I have been to both..

I went to Curves and signed up for a 12 month membership, they did not have any other option at that time (2 yrs ago)

They use hydrolic (sp?) like equiptment which means the harder you work, the better the results.

I found it got boring after a while because it was the same thing everytime (the "program" never changed) I started not going regularly and then stopping all together after only 3 months.

I am with contours now. and i LOVE it. I was paying $79 (month by month) in the beginning because i wanted to make sure that i would go..

They use weights and they change your program every 4 weeks to make sure you stay interested and keep getting results. You can do boxing, hoola hooping and everything!

Im paying $59 a month now.. on a 12 month contract.

I have lost 1.8kg and 10.5cms in 4 weeks!! and LOVING it!!

hope this helps a little
