＞However, the recent literature shows a much wider range of training options. Several studies have found that training with low-loads (30−60% 1RM) results in similar hypertrophy to training with moderate and high-loads (>60% 1RM) when volitional fatigue occurs [11,14,15,16]. Moreover, reaching volitional fatigue at all times is not necessary to make significant gains in hypertrophy
