Hello; Whether you want the sleeves of fitness clothes, please say what kind of fitness programs you want to participate in first, such as sprint, gymnastics, rhythmic gymnastics, etc. It is best not to have sleeves, because these events will affect the accuracy of the action. Tai Ji Chuan had better have sleeves (some had better be short-sleeved shirts) for fitness dancing and table tennis in the Old People's Square. In fact, there is a good way to choose clothes. If you want to take part in a TV competition, you can see what the athletes wear. That's the best choice for clothes. Look at this.
