Fitness is equally important for women. When choosing fitness exercise, you sweat a lot. At the same time, when you exercise, there will be more friction between your body and your underwear. If you wear underwear with chemical fiber fabric, you must choose carefully. It is best to choose cotton underwear. The activities of various parts of the body increase during fitness, so underwear must have good elasticity, especially good supporting performance, to avoid excessive breast trembling when the body fluctuates up and down. Also, tights are generally worn during exercise, and the design of underwear should highlight the natural curve of the human body, and the obvious outline of underwear can not be seen from the outside of tights. At the same time, the shoulder strap of underwear should not slide down, so as not to bring you unnecessary trouble. It is suggested that wearing a split sports bra can make the chest curve fuller and rounder, because it has better support and built-in cup design. Wear it, your flat belly and graceful waist and buttocks will be more curved, and a pair of suitable shorts will make your beautiful and slender legs more charming.
