In this very special episode of MASS Office Hours, Dr. Eric Trexler and Lauren Colenso-Semple are joined by a guest!
Dr. Brad Schoenfeld joins the show to deliver a masterclass on the science of muscle growth. Dr. Schoenfeld is a world-renowned muscle hypertrophy expert who has published countless research studies about muscle growth. In this episode, we discuss metabolic stress, rep ranges, “effective reps,” “hard sets,” training to failure, intensification techniques (supersets, dropsets, eccentric overload, etc.), exercise order, the importance of understanding scientific mechanisms, how to effectively apply research findings, and much more.
We made this episode extra special to kick off our huge Black Friday sale with a bang! Prices for all MASS subscriptions are the lowest they will ever be, and the sale extends from Nov 22 to Nov 29. Learn more at:
