“By measuring an athlete during all aspects of training, I made the important discovery that anaerobic stimulation, which can come from any anaerobic workout and any physical, chemical, or mental lifestyle stress, had the potential to interfere with the development of the aerobic system, thereby reducing endurance potential. An important aspect of building the aerobic base, I quickly learned, is that during this process, anaerobic training should be minimized—ideally eliminated—from the training schedule. And, athletes need to become more aware of how stress affects them.”
