The standard contract is $39.00/month for a three year contract. Renewal dues after the three years are up are cheaper, like Channing's. Mine are $22/month. The $19 contract that's advertised is for alternate days of the week - you have to pick Tuesday, Thursday, and Saturday OR Wednesday, Friday, and Sunday. I believe it also has a $150 down payment and is limited to use of one club only.
There used to be something like 36 different offers available at one time
and within the past year the whole pricing structure has been overhauled to be much less complicated. Definitely ask for a two week pass to try it out first!
And be sure to take advantage of your orientation and first work out from your friendly Ballys personal trainer.
BTW, I should tell you that I walked in the doors of my Ballys at 257 pounds and ended up working there as a personal trainer. Who knows? It could happen to you too!
