Peak contractions in shortened positions do matter even if percentage wise they lead to slightly less adaptation. But that does not mean they are neglected altogether especially if the majority of your quad training is at eccentric or lengthened positions. Also, pausing in a deep stretch is only valuable if that position is loaded. But in a seated leg extension, that’s not the case. In fact, it has zero load in the bottom stretched position, making any rest at the bottom totally ineffective for any muscle hypertrophy. . . . . . #legextension #strength #hypertrophy #muscle #musclesize #muscletoning #fitness #workout #gym #gymmotivation
