Membership Tips
Negotiate signup fees, they're often waived if you ask, especially mid-month or end-of-month. Annual prepay typically saves 10-20% over monthly. Corporate codes through your employer (or sometimes through condo buildings) cut prices further.
Read freeze and cancellation policies carefully, some chains require 30-day notice and only allow freezing twice annually. Don't commit to long contracts at gyms you haven't trial-used. Most premium chains offer 1-3 day passes ฿500-฿1,500 to test before joining.
