When choosing clothes suitable for fitness, there are several key factors to consider: functionality, comfort, and safety. Functionality refers to the ability of clothing to absorb moisture, sweat, be breathable, and elastic, allowing the body to stretch freely during exercise. Comfort refers to the material and cutting of clothing that should make you feel comfortable during exercise, without creating friction or pressure. Safety includes not having parts of clothing that are prone to snagging equipment, and choosing clothing with reflective strips during nighttime exercise to improve visibility.

Specifically, clothes suitable for fitness include sports T-shirts, sports shorts, tight sports pants, sports vests, and sports jackets. Different types of exercise may require different clothing, such as lightweight sports shorts and T-shirts for running, while yoga is more suitable for wearing close fitting yoga clothes.
