24/7 FITNESS Jalan Besar is a gym in an upstairs unit at 9 Townshend Road in Kallang, on the Jalan Besar side of the neighbourhood, holding a perfect 5.0 rating on Google. As its name suggests, it opens day and night. For anyone weighing up a round-the-clock gym, timing is the first test: the quiet stretches usually fall mid-morning and mid-afternoon, so visit at the hour you would actually train and see how crowded it gets. Many 24-hour gyms run on keycard entry with little or no staff overnight, so look past the front desk to how well machines are maintained and floors are kept. Regulars judge these places on working equipment and free rack space at peak, not on extras — and for shift workers and night owls, the real draw is training whenever the day allows. A 5.0-rated gym on hand at any hour is a handy fixture for the Jalan Besar end of Kallang.
