The school gym's facilities were decent for this kind of thing, but not up to legendary training rooms that could, for example, create simulated combat situations.  No, instead there were super-tough versions of various training gear from hurdles to pommel horses to punching bags, plus superstrength weightlifting gear and some targets for testing accuracy.  There were also options to put large amounts of padding on the walls or other obstacles to stop high-speed impacts from being dangerous.

It certainly looked usable, Diana shifted over to her armoured form.

She shifted, and still had a little bit of time to decide on what exactly to have the students work on.

Probably some hand to hand combat basics. Everyone could use that.

Her students soon arrived.  Mary saw her in armor and clearly sighed, but the others were more interested... (Marume was nervous.  Kelly was grinning.  Which would be a bigger problem?)
