Just moved recently, and moving boxes upstairs made me realise how out of shape I am. Thought I'd do some googling to see what gym I can throw money at to eventually not go to.

Click your state. There's details for weekly plans etc, but seems to be yearly $249 (plus $59 admin), or $12.95 weekly (plus $59 admin).
Personally, I may see what personal trainers in the area, then maybe go down and see what the place is like before I lock myself in…
Man I pay way too much for a gym membership. This is great value. Unfortunately my local derrimuts is always full of bikies.
