This depends on the school. Some more serious Muay Thai camps will require a high level of fitness before booking the course. Some are specifically designed to get you back into shape, while others require you to comfortably run 10km before signing up.  It’s important to choose the right Muay Thai school for your fitness level to avoid injury and overexertion. In most Muay Thai gyms, you’ll be doing at least two Muay Thai training sessions a day. You need to be mentally and physically prepared for the challenge! Muay Thai can be hardcore, but the reward, in the end, is worth it!
