Why progressive overload?
Progressive Overload refers to the practice of continually increasing the stress placed on the muscle as it becomes capable of producing greater force or has more endurance. At the beginning of a training program a certain weight may be a sufficient stimulus to produce an increase in strength or size. As the program progresses, the same weight will not be a sufficient stimulus to produce further gains in strength because the trainee can now easily perform a higher RM than before. If the training stimulus is not increased, no further gains in strength will occur. Different methods of progressively overloading the muscles are, increasing the resistance to perform a certain number of repetitions, increasing the total training volume by increasing the number of repetitions or sets, increasing repetition speed with sub-maximal resistances, changing rest period length between exercises and finally, changing total training volume by changing repetitions, sets and number of exercises performed
