In the original Yautja films, they ran incredibly fast. They also possessed lightning reflexes, as well as a small amount of armour. In AVP, their armour was signifigantly added to, causing them to be fine with the extreme cold of Antarctica, but also making them considerably slower. Think about it. Pred 1/2 preds had maybe 20 pounds of it. In AVP, their full suits were at least 100 pounds (not the actor's suit, I mean the armor).
