Friend goes to fitness first (ahahahah)
and he tells me its 33.50 or so per fortnight, they will rape you if you sign a contract, even if its just for a casual visit (from experience)
and generally, you have to give them your bank details so they can just charge that directly, havent really heard of anyplaces that do memberships based purely on cash
never been to Golds, but from what ive seen, theyre alright
you should check them out beforehand and stuff though, not to sure what their repuation is in australia is
And, as with any gym, its only worthwhile if you go regularly, that is 3+ times a week
otherwise youre better off just going for a run every now and again or buying your own dumbbell set and bench
edit: YMCA ftw
