In this Huberman Lab Essentials episode, my guest is Dr. Duncan French, PhD, the vice president of performance at the UFC Performance Institute and a world-class performance specialist.

We explain how resistance training and acute stress impact hormones and outline specific weight training protocols to increase testosterone to support strength and hypertrophy. We also discuss how to use cold and heat exposure to enhance recovery and performance. Finally, we explain how to match nutrition to training goals and improve metabolic flexibility.
