A good gym is judged less by its equipment list than by how busy it gets and how well the coaching is run. Visit a class before you commit to a membership, and look at whether the space is laid out so you are not standing in someone else's way. Ask how many people share a session, what the coaching covers for beginners, and whether a trial class is offered. Many regulars find that a short introduction saves time and avoids awkward mistakes on the first visit. Check the contract terms for freezing or cancelling, since these vary more than the monthly fee suggests.
The gym is in Kallang, an area with a good range of places to eat within easy reach, so it suits people living or working nearby.
