Basic Skeletal Muscle Physiology - The Motor Unit

generally speaking:
12+ rep range= musclular endurance
8-12= hypertrophy (cross section)
1-5=strength ( Recruitment)

Methods of compensatory accleration= discharge rate

Please note this has much variance among individuals.

With regards to your question of whats best? well depends on the goal…but surel Max strength (low reps) is the ebst way to go for recruitment.
