F45 Training Changi Business Park runs functional group fitness classes that mix cardio, resistance and hybrid workouts, with a library the studio says is over 80 workouts. It is in Plaza 8 at 1 Changi Business Park Crescent, unit 01-24, in Changi, close to the office workers of the business park. Customers say the equipment is good and the setup makes sessions efficient. The trainers are the most praised part: members call them motivating, encouraging, patient and focused on form. Some regulars have trained for one to two years, and one says the sessions are demanding. One visitor found the entrance hard to find, since you go through glass doors facing the clinic and gym. Classes can be booked through ClassPass. BFT Changi, 0.1 km away, and Anytime Fitness Changi are the nearest rivals.
