Outside Training Area and Obstacle Course
Although on the Ground Floor, it is easier to get to the Outside Training Area and Obstacle Course via cutting through the tower. Otherwise, it is quite the trek over some rather punishing ground to make your way around the tower to get around the back.
The Training Ground, at first, doesn't look very impressive. It simply looks like a flattened area surrounded by a jagged rock landscape. However, when one of the Titans enters the circular clearing, the viewing platform emerges from the floor and boots up the training protocols. Someone may be present on the platform to manipulate the Area and throw different obstacles in the current users way.
