Weight Training
Luke's limbs ached with the memory of his previous training as he arrived at his next training spot, the Armored Terrain ground.
This ground was designed such that it improved the conditioning and stamina of a knight by exposing them to the various real life conditions that they might have to face while wearing their heavy armours.
For a Knight, their armor was 50% of their battle prowess, as good armor versus great armor often became the deciding factor between victory and defeat.
A knight's fighting style was extremely physical and crude, when compared to agility based styles such as swordsmanship and hence they needed the extra layer of protection as their fighting style did not necessarily need them to be fast or avoid attacks.
This particular training ground was made in a way that there was a large 2 mile track running across its edges that shifted from sand, gravel, mud, grass to obstacle course.
