Why is the squat superior to the deadlift as posterior chain exercise?
I have a few questions regarding the argument given in the book that the squat is the superior exercise for developing the posterior chain.
As far as I can tell there are three reasons given:
1. The deadlift leaves out the adductors.
Can someone explain why this? I don't understand how hip adduction is involved in the squat. Am I right to assume that the adductors have some other function?
2. The squat has a longer range of motion.
The hip angle at the bottom of the deadlift doesn't seem that much greater that at the bottom of the squat. Would the extra weight moved in the deadlift not make up for the slight loss in the range of motion at the hips?
Also, couldn't you use a deficit deadlift to decrease the hip angle?
3. The squat involves the stretch reflex.
I accept that this will increase the force you are able to produce when performing the squat, but is there any evidence that will translate to a greater increase in strength outside of the context of the squat?
