Staying relaxed during your workout can help keep you focused on proper technique. Reach for shorts with an elastic waistband that offers a snug fit, or choose a pair with a drawstring to help ensure just the right feel as you sprint and jump. Mesh fabrics encourage increased air movement to draw away heat and sweat, and color-contrasting side panels add an eye-catching accent. Be sure to look for men's athletic shorts with pockets to keep your keys and other accessories close by as you head home after your training is over.
