Muscular endurance assessment, muscle overloading, and weightlifting routines are crucial in achieving muscle size and definition.
Muscular endurance can be best assessed through a repetition maximum test, which evaluates how many repetitions of an exercise a person can complete before fatigue sets in.
When training for muscle size and definition, like in John's case, overloading the muscles is crucial. This involves pushing the muscles to the point where additional repetitions are difficult to complete, promoting muscle growth and definition.
Weightlifting routines play a significant role in building muscle size and definition over time by gradually increasing the load and intensity of the exercises, leading to muscle adaptation and growth.
