Jett's Fitness typically is very strict on their Joining Fee of $89, unless in certain cases such as when a new gym is opened.
There is however still a $59 Access Fee, which pretty much is for the swipe card access since the gyms are sometimes unstaffed and open 24/7.
Membership costs are either $489 a year in advance, or $11.95 weekly. More info is here
Personally, I've never joined, but went to a trial free 3 day period last week and it seemed like the streamlined basics (no pool, sauna etc.). I chuckled how all the cardio equipment had built in TV's e.g. treadmils.
Anyway, please comment on your experiences as a Jetts member as well.
There's probably a 5-7$/week gym near you these days, so unless you absolutely need a 24/7 gym, there's no reason to join Jetts. The Rockdale one I joined was small and lacking in equipment (no squat racks, just a Smith machine). Nice clean shower though :)
