Review: Weights for Speed (One and Two)

So even if you are lifting at equal intensity, say 3 reps at your 4 rep max, the incline press is less CNS demanding because the overall weight is lower.

And if the reverse is true and you’re looking for the greatest CNS stimilus, would you then prefer half-squats over ATG squats or cleans?
