Sportswear worn by both athletes and non-athletes for physical activity is referred to as fitness merchandise. Therefore, the system is purposefully made to make strenuous physical activities like jogging and weightlifting in a gym convenient.

Since their fit is only suitable for general activities like sitting and leisurely strolling, regular clothing simply would not fulfill the function.

However, fitness gear is not limited to athletic wear. Also included are shoes designed specifically for sporting activities like running, jumping, and playing games. Sports footwear, helmets, body armor, T-shirts, and jeans are all included in the area of fitness items.
