Entering the gym building doesn't actually immediately take you to the gym: instead you're in the temple. There's people meditating on one side, people training martial arts on the other. Maybe a small living quarters with a few beds. The actual way into the gym is at the back of the room: a large opening into the wall, almost like a cave entrance, decorated with flags and maybe a torch on either side. Next to it is Carlos as usual.
Go through, and suddenly you're back outside, in between cliffs. You're standing on tall perilous rock croppings, surrounded by sharp jagged rocks below (ideal would be seeing the raging sea below or something, but that's probably impossible to do). Important is that it should look super dangerous, the idea is that you're braving the harsh elements like the acolytes here do every day. The gym is a large room with lots of small rock paths and platforms, there's not really any large platforms. It should look like there's a bunch of tall spires almost that you're moving between.
