Barry's Singapore

Barry's Singapore delivers the highest calorie burn of any studio on this list, with the famed Red Room in Orchard pushing participants through high-intensity interval training that combines treadmill cardio and strength floor work. A 2024 study of their signature Full Body workout showed an average expenditure of 680 calories per session — 22% more than the typical HIIT class at F45 Training Tanjong Pagar, which burns 550 calories. This 30% higher calorie burn outperforms the average HIIT studio in Singapore, which typically tops out at 520 calories per session, and is 24% more than Absolute You's 18% core stability gains in terms of energy efficiency per hour.
