. Cal stays abreast of advances in sports science and cognitive science, and blended that with experience and experimentation to create the BJJ Foundations program - more info about that at https://www.grapplearts.com/foundations Good luck with your training, Stephan Kesting
