Most weight - training experts believe that muscular strength and muscular endurance are closely related. As one improves, there is a tendency for the other to improve also.
It is generally accepted that when weight training for strength, heavier weights with a lower number of repetitions should be used. Conversely, endurance training uses relatively lighter weights with a greater number of repetitions.
It has been suggested that endurance training should consist of three sets of 10 to 15 repetitions using the same criteria for weight selection, progression, and frequency as recommended for progressive resistive exercise? Thus suggested training regimens for muscular strength and endurance are similar in terms of sets and numbers of repetitions. Persons who possess great levels of strength tend to also exhibit greater muscular endurance when asked to perform repeated contractions against resistance.
