F45 is a franchise chain of group training studios, so most of its branches run a similar format. Before you join, ask how the classes are structured, how many people share the floor, and whether a trial session is offered. Many regulars arrive a few minutes early to settle in and check the timetable. Check the contract terms for freezing or cancelling, since these vary more than the monthly fee suggests. Booking classes ahead is usually sensible, particularly at popular times.
The studio is in Wave Mall at Stadium Place in Kallang, so it suits people living or working nearby.
