A good gym is judged less by its equipment than by how it is kept and run. Look at whether the floor and changing areas are clean, whether the machines are maintained and spaced so you can move between them, and whether the equipment you need is free at the times you train. Many members find that a trial visit tells them more than any listing, so try the place at the hour you would really train. Ask how beginners are guided, and whether staff can adjust exercises for injuries or older members. Check the membership and cancellation terms before you sign anything.
North Bridge Road runs through Kampong Glam and the Bugis area, with the MRT and many cafes and shops close by, so the gym is easy to fit around a day out or a commute. For anyone in the neighbourhood, Ground Zero at Odeon Towers on North Bridge Road is worth a visit to see whether it fits your routine.
