depend...FF is monthly paid...while CF is selling package(such as min 18 months)...CF also got monthly paid like FF, but is not worth if u plan to go long term

like the package i join in january 2006, 2 years for RM1999 include all processing fees) + 5%government tax...means 1 month only RM87 ...

so if u only 'temporary' interested to gym only, join those monthly paid 1....can quit anytime...

however, like jetyap said, go to the 1 near to ur home or office...
like if u stay next to leisure mall cheras, for sure u should join FF instead of CF in mv or menara standard chartered...

also, FF has free soft drinks and borrow VCD...CF only got sky juice and no VCD to borrow...in terms of gym equipment almost the same
