CLOTHING FOR EXERCISE

As required for other exercises, dumbbell exercise clothing should be loose-fitting to permit freedom of movement, and should make the wearer feel comfortable and self-assured. As a general rule, you should wear lighter clothes than temperatures might indicate.
When the weather is very cold, it’s better to wear several layers of light clothing than one or two heavy layers. The extra layers help trap heat, and it’s easy to shed one of them if you become too warm. While in cold weather, and in hot, sunny weather, it’s a good idea to wear something on your head.
Never wear rubberized or plastic clothing, such garments interfere with the evaporation of perspiration and can cause body temperature to rise to dangerous levels.
