AG2 research

I'm hoping at the weekend to get a big chunk of AquaGirl 2 written - as it's currently >5,000 words long and I've only covered half a day; and I'm intending this episode to last several days (more water-based training, starting her 'day job', evening computer fiddling, and her first mission), it might take a while longer to finish (although hopefully before a rather portly superhero piloting a rather improbable vehicle makes his seasonal appearance!)

Anyway, at the point I've written up to, Rena's about to do land-based testing in a gym at the navy base. If anyone's seen one (or used one), I'd appreciate answers to a couple of quickie questions:

a) I assume it'll have your standard set of gym equipment - weight machines, dumbbells, free weights, treadmills etc. - but roughly how big is the building / room? Classroom sized, sports hall sized - no need for exact measurements, just some kind of 'similar size to' reference point.

b) Are there likely to be any weighing scales in the vicinity, or shall I use the excuse of a variety of scales being stored in a cupboard for the use of the local WeightWatchers branch, who have meetings there every Tuesday evening? :)
