The number of calories burned during a 1-hour Muay Thai kickboxing session can vary significantly depending on several factors, including the intensity of the workout, the individual's weight, age, gender, and overall fitness level.
However, on average, a person can burn anywhere from 600 to 1,000 calories in a 60-minute session. High-intensity sessions that include sparring, heavy bag work, and conditioning drills tend to be at the higher end of that range.
It's one of the reasons Muay Thai is considered an effective workout for improving cardiovascular health, strength, and endurance, in addition to being a powerful martial art.
