Every time you train you should be using a fresh pair of Muay Thai shorts. Nothing is worse than having someone using an old pair of shorts that have not been washed at the gym. Not only will your shorts smell like your body odor, it is also disrespectful to the people who are training around you.

Cleanliness is a very important aspect of training Muay Thai, which is why it is important for you to have enough pairs of shorts so you are constantly wearing clean shorts.

Most people will have between 4-8 pairs of Muay Thai shorts so they can rotate different pairs and wash them at the end of the week. However, that number will range depending on how often you want to wash your shorts and how much you train. In my opinion the more pairs of shorts the better.
