Ark Move

If you live in Serangoon, Jurong or West Coast, then Ark Move just might be your sweet fitness spot. A membership with this gym gives you access to all three gyms, and you pay month-to-month – great for those who are just starting out (or simply have commitment issues). Membership rates are affordable too, topping out at $80 a month. Just note that there's a $100 initiation fee, though that can get as low as $40 during promotional periods.
