Can heavy deadlifts improve pull ups?

Heavy deadlifts can indeed enhance your performance in pull-up exercises. According to Sal Di Stefano and Adam Schafer from the Mind Pump Podcast, performing heavy deadlifts activates and recruits a significant amount of muscle fibers across the entire back, which contributes directly to increased pull-up performance. They describe a noticeable improvement in doing pull-ups after heavy deadlifting, attributed to the extensive muscle activation from the deadlifts. This suggests a complementary relationship where heavy deadlifts can prepare and enhance the muscles used during pull-ups 1.
