LFMT Fight Club (Muay Thai) is a muay thai boxing gym in Geylang, Singapore. Google reviewers rate it 4.9 out of 5, from 166 reviews, a strong result for a gym of this kind.
A good muay thai gym is judged on the coaching and on how carefully beginners are taken through the basics. Newer students often find it helps to learn stance, footwork and basic kicks before sparring, and a good coach will say when you are ready. Ask whether classes are group or private, and what the class size is likely to be. Many regulars bring their own hand wraps and water, and check the changing and shower facilities before they arrive. A trial session is usually a sensible way to see whether the teaching suits you.
The gym is in Geylang, an older district with a mix of shophouses and eateries, so it suits people living or working nearby.
