Galaxy Boxing Gym Sengkang is listed as a gym in Serangoon, Singapore. It holds a 4.9 rating from 41 Google reviews.
A good boxing gym is judged first on its coaching and on how carefully beginners are brought in. Before any pad work or sparring, a sensible coach teaches stance, footwork, guard and how to move safely, and matches partners by size and experience. Watch a class before you join, and notice whether the instructors explain each drill and correct form. Many regulars find the first few months are about technique and fitness, not fighting, so it helps to set that expectation early. Ask about the contract terms, the gloves and wraps you need to buy, and how classes are booked.
Serangoon is a mature residential area with the MRT, hawker centres and shops close by, so a gym here suits people who train near home or after work. For anyone in the neighbourhood, Galaxy Boxing Gym in Serangoon is worth a visit to see whether its classes suit your level and goals.
