Most men’s fitness and workout shorts are designed to be lightweight, wick moisture, resist odor and remain comfortable for the duration of activity. Some men’s running, gym and fitness shorts offer the extra security of an inner brief. Training sessions and competitive races are more enjoyable when your shorts are comfortable and you don’t have to worry about adjusting them. Men’s workout, running and gym shorts are often made with comfort drawstring waistbands and built-in stash pockets in the inner waist to keep your house key or other small items. New Balance, Saucony and K-Swiss are great brands to begin looking for your favorite new fitness shorts.
