To choose your cardio training outfit, you should judge by your exercise level and frequency that require an appropriate level of technicality.
3 criteria can help you decide: Perspiration wicking, the lightness of the fabric and support.
1. Perspiration Wicking
When cardio training (treadmills, elliptical trainers or group classes such as step), the body perspires and the feeling of humidity is quickly felt if you don’t wear appropriate clothing. That's why the more intense the activities, the greater the need for breathable fabrics. They absorb moisture, transfer it to the outside and diffuse it to dry quickly. For intensive cardio training, opt for the most technical clothing with plenty of ventilation inserts in the back, at the back of the knees, around the waist...
2. Light Weight
To feel free in your movements, with no constraints, go for lightweight fabrics. You’ll forget about them during exercise for maximum comfort. For more intense exercise, the lightness of a fabric can be combined with a loose fit or close to the body for a guaranteed second-skin effect.
Cardio training also requires good support for the bust, to protect it from impact and to feel at ease when exercising. If you work out intensively, go for tank tops with a built-in bra, which are often more comfortable. In the most technical product ranges, support is optimal with fitted garments, elasticated waists and bras that can withstand the heaviest impacts, while avoiding the risk of chafing with ultra-flat seams.
Although it is important to feel good in the clothes you're wearing, it is even more important to wear clothing that is suited to your activity. Comfort and breathability are two characteristics to look out for while making a choice.
