Final answer:
Milo of Greece followed the principles of progressive overload and consistency while lifting a newborn bull onto his shoulders each day until the bull became fully mature.
Step-by-step explanation:
The principles of modern muscle strength and endurance conditioning that Milo of Greece followed while lifting a newborn bull onto his shoulders each day until the bull became fully mature were progressive overload and consistency.
Progressive overload refers to gradually increasing the weight or intensity of an exercise over time in order to continually challenge and stimulate muscle growth and adaptation. By lifting the bull every day, Milo was progressively increasing the load on his shoulders, forcing his muscles to adapt and become stronger.
Consistency refers to the regular and consistent performance of an exercise or activity. Milo's daily practice of lifting the bull demonstrates his commitment to consistency, which is crucial for building and maintaining muscle strength and endurance.
