Heeeey, another Mosmanite!
Yeah, i was one of those people who used the trials at Mosman a lot
Sorry i ruined it for you guys
Pumphouse is ok, they are nicer people there than FF, and they let you do a walk around - probably (don't know for sure) let you get a trial too. Their major downfall is perhaps you wont like the equipment. They are a little... 'old'. If you like the chrome and shine of FF, they might get get a shock at the bright yellow, or Green, or whatever (can't remember exactly) they have on their equipment.
Also, remember they have moved, i made the mistake of turning up to the location up above the GPK pizza place, they have have packed up shop and moved near the Orpheum.
Actually!
Just remembered, their website may have a 'fill out a form, and get a free day' thing on it. Check it out.
There are not many gyms around the Mosman area, quite frustrating actually, I've been wanting to find a good (though doesn't cost $$$$$$) one for a while.
There is PCYC in north Sydney, super cheap, but their equipment reflects this. And not the easiest to get too, either.
